Bryophytes are a familiar group of non-vascular, nonflowering and seedless plants. Mosses, hornworts and liverworts are together referred to as bryophytes.
This study was conducted to assess the efficacy of SCoT and DAMD molecular markers in genetic diversity of three moss species and compare them with ISSR marker. Another objective was to evaluate the suitability of these DNA markers in species identification (delimitation) in three moss species, including Neckera complanata, Homalothecium sericeum and Neckera crispa. To prevent ecological impact on results, all samples were collected from one locality. PIC and MI in three markers showed closely ranged values. Our results revealed that the average values of Rp and the number of species-specific bands in SCoT primers were more than those of DAMD and ISSR. It showed considerable capability of SCoT marker in discriminating individuals. The highest value of genetic parameters Na (1.08), He (0.15) and I (0.23) were obtained with SCoT marker showing the power of this marker in genetic diversity analysis. Moreover, dendrograms produced from SCoT and DAMD data indicated similar results in the placement of closely

Sphagnum is a type of moss. Mosses are small, soft, non-vascular land plants placed in the Division Bryophyta. Mosses are typically one to ten centimeters tall (0.4 to four inches), although some species are much larger. They commonly grow close together in clumps or mats in damp or shady locations. They do not have flowers or seeds, and their simple leaves cover the thin wiry stems. At certain times, mosses produce spore capsules, which may appear as beak-like capsules borne aloft on thin stalks. Mosses can be distinguished from the apparently similar liverworts (Marchantiophyta or Hepaticae) by their multi-cellular rhizoids. Other differences are not universal for all mosses and all liverworts, but the presence of clearly differentiated stem and leaves, the lack of deeply lobed or segmented leaves, and the absence of leaves arranged in three ranks, all point to the plant being a moss. In addition to lacking a vascular system, mosses have a gametophyte-dominant life cycle. In other words, ...
Bryophyte herbarium samples were collected during two main types of field work: floristic explorations and vegetation studies. Field samples are separated into storage specimens during the species identification in a way that in each specimen was a minimum number of bryophyte species. Two label copies are generated for each sample. One copy of the label was fixed on a bag with a dried moss sample, the second was stored in a separate storage for labels (library card catalog cabinet is used). The labels and the moss specimens themselves were arranged in alphabetical order of species names. Each moss sample was assigned a catalog number. The catalog numbers were incrementing since the organization of the bryophyte subdivision in the SYKO herbarium. Information about the label catalog number, date of collection, name of the collection place, species name, field number, and habitat were entered in the register books. The labels from label storage were used for digitization. The label images were ...
Characteristics of Divisions Division Bryophyta - (9,500 sp.) - mosses, Mnium, Sphagnum Mosses come in two basic types, a cushiony type, with erect stalks, and a feathery type, which forms flattened mats of low-lying and highly branched moss plants. In both cases, the leafy green gametophytes are dioecious They can be male plants, with antheridia at the top of the plant, or female plants, with archegonia at the top. Remember that these gametophytes are always haploid (1N) plants. Sperm are produced within each antheridium, and an egg in each archegonium. Because the plant is already haploid, these gametes can be created by mitosis, simple cell division. The sperm swims to the archegonia through a thin film of water, drawn by a chemical attractant produced by the female plant, then swims down the neck of the archegonia to the egg. A good morning dew is more than sufficient water for the sperm to swim. Once the sperm enters the archegonia, it fuses with the egg. The 2N zygote develops into a ...
INTRODUCTION. Most bryophyte species are considered poikilohydric organisms because they present a rudimentary control of water loss and depend on environmental humidity (Kappen & Valladares 2007). Mosses usually are able to tolerate desiccation and return to full metabolic activity briefly after rehydration (Proctor et al. 2007a, 2007b, Waite & Sack 2010). Desiccation tolerance (DT) is the ability to dry equilibrating plant tissues with air that is moderately to extremely dry and then regain normal function after rehydration (sensu Alpert 2005). Many moss species are able to lose 90-95 % of their water, resulting in a physiological state with no liquid phase in their cells, but they can return to normal metabolism and growth short after rehydration (Tuba et al. 1998, Alpert 2000). Despite the many studies regarding DT in mosses, few studies address the possible underlying mechanisms (Proctor et al. 2007b). After 90 % water loss or more, desiccation-tolerant plants seem to be absolutely dry and ...

Harold Ernest Robinson (born 1932, Syracuse, New York) is an eminent botanist and an entomologist. Dr. Robinsons systematic knowledge encompasses many groups of plants and even some insects. But his real specialty is the sunflower family (Asteraceae) and the bryophytes. He has named or described over 2,800 new species and subtribes, that is more than one tenth of the number of species in the Asteraceae. This figure is also about one quarter of the number of flowering plants, described by Linnaeus. He has written over 650 publications, mainly on the Asteraceae, mosses (Bryophyta), Marchantiophyta, and the long-legged fly family Dolichopodidae (describing over 200 new species and 6 new genera, such as Harmstonia and Nanomyina) and many other subjects. He received a B.S. from Ohio University in 1955, an M.S. from the University of Tennessee in 1957, a Ph.D. from Duke University in 1960. After a short stint (from 1960 to 1962) as assistant professor at Wofford College (Spartanburg, South Carolina), ...
Like other members of the nonvascular plant phylum Bryophyta, mosses require water (even in the form of heavy dew) to assist in reproduction.
Mosses are traditionally used as ornamental plants, especially in Japan, USA, England (moss gardens) and Germany, French (green roofs). In shadow areas (where the members of Poaceae usually cannot grow well), mosses are potentially use as grass. The stocks of moss colonies maintain optimal microclimate and decrease desiccation of soils (l...ike mulch). Additionally, mosses are evergreen, attractive all year, during winter. In our study, 18 moss species were propagated by fragments (as mixture, with the use of 16 species) and transplantation of carpets (with Brachythecium rivulare and Calliergonella cuspidata) in Szentendre. The aim was to find the most durable species and the best way of propagation. In an outdoor, irrigated garden, propagation by fragments was effective (with 63% coveration) and higher values (93% and 76%) were obtained in the cases of non-irrigated stocks of Amblystegium serpens (in trays) and moss carpets. In vertical structures (moss picture-frames with the use of ...

A system of broad classification which recognized a plant kingdom of four divisions and an animal kingdom of ten to fifteen phyla was for many years stable and standardized. Significant changes have occurred, or are now proposed. Among these, three major lines of development are discussed: a. Classification of the algae has been fundamentally revised; seven or more algal series are distinguished primarily by characteristics of cells. The phylum concept, long established in zoological classification, has been brought into botanical classification in the systems of Pascher (1931) and Tippo (1942), in which the major algal series, the Bryophyta, and the Tracheophyta are regarded as phyla. b. Many authors have advocated recognition of kingdom of lower organisms, to meet the difficulty of dividing these between the plant and animal kingdoms. Two major possibilities for such a third kingdom are the Protista of Haeckel (1866, 1894), essentially identified with the unicellular organisms, and the Proctoctista of

For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes, with the first being physiological ecology, but including an introduction to the broad classification of phyla and classes, morphology, structures, and life cycles. Communities, habitats, roles, and uses, among others, are in various stages of completion. [Information of the supplier, modified ...
CLEAVITT, NATALIE L. Department of Biological Sciences, University of Alberta, Edmonton, AB T6G 2E9. - Disentangling moss species limitations: the role of substrate specificity. Substrate specificity has been pinpointed as key both in explaining plant species distributions and in differentiating types of plant rarity. The relative importance of substrate specificity to moss occurrence and rarity was evaluated for the rare moss species, Mielichhoferia macrocarpa, Mnium arizonicum and Didymodon johansenii and the taxonomically allied common species, Bryum pseudotriquetrum, Mnium spinulosum and Didymodon rigidulus var. icmadophilus, respectively. Substrate pH and percent organic matter were measured within five sites for each species. Sensitivity to these two substrate parameters was tested by a fragment regeneration experiment on native and non-native substrates. Evidence from field plot data and establishment experiments further resolved the role of substrate specificity in limiting M. ...
The hypothesis that moss peat respiration in the maritime Antarctic was dependent more on edaphic conditions, substrate quality and microflora than latitude was broadly supported by studies on a 14° transect in 1980-81. Oxygen-uptake and CO2-release of samples from Polytrichum and Drepanocladus communities at five locations were compared by ANOVA. Regression analysis showed moisture and temperature to be prime regulators. A strong but unquantifiable influence of substrate quality was inferred. The influence of microbial biomass was blurred by variation. the absence in Polytrichum of significant multiple regressions of respiration with moisture and temperature implied stable respiration during a summer period of relatively invariable moisture, pH, Eh and potential substrate availability. Conversely, the occurrence of Drepanocladus in a broader range of moisture conditions yielded a significant regression. When extrapolated to estimate annual C-loss, this was similar to estimates for the 1975-77 ...
Bryophytes are important components of many kinds of vegetation, especially in moist or cold biomes, such as arctic tundra, alpine heaths, boreal forest, various types of wetlands, mountain cloud forest and tropical rainforest. In total, about 22 000 species are described, and more than 1200 of these are known from Scandinavia. The bryophyte lineages - mosses, liverworts and hornworts - originated and diverged during the early colonization of terrestrial habitats by plants. They have retained key roles in ecosystems, such as water retention, nutrient cycling and primary production (photosynthesis). These roles have historically often been misunderstood or neglected, but modern research have resurrected the importance of bryophytes and pointed to their position as evolutionary links between the first land plants and more recent groups of plants, such as the flowering plants.. You will study representatives of these lineages to learn about their morphological characters, reproductive strategies, ...

Spoon-leaved Moss (Bryoandersonia illecebra), of the family Brachythecieaceae, is a shiny, green to greenish yellow-brown species of moss with creeping stems and ascending, intertwined branches that form deep mats. It is quite large and striking compared to most moss species, making it relatively easy to find and identify in the field. Its most distinctive feature is the smoothly cylindrical rat-tail appearance of its stems and branches (especially when they are dry). Upon very close examination of the stems and branches, one may discern closely overlapping, broad, concave (cupped, like the bowl of a spoon, with the dish opening toward the stem) leaves, up to 2.8 mm in length, covering all surfaces. The leaves narrow abruptly to short, twisted points. These characteristics help to distinguish the species from other large, branchy species of moss that overlap Spoon-leaved Moss in distribution.
Bryophytes are land plants and have tissues and enclosed reproductive systems, but lack vascular tissue for circulating liquid. They do not have flowers and reproduce via spores rather than producing seed. Bryophytes are mosses, liverworts and hornworts.. ...
Plants have been growing on land for at least 450 million years. The bryophytes comprising the three phyla liverworts, mosses and hornworts, are considered to be the closest extant relatives to the plants that colonized land. Bryophytes has been described as evolutionary unchanging sphinxes of the past regarding both morphological and genetic potential. This suggestion has some support in limited studies of molecular evolution within bryophytes, but has also been questioned based on e.g., studies of species diversification rates. To shed more light on this controversy, the overall aim of this thesis is to investigate rates and patterns of bryophyte molecular evolution.. Our data suggest that the per nucleotide mutation rates in bryophytes are lower than those in angiosperms. Likewise, angiosperms are also more dynamic in terms of genome size, structural rearrangements, genome duplications and transposon activity. However, our data show that mutation rates of bryophytes are higher or at least ...

Hylocomium splendens, photo by Koch. Hylocomium splendens may produce more total biomass than any other moss in the world. It is found throughout arctic and cool temperate regions of Eurasia and North America, and it even shows discontinuities in some similar parts of the Southern Hemisphere. Despite all this abundance, and despite its great abundance even in nearby areas of Oregon and Washington, Hylocomium splendens has been found in only three sites in extreme northern parts of California. It is an immediately recognizable moss that produces repeatedly pinnately branched with strong heterophylly between the lanceolate leaves of the main upwardly arching stem and the concave and ovate to almost orbicular tiny leaves of all other orders of branching. It is commonly called the stair-step moss because of the pattern of new pinnate fronds of each year arising from central portions of the main stem of the previous years growth. Key to Hylocomium Etc. The plants included in this section are ...
Bryoerythrophyllum columbianum, the Columbian carpet moss, is one of four species of Bryoerythrophyllum in North America. It is a small, often red-brown moss that grows in small clumps or compact turfs either as pure colonies or intermixed with other mosses and lichens. Its most distinctive features are the ovate-lanceolate leaves, sharp-pointed leaf tips, and the broad, somewhat ornamented leaf mid-ribs. It is dioicous, with male and female organs on separate stems.
Over last couple of weeks I have been writing up the new additions to Breconshire since Ray published his Bryophyte Flora (ill put it on Brecks vc page of BBS web site in a week or so). Anyway, I started on a Syntrichia papillosa note, then realised that the record was actually located in Glam and not Brecks (and corrected some time later in BBS Field Bryology report). It is known not too far away from Brecks boundary in Abergavenny area and just into Radnorshire in Wye Valley. Thinking it must be somewhere in Usk valley and having taken the day off to finish some flooring, I thought I would have a quick walk around Llangynidr to see if I could find the Syntrichia (after all the Field Guide tells us that it is something of an urban species), before getting on with the DIY - the third elder I looked there was one small patch of the moss! Other than that though it was difficult to spot much in gloom and rain, so other bryos were mainly bread and butter stuff, with just single patches of Cryphaea ...

AU - Wellman, Charles H.. AU - Yang, Ziheng. AU - Schneider, Harald. AU - Donoghue, Philip C.J.. PY - 2018/3/6. Y1 - 2018/3/6. N2 - Establishing the timescale of early land plant evolution is essential for testing hypotheses on the coevolution of land plants and Earths System. The sparseness of early land plant megafossils and stratigraphic controls on their distribution make the fossil record an unreliable guide, leaving only the molecular clock. However, the application of molecular clock methodology is challenged by the current impasse in attempts to resolve the evolutionary relationships among the living bryophytes and tracheophytes. Here, we establish a timescale for early land plant evolution that integrates over topological uncertainty by exploring the impact of competing hypotheses on ...

AU - Sanders, Dale. PY - 1997/3/1. Y1 - 1997/3/1. N2 - In caulonemal filaments of the moss Physcomitrella patens red light (fluence rate 85 μmol m-2 s-1) triggers within 2-15 s a transient membrane depolarization, and 3 d later the development of side branch initial cells. Both the rapid electrical events at the plasma membrane and the morphological response are Ca2+dependent, phytochrome-mediated and effectively inhibited by the cation channel blocker TEA (10 μM) and the anion channel blocker niflumic acid (1 μM). This suggests that both responses are connected. Current voltage analyses of the red light-induced current combined with ion flux measurements revealed that Ca2+, K+ and anion-permeable channels are open at the peak of the alepolarization. While Ca2+ influx and anion efflux coincide with ...
A class of plants within the Bryophyta comprising the mosses, which are found in both damp (including freshwater) and drier situations. Mosses possess erect or prostrate leafless stems, which give rise to leafless stalks bearing capsules. Spores formed in the capsules are released and grow to produce new plants. (Concise Dictionary of Biology, 1990). Many small plants bearing the name moss are in fact not mosses. The moss found on the north side of trees is actually a green alga (CHLOROPHYTA). Irish moss is really a red alga (RHODOPHYTA). Beard lichen (beard moss), Iceland moss, oak moss, and reindeer moss are actually LICHENS. Spanish moss is a common name for both LICHENS and an air plant (TILLANDSIA usneoides) of the pineapple family. Club moss is an evergreen herb of the family LYCOPODIACEAE. . ...
Pteridophytes are plants with Feather like Leaves. Pteridophytes are a group of primitive land plants belongs to the Cryptogams. They are the first evolved plant group with vascular tissue system for the conduction of water and food materials. Due to the presence of vascular tissue, they are called as Vascular Cryptogams. The term Pteridophyte is derived from two words Pteron meaning feather and phyton meaning plant. Thus, Pteridophytes are the plants with Feather-like leaves. Pteridophytes occupy the intermediate position between Bryophytes and Phanerogams (seed plants). The important characteristics of Pteridophytes are summarized below:. ...

A cryptogam (scientific name Cryptogamae) is a plant (in the wide sense of the word) that reproduces by spores, without flowers or seeds. Cryptogamae (Greek κρυπτός kryptos, hidden + γαμέω, gameein, to marry) means hidden reproduction, referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing plants. Other names, such as thallophytes, lower plants, and spore plants are also occasionally used. As a group, Cryptogamae are the opposite of the Phanerogamae (Greek φανερός, phaneros = visible) or Spermatophyta (Greek σπέρμα, sperma = seed and φυτόν, phyton = plant), the seed plants. The best-known groups of cryptogams are algae, lichens, mosses and ferns,[1] but it also includes non-photosynthetic organisms traditionally classified as plants, such as fungi, slime molds, and bacteria.[2]The classification is now deprecated in Linnaean taxonomy. At one time, the cryptogams were formally recognised as a group within ...

Robert Augustine (Biology). Small Ubiquitin-related Modifier (SUMO) is a post-translational modification that is rapidly attached to target proteins within minutes of exposure to heat, cold, and drought and acts to mitigates the damage inflicted by these stresses. SUMO appears to be under tight transcriptional control that prevents its hyper-accumulation, however the mechanism that regulates this homeostasis is unknown. This project aims to characterize this phenomenon in the moss Physcomitrella patens, and develop strategies to ascertain the factors(s) that mediate this response. This project will utilize molecular biology techniques, and there will be considerable latitude in developing strategies to identify the regulatory mechanism.. Prerequisites ...

Yay! We finally have our cousins blogging! George and Beverly, along with their children, are online. The blog was created to help family and friends continue to be updated on and pray for their daughter Delie, who was kicked by a horse a few weeks ago. Thankfully, she did not suffer any serious head or spinal injury but the accident did severely damage her eye. She is in the process of seeing multiple doctors to repair both the bone structure around her eye and well as to determine what can be done to restore as much sight as possible to her eye. Each night Little Philip thanks God for all of his cousins, naming each by name. ZeeZee is now pronounced correctly as Delie by Little Philip, thanks to recent extra bedtime prayers for our sweet cousin. And so, the other Moss Family can be found at http://mossfarm.blogspot.com/.

Studies on extracellular proteins (ECPs) contribute to understanding of the multifunctional nature of apoplast. Unlike vascular plants (tracheophytes), little information about ECPs is available from nonvascular plants, such as mosses (bryophytes). In this study, moss plants (Physcomitrella patens) were grown in liquid culture and treated with chitosan, a water-soluble form of chitin that occurs in cell walls of fungi and insects and elicits pathogen defense in plants. ECPs released to the culture medium were compared between chitosan-treated and nontreated control cultures using quantitative mass spectrometry (Orbitrap) and 2-DE-LC-MS/MS. Over 400 secreted proteins were detected, of which 70% were homologous to ECPs reported in tracheophyte secretomes. Bioinformatics analyses using SignalP and SecretomeP predicted classical signal peptides for secretion (37%) or leaderless secretion (27%) for most ECPs of P. patens, but secretion of the remaining proteins (36%) could not be predicted using
The Cell Biology chair group of Wageningen University & Research recently set up a research line using mosses in order to unravel biological processes in plants at a faster pace. This has now resulted in a scientific publication. Thanks to the research into Physcomitrella patens, we now know more about the formation of new cell walls during cell division.
The moss Physcomitrella patens as a model species provides an important reference for early-diverging lineages of plants and the release of the genome in 2008 opened the doors to genome-wide studies. The usability of a reference genome greatly depends on the quality of the annotation and the availability of centralized community resources. Therefore, in the light of accumulating evidence for missing genes, fragmentary gene structures, false annotations and a low rate of functional annotations on the original release, we decided to improve the moss genome annotation. Here, we report the complete moss genome re-annotation (designated V1.6) incorporating the increased transcript availability from a multitude of developmental stages and tissue types. We demonstrate the utility of the improved P. patens genome annotation for comparative genomics and new extensions to the cosmoss.org resource as a central repository for this plant
Different views have been proposed concerning the vegetative structure of the archaic bryophytic gametophyte.. The two main & diametrically opposed views are:. 1. The gametophyte ( in primitive stage) was nothing but an erect leafy plant.. 2. The gametophyte was a simple thallus-like structure. No differentiation was developed that time both internally & externally.. According to the first view,. the bryophytic gametophyte had performed a long jump to green algae.. Again, the second one is claiming that,. parenchymatous terrestrial green algae are presenting the initial point of such evolution.. As both of the views are somehow indicating the similar case, whatever it is upward or downward, we are now going to a comparative study.. - There seems no apparent relation between the antheridium and archaegonium of bryophytes and the antheridium and oogonium of algae. The superficial cells of bryophytes are developed into sterile jacket layer that is completely perceiving the fact of algae.. According ...
At noon, when I pulled into the driveway of The Moss Farm, in Raleigh, NC, the newspaper still sat by the curb. Moss does that to you; the news of the day can wait until solitude and serenity from the moss garden recharges your soul. Its best to begin the day with moss mellowing ones mood, making it more tolerable to read whats above the fold.. The air is warm as I enter the sun drenched front garden of The Moss Farm. Immediately, Im drawn to the moss garden on the side of the property. Rushed, yet focused on tasks at hand, I take a step into the moss garden and most of must-dos for my busy day, melts away. A mere step into the dappled shade from newly leafed trees, protecting the moss floor, and I am transformed. Moss is the only thing now on my mind.. I pause at this first step to take in the view. The design is such so the view is not taken in all at once. As I surveyed the scene, I heard the sound of music - tranquil music. I wondered if was playing as I walked up or did I somehow ...
THE exogenous(circumferential)growth of fossil vascular cryptogams is a subject of so much interest and importance, that I may perhaps be permitted to say a few words regarding it. In a paper which was read at the December meeting of the Edinburgh Botanical Society, I combated the idea of the circumferential growth of calamites. The moist nature of the soil in which calamites must have grown would lead one to expect a poor development of the fibro-vascular bundles, and in comparing what I believe to be the fibro-vascular bundles of calamites with those of our recent equisetums, this idea is fully confirmed. Then in Equisetum there is a large development of the sclerenchyma of Mettenius, which forms the strong hypoderma. In a Brazilian fern which has come under my notice, this sclerenchyma runs to the fibro-vascular bundles, and presents an appearance exactly like Williamsons woody wedges, the large and small cells giving an appearance wonderfully like medullary rays. There is another point which, to my
The familiar leafy moss plant is the sexual phase of the moss life cycle. When mature, most mosses develop sex organs . Some mosses have separate male and female plants, whereas others have male and female sex organs on the same plant. In wet conditions, sperm cells are released from male sex organs (antheridia) and swim to the female organs (archegonia), attracted by a chemical released by the female organ. If a sperm cell fertilises the egg cell embedded within the female organ, a spore-producing plant develops. This consists of a stalk with a spore capsule attached to the parent moss plant. As the spore capsule matures it releases its spores into the air, and then dies. If moss spores fall in a damp place, they germinate and grow into leafy moss plants, and the cycle is completed.. ...

Physcomitrella is also a model organism that is easily manipulated for study of how many plant genes function. Physcomitrella is to flowering plants what the fruit fly is to humans; that is, in the same way that the fly and mouse have informed animal biology, the genome of this moss will advance our exploration of plant genes and their functions and utility, said Joint Genome Institute director Eddy Rubin. Quatrano added that, unlike vascular plant systems, we can target and delete specific moss genes to study their function in important crop processes, and replace them with genes from crop plants to allow us to study the evolution of gene function. In addition to the genome, extensive genomic tools are now available in Physcomitrella to study comparative gene function and evolution as related to bioenergy and other processes of importance to crops. The availability of the Physcomitrella genome is expected to create important new opportunities for understanding the molecular mechanisms ...
Mosses were collected in October, 2005. Approximately, 7 cm2 of plants and soil were extracted from 10 different points scattered in the site. Samples were stored in hermetically sealed bags to preserve the humidity during the return to Antofagasta.. Treatment of mosses with cadmium. To induce the formation of phytochelants in moss plants, these were watered once daily with 100 µmoles/L of Cd (II), for a period of 12 days. Previous studies with different species of mosses demonstrated that this concentration of Cadmium increased the GSH pool signifcantly 11, 12. Plants were sprayed, since mosses absorb water through the cuticle.. Three samples of moss plants of 300 mg, were taken at day 0 (before watering with Cd), 4, 7 and 12 of exposition to the Cd solution according to the experimental design suggest by Bruns and col. 11. Moss plants were cut and washed four times with supra-pure water (distilled and deionized), after removal of dry stems and soil. Plants were allowed to dry on paper towels ...
