Mining of simple sequence repeats in chloroplast genome of a parasitic liverwort: Aneura mirabilis
(2013)
Aneura mirabilis is a parasitic liverwort with a chloroplast genome size of 108007 bp. In this study simple sequence repeats (SSRs) were detected using bioinformatics approch in plastid genome of Aneura mirabilis. Due to its small genome size only 19 repeats were detected showing a density of 1 SSR/5.68 kb. The length of SSRs ranged from 12 to 20 bp. Mononucleotide repeats were the most frequent repeat type (36.84%) followed by tetranucleotide repeats (31.58%). Moreover hexanucleotide repeats were absent in chloroplast genome sequence of Aneura mirabilis.

The identity of Braunia alopecura (Brid.) Limpr. with Braunia secunda (Hook.) Bruch & Schimp.
(2013)
Braunia alopecura, originally regarded as species endemic to the Southern Alps, later known in addition from the the Cape Verde Islands and recently reported from the Indohimalaya, has revealed to be identical with the neotropical Braunia secunda. This is another case of an American species in the Southern Alps and in Europe in general, as well as an example of possible long distance dispersal.

The location of Ticino in the southern Alps with an altitudinal range from 200 to more than 3000 m generates a high biodiversity of bryophytes, however, in addition, a mixture of mediterranean elements (caused by mild temperatures), atlantic elements (caused by high precipitation) and especially insubrian elements (confined to the Southern Alps) has attracted many famous bryologists over the past 150 years and make this region to a real bryological hot spot. Six of the 7 insubrian species are mainly distributed in North America. Their presence in the Southern Alps is correlated with a certain geological formation and their origin is not clear.

Anomalies in female receptacle of Plagiochasma appendiculatum Lehm. & Lindenb.- A report from J&K.
(2013)
The genus Plagiochasma belonging to the order Marchantiales has been very well worked out with respect to the structure and development of male and female receptacles. In the present paper, the author reports abnormalities in archegoniophores along with the anatomical details of the same. This report from J&K is altogether new.

Comparative evaluation of antimicrobial activity of methanolic extract and phenolic compounds of a liverwort, Reboulia hemispherica was carried out by Agar well diffusion technique. The Gram positive bacteria were more sensitive than the Gram negative ones, while the fungal species were least sensitive. R. hemispherica extract exhibited best results against Staphylococcus aureus, although it was active against all tested microbes. The antimicrobial activity increased with the increase in the concentration of the extract except in Klebsiella sp. S. aureus, E. faecalis and Bacillus cereus were inhibited more by the crude methanol extract of R. hemispherica than the phenolic compounds isolated from the extract. A. niger was inhibited equally by the crude methanol extract as well as the phenolic compounds. B. subtilis, E. coli, P. aeruginosa, K. sp. and P. notatum were inhibited more by phenolic compounds than the crude methanol extract of R. hemispherica. Thus phenolic compounds of R. hemispherica should be studied further for use as antimicrobial agent.

Microsatellites also known as simple sequence repeats (SSRs) are short repeat motifs (1-6 bp) found in DNA sequences Detection of microsatellites is important for the development of molecular markers and to study the mapping of traits of economic, medical or ecological interest. In the present study, chloroplast genome sequence of Anthoceros formosae, downloaded from the National Center for Biotechnology Information (NCBI) was mined with the help of MISA tool to detect SSRs in chloroplast genome (cpSSRs). A total of 67 SSRs were detected with a density of 1 SSR/2.4 kb in 161.162 kb sequence mined. Depending on the repeat units, the length of SSRs ranged from 12 to 18 bp for mono-, 14 to 46 bp for di-, 12 to 27 bp for tri-, 12 to 20 bp for tetra and 18 bp for hexa-nucleotide repeats. Mononucleotide repeats were the most frequent repeat type (35.82%) followed by dinucleotide repeats (25.37%). Penta-nucleotide repeats were not detected in chloroplast genome sequence of Anthoceros formosae.

Scanning electron microscope analyses of sporoderm of 7 species of 3 genera of Marchantiales are presented in this study. In the studied species, sporoderm exhibit a broad range of morphology and have taxonomic specificity. The structurally rigid sporoderms have specific sculpturing and characteristic patterning. Peculiar architectures are found in different taxa, which revealed that and stable architectures may be present within an order. Sporoderms usually have specific surface markings which are often one of the best parameters to identify any species.

Thalloid liverworts with unistratose thallus margins are easily determined as Aneura maxima, which shall be identified by this character. However, forms of Pellia epiphylla and P. endiviifolia grown under humid conditions can have an unistratose undulate thallus margin and thus confused with the latter. Pellia species can, however, be distinguished from Aneura by the presence of slime hairs vz. slime papillae, which are described and illustrated here.

Hot spots are characterized by the occurrence of „hot“ species, rare, endangered, phytogeographically (for example highly disjunct) or ecologically interesting species (for example heavy metal species). The Apuanian Alps (ital. Alpi Apuani) are a place of extraordinary botanical and also bryological interest. Although situated far from the west coast of Europe, many atlantic species are found there, which have isolated occurrences and show up next in Asturias, Macaronesia. Ireland or Scotland. Representative of the oceanic element in the bryoflora are Dumortiera hirsuta, Lejeunea lamacerina, Lophocolea fragrans, Plagiochila exigua, P. bifaria, Saccogyna viticulosa, Harpalejeunea ovata and Marchesinia mackaii, supplemented by ferns such as Trichomanes speciosum and Hymenophyllum tunbrigense (Cortini-Pedrotti et al. 1992). Reasons for the presence of such species in Italy are the extraordinary climatic conditions. Situated directly along the Meditrerranean Sea, the climate is mild and due to depressions in the gulf of Genova, the rain is caught by the mountains resulting in a high precipitation of about 1400 at the foot of the region and more than 3000 mm in the summit region. This does, however, not explain whether these species are relics from the Tertiary or dispersed from the W-coast of Europe after the Pleistocene glaciations.

In the present study the level of S, Cu, Cr, Cd, Zn, Pb and Cr was estimated in samples of the common thalloid liverwort Plagiochasma rupestre (G. Frost) Stephani, from Ranthambhore National park, Rajasthan (India). High metallic load was observed both in substrate as well as in plant tissue at locations adjacent to higher vehicular load, during winter the metallic content is highest, followed by summer and monsoon season. Elemental concentration in substrate for Plagiochasma rupestre was in the order of Zn> S> Pb> Cu> Cd> Cr, while in plant tissue it showed S> Zn> Pb> Cu> Cd> Cr, which is indicative of air borne trace elemental load. Quantitative analysis of these elements in vegetative thalli of Plagiochasma rupestre and the substrate showed an increase in metallic content during winter, which reveals the significance of this liverwort as a biological sink of mineral elements present in the soil and air and may provide an important tool in estimation of both aerial pollution and mineral enrichment in soil.

A boat dug out of a Alnus (alder) trunk about 4,000 years ago had the space between the transom (stern) board and the slot cut in the hull caulked with mosses principally a mass of Anomodon viticulosus but there were thirteen other mosses and one liverwort. The mosses allow the tentative deduction that the boat may not have been caulked at Degersee or, if caulked there, the mosses had been gathered elsewhere in the vicinity and brought to the boat.

Dicranodontium didymodon, a species described from the Himalaya was recently reported from Spain. It has been distinguished from D. denudatum by a smooth subula. A reexamination of the type of this species revealed no additional characters which would support the recognition of a separate species. Therefore D. didymodon is synonymised with D. denudatum. The specimen from Spain is referred to D. denudatum var. glabrum, which differs from D. didymodon by larger stature and lack of brood leaves.

In the past, many bryophyte species were regarded as endemic to the Alps. Herzog listed more than 70 examples. Many of them are micro-endemisms or merely alpine forms of other species (Leptodontium styriacum) and not of taxanomic value, or considered as relics from the last interglacial period, although the Alps were covered by glaciers during the last ice age, which made a survival almost impossible, especially for forest species and epiphytes. Several of these species turned out to occur as well in Asia (Distichophyllum carinatum) or were described from there under a different name (Tayloria rudolphiana as T. delavayi). So far, one important species, Brotherella lorentziana, remained unsolved. A recent study revealed that this species is present in Asia, where it is known as B. henonii. At the present state of knowledge, five species namely Herbertus sendtneri, Riccia breidleri, Barbula bicolor, Marsupella ramosa and Trochobryum carniolicum must still be considered as endemic.

Die Energiedispersive Röntgenspektroskopie (EDX) ist so empfindlich, dass sie physiologische Chloridwerte bei Moosen und Gefäßpflanzen leicht erfassen kann. Bei dem halophilen Moos Desmatodon heimii werden hohe Cl-Werte in stoffwechselaktiven Teilen (unreife Sporogone) wie auch in abgestorbenen und abgestoßenen Blättern nachgewiesen. Als Vergleich zu salztoleranten Gefäßpflanzen diente die Salzsode (Suaeda maritima (L.) DUMORT.).

During the analysis of collections made by the author and company in Madikeri (Coorg) district the need of an updated checklist became eminent. Literature studies were carried out alongside with the identification of specimen. Liverworts were added to the existing checklist of mosses of Karnataka. Location information of previous publications has been critically revised and reflected in the current list. An extended history of the bryological exploration of the state of Karnataka is given.

Die Beobachtung einer verbreiteten Sippe aus dem Bryum capillare Komplex mit nicht schraubig zusammengedrehten Blättern, nicht austretender Rippe und schmalem Blattsaum warf die Frage auf, ob es sich dabei um einen Genotyp handelt und wenn ja, welchen Namen er tragen muss. Zunächst wurde geklärt, dass die Nominatform von Bryum capillare Pflanzen mit stark schraubig zusammengedrehten Blättern, austretender Rippe und starkem Blattsaum umfasst, die genannte Sippe also nicht dazu gehört. Ein Versuch belegte, dass die Nominatform in hyperhygrischer Kultur unverändert blieb, die abweichende Sippe also keine Hygromorphose oder durch Übergänge mit der Nominatform verbunden ist. Sie war von Schimper als Bryum capillare var. α bezeichnet worden und wird hier als var. schimperi legitimisiert. Gleichzeitig wird die im Flachland und Mittelgebirge auf basischen Felsen und Mauer beheimatete Sippe aus dem Bryum capillare Komplex, welche fälschlicherweise als Bryum elegans bezeichnet wurde, als Bryum capillare var. simile neu beschrieben.

During the past years, Fontinalis specimens with round, concave leaves were collected in Germany and Spain, which were named as F. antipyretica var. mollis. A comparison with the type of F. mollis revealed that they are not identical and accordingly are described as new variety, F. antiypretica var. rotundifolia.

The family Geocalycaceae are one of the largest families of leafy liverworts in India consisting of 9 genera and 27 species belongs to two subfamilies. Present study reports the distribution of members of this family in Kerala state. In Kerala the family Geocalycaceae are represented by 11 species belonging to three genera viz., Heteroscyphus (6 species), Chiloscyphus (3 species) and Lophocolea (2 species). Among these Chiloscyphus muricatus and Heteroscyphus bescherellei are new record of occurrence for the state of Kerala.

Neue Nachweise von Baltischem Bernstein durch den zweiten Autor zeigten mehrere Moose und Lebermoose, die beschrieben werden, und hier dargestellt sind. Unter den Lebermoosen war eine zweite Aufzeichnung von Ptilidium pulcherrimum sowie der Jungermannia berendtii, Aufzeichnungen von Cylindrocolea dimorpha in drei verschiedenen Proben und Frullania Baltica. Die Moose beinhalten eine unbekannte Art, die neu beschrieben wird als Ditrichites ignotus.

Reproduction in bryophytes is by asexual as well as sexual means. Asexual reproduction is a significant adaptation to special environments and occurs by a large variety of methods. During the last few decades, many of the bryophytes, particularly the dioecious ones are reported to have registered a decline in their fertile populations. There is, therefore, a need to understand the reasons for their disappearance.

Der Südrand des Kyffhäuser im nördlichen Thüringen ist eine der trockensten (500 mm Jahresniederschlag) und wärmsten (10° Jahresmitteltemperatur) Regionen Deutschlands. Zudem wird er von Zechstein-Gipsen gebildet, die sehr wasserdurchlässig sind und nur eine geringe Bodenauflage haben, sodass große Partien von Natur aus waldfrei sind. Daraus resultiert eine für Deutschland ziemlich einzigartige Vegetation, die nur in Anklängen auch im Südharz und im Unstruttal zu finden ist. Sie besteht aus kontinentalen Steppenelementen (Stipa, Adonis, Mannia fragrans), mediterranen Elementen (Riccia ciliifera, Tortula brevissima, Tortula revolvens, letztere von Reimers als Wüsten-Steppenmoose bezeichnet) und arktisch-alpinen Elementen (Athalamya hyalina, Tortella densa).

Growth of nine species of cyanobacteria was observed on eight species of bryophytes (thalloid liverworts and mosses) growing in the polyhouse, Bryophyte conservatory (Moss House), at National Botanical Research Institute, Lucknow, India. Bryophytes were cultured in the laboratory and transferred to polyhouse for hardening and acclimatization. Cyanobacterial growth was observed on the bryophytes as a contamination due to which there was suppression of bryophyte growth. It was evident that cyanobacteria played a significant role of allelopathy.

Combined data from chloroplast and mitochondrial genome sequences showed paraphyly of bryophytes
(2013)
The present study was conducted using chloroplast and mitochondrial genome sequences of plants to gain insight on evolutionary relationship of bryophytes. The representative taxa were selected considering the availability of both organelle genome sequences. Phylogenetic analysis using combined data from chloroplast and mitochondrial sequences infer paraphyly of bryophytes.

Les Vosges appartiennent, du point de vue bryologique, aux régions de l’Europe moyenne les plus riches et les plus intéressantes en espèces. Malheureusement, il manquait pour les présenter une flore synthétique. En 1989, l’auteur avait publié à son compte une première édition en 100 exemplaires d’une Bryoflore des Vosges dans laquelle, pour la première fois, toute la littérature bryologique avait été exploitée et enrichie par ses données personnelles. Celle-ci avait été complétée par un carroyage qui donnait ainsi un aperçu de la connaissance bryologique de cette région. Treize ans plus tard, une deuxième édition de ce travail fut publiée dans la revue « Limprichtia ». Les deux éditions furent traduites en français parce qu’il était important qu’une flore régionale portant sur une partie du territoire de la France soit publiée dans la langue de ce pays. Le texte de la première édition avait été traduit par une collaboratrice de l’auteur et fut revue par René Schumacker. Les compléments apportés au texte de la deuxième édition ont été traduits par Michael Häussler , René Schumacker en ayant à nouveau revu la traduction. Francis Bick a revu le texte et a traduit les nouvelles adjonctions apportées à la Bryoflore des Vosges à l’occasion de cette troisième édition.

The present study is a compilation of moss flora of Western Himalayas (India). This compilation listed 745 species of mosses, belonging to 19 orders; 55 families and 230 genera. Out of these 17 species have been reported endemic from Western Himalayas. 196 species have been synonymized and status of 86 species is still doubtful i.e. unresolved name. At present out of 745 only 463 species are validly known from this mountain range of India

Im Rahmen einer jetzt schon ganzen Reihe von Gebietsmonographien soll hier die Moosflora ausgewählter „hot spots“ im Lahntal zusammengestellt werden. Grund ist, dass – wie schon früher erwähnt – eine einfache Möglichkeit eröffnet werden soll, sich ohne große Recherchen über die Besonderheiten der deutschen Moosflora zu informieren, zumal aber auch der Personenkreis, der solche Zusammenstellungen erbingen kann, insbesondere aus eigener Anschauung, immer kleiner wird und bei der deutlichen Abnahme von floristisch ausgebildeten Bryologen oder lokalfloritsisch orientierten Mooskennern eine Zusammenstellung von Nöten wird.

Barail Wildlife Sanctuary (BWS) lies amidst the tropical forests of the state Assam, India between the coordinates 24o58' – 25o5' North latitudes and 92o46' – 92o52' East longitudes. It covers an area of about 326.24 sq. km. with the altitude ranging from 100 – 1850 m. An ongoing study on the group Marchantiophyta (liverworts, bryophyta) of BWS reveals the presence of 42 species belonging to 24 genera and 14 families. Among these, one genus (Conocephalum Hill) and 13 species are recorded as new for the state of Assam, eight species have been found which are endemic to India, seven species are recorded as rare and one species, Heteroscyphus pandei S.C. Srivast. & Abha Srivast. as threatened within the study area. Out of 24 genera identified, 46% have been found growing purely as terrestrials, 25% as purely epiphytes and 29% have been found to grow both as terrestrials as well as epiphytes. Among these, a diverse and interesting range of microhabitats have also been observed for each taxon. It has been found that genera having vast range of microhabitats comprise large percentage of the total liverwort flora of BWS.

The present phylogenetic analysis was conducted using mitochondrial genome sequences of plants to infer evolutionary relationship of bryophytes. Paraphyly of bryophytes was shown by reconstructed trees. Liverworts are the first to diverge therefore appeared as sister to land plants in nucleotide based trees. However protein sequences based tree show mosses and liverworts to form a joint clade. Hornworts formed sister relationship with vascular plants.

Fontinalis antipyretica var. mollis is recorded for Spain, which differs by orbicular, not keeled leaves. The presence in the same tufts together with var. antiypretica reveals that it is a somatic mutant of the latter. A form of Pellia epiphylla was observed which has wide thallus margins of unistratose cells resembling those of Aneura maxima. A Campylopus was collected resembling C. flexuosus but with ventral stereids in transverse section of the costa. It is described as C. flexuosus var. anomalus. An (unsuccessful) attempt has been made to find the locality in which P. Allorge found Campylopus setifolius for the only time in the Iberian Peninsula. The bryophilous fungus Octosporella jungermanniarum is reported as new to Spain. Dicranodontium didymodon, known before from the Himalaya and western China, is reported as new to Europe.

The availability of organelle genome sequences in public databases facilitates the reconstruction of land plants phylogeny. Therefore the present phylogenetic analysis was conducted using chloroplast genome sequences of plants to study phylogenetic relationship of bryophytes. The representative taxa were selected considering the availability of organelle genome sequences in database. Inferred tree topologies showed paraphyly of bryophytes with sister relationship between hornworts and vascular plants irrespective of the method (Maximum Likelihood and Bayesian Inference) and type of sequences (Nucleotide and Protein) used. Among bryophytes liverworts are the first to diverge therefore appeared as sister to land plants. Moreover land plants formed a monophyletic group.

Allelopathic effect of Stichococcus bacillaris Nageli (Green Alga) on the growth of two bryophytes
(2013)
Stichococcus bacillaris (Green Alga) growth was observed as a contaminant on two taxa of bryophytes, a thalloid liverwort Lunularia cruciata (L.) Dumort. ex. Lindb. and a hornwort Folioceros physocladus Bharad. ex Schiffn. et Pande, growing on soil in pots in acclimatization chamber of Moss House at National Botanical Research Institute, Lucknow, India. Due to this algal contamination, suppression of growth of these bryophytes has been observed. It was evident that succession of Stichococcus bacillaris and its interaction with bryophytes played a significant role of allelopathy.

In Europa wurden 30 Arten identifiziert, welche in Nordamerika in einem geschlossenen Bereich vorkommen, in Europa jedoch nur lokal vertreten sind. Wahrscheinlich wurden sie während dem Holozän verteilt. Diese Annahme wird durch die weitreichende Verstreuung in der nördlichen Hemisphäre unterstützt.

Similipal Biosphere Reserve is a part of biotic province of Chhotanagpur Plateau. It has a representative ecosystem under Mahanadian biogeographic region. Its biodiversity is an assemblage representation of Western Ghats and North-East India. Regarding bryophytes this area was rather unexplored and the current investigation shows the occurrence of 33 taxa of bryophytes in this biosphere reserve and its neighboring areas. Each species has been enumerated with its ecological and distributional details.

En 1989, la première compilation de la bryoflore des Vosges et des zone limitrophes paru avec la collaboration de D. Lamy, G. Philippi, V. Rastetter, R. Schumacker et J. Werner (FRAHM 1989). Pour la première fois elle contenait une présentation de la bryoflore d'une partie de la France avec des cartes de distribution en réseau. Cette première vue d´ensemble fut complétée par RASTETTER (1990), WERNER (1990) et FRAHM (1991), traveaux incluant d´autres espèces nouvelles pour les Vosges. 5 ans plus tard FRAHM (1994) ajoutait de nombreuses informations sur la bryoflore et surtout indiquait 16 espèces nouvelles pour la région.

Fährt man mit dem Zug durch das Rheintal zwischen Bonn und Bingen, so ist man von dem schroffen Kerbtal mit seinen Efeu-bewachsenen Schieferfelsen, nackten Felskuppen, niedrigen Eichenwäldern, Weinbergen und nicht zuletzt Burgen fasziniert. Bei genauerem Hinsehen vor Ort erweisen sich diese Habitate jedoch ganz überwiegend bryologisch als langweilig. Es herrscht sauerer Schiefer vor, auf dem Hypnum, Ceratodon und Polytrichum piliferum doninieren; die Wälder sind trocken, Die Felsen von Brombeeren und Schlehen überwachsen und undurchdringlich, nackte Felsen mit Bryum argenteum bestanden. Interessante Orte gibt es nur wenige, die im Folgenden zusammen- und vorgestellt sind.

The present study deals with the investigation of bryophytic flora of Mukteshwar (Uttarakhand). The present account deals with the study of 38 species belonging to 31 genera of 21 families. The mosses are represented by 21 species of 20 genera and 12 families, while Liverworts are represented by 15 species of 10 genera and 8 families. Hornworts consist of 1 genus and 2 species. The dominant families are Aytoniaceae, Marchantiaceae, Thuidiaceae and Pottiaceae. The dominant genera are Plagiochasma, Targionia, Marchantia, Plagiochila, Atrichum, Thuidium and Pogonatum. Macrothamnium stigmatophyllum has been identified as new to western Himalaya, while Thuidium philiberti Limpr. is new to Uttarakhand.

Das Untere Moseltal erstreckt sich von Trier bis zur Mündung in den Rhein bei Koblenz. Es liegt zwischen dem bryologisch gesehen relativ artenarmen quarzitischen Hunsrück im Süden (vgl. Archive for Bryology 69) und der Eifel im Norden und führt überwiegend durch Devonschiefer. Bryologisch interessant wird es durch eine Vielzahl von Xerothermelementen, deren Vorkommen durch die steilen, oft südexponierten Felspartien begünstigt werden. Diese gelten wie die mediterranen Faunenelemente an der Mosel (Würfelnatter, Sattelschrecke, Gottesanbeterin, Smaragdeidechse etc.) als Relikte des postglazialen Wärmeoptimums mit 2-3°C höheren Mitteltemperaturen, die sich an kleinklimatisch begünstigten Stellen haben halten können. Diese Hypothese ist jedoch unbelegt, da Moose sich auch später über Sporen angesiedelt haben können. Genauso brauchen Vorkommen mediterraner Vögel wie die der Zippammer keine Relikte zu sein. Die Frage ließe sich heute nur über die genetsichen Distanzen der DNA Sequenzen moselanischer und mittelmeerischer Populationen klären. Die Frage schließt ein, ob die Vorkommen auf Einzelansiedlungen von Arten zurückgehen, oder ob sich Relikte der mediterraner Moosvegetation in Form von Resten von Moosgesellschaften handelt, da im Boreal ganze Moosgesellschaften und nicht Einzelarten eingewandert sind. Von Hübschmann (1967) arbeitete übereinstimmende Vegetationsaufnahmen aus Südfrankreich in seine Tabellen von der Mosel ein und kam dadurch zum Schluss, dass es sich um identische Gesellschaften handelt.
