Anthocerotophyta: A plant division that includes hornworts, named for the horn-like appearance of the spore-producing plant (sporophyte).UrobilinBryophyta: A division of the plant kingdom. Bryophyta contains the subdivision, Musci, which contains the classes: Andreaeopsida, BRYOPSIDA, and SPHAGNOPSIDA.Hepatophyta: A plant division. They are simple plants that lack vascular tissue and possess rudimentary rootlike organs (rhizoids). Like MOSSES, liverworts have alternation of generations between haploid gamete-bearing forms (gametophytes) and diploid spore-bearing forms (sporophytes).Ferns: Seedless nonflowering plants of the class Filicinae. They reproduce by spores that appear as dots on the underside of feathery fronds. In earlier classifications the Pteridophyta included the club mosses, horsetails, ferns, and various fossil groups. In more recent classifications, pteridophytes and spermatophytes (seed-bearing plants) are classified in the Subkingdom Tracheobionta (also known as Tracheophyta).Embryophyta: Higher plants that live primarily in terrestrial habitats, although some are secondarily aquatic. Most obtain their energy from PHOTOSYNTHESIS. They comprise the vascular and non-vascular plants.Plants, Genetically Modified: PLANTS, or their progeny, whose GENOME has been altered by GENETIC ENGINEERING.Genome, Plastid: The genetic complement of PLASTIDS as represented in their DNA.Genome Size: The amount of DNA (or RNA) in one copy of a genome.Soil: The unconsolidated mineral or organic matter on the surface of the earth that serves as a natural medium for the growth of land plants.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject.

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.

The evolution of chloroplast RNA editing. (1/14)

RNA editing alters the nucleotide sequence of an RNA molecule so that it deviates from the sequence of its DNA template. Different RNA-editing systems are found in the major eukaryotic lineages, and these systems are thought to have evolved independently. In this study, we provide a detailed analysis of data on C-to-U editing sites in land plant chloroplasts and propose a model for the evolution of RNA editing in land plants. First, our data suggest that the limited RNA-editing system of seed plants and the much more extensive systems found in hornworts and ferns are of monophyletic origin. Further, although some eukaryotic editing systems appear to have evolved to regulate gene expression, or at least are now involved in gene regulation, there is no evidence that RNA editing plays a role in gene regulation in land plant chloroplasts. Instead, our results suggest that land plant chloroplast C-to-U RNA editing originated as a mechanism to generate variation at the RNA level, which could complement variation at the DNA level. Under this model, many of the original sites, particularly in seed plants, have been subsequently lost due to mutation at the DNA level, and the function of extant sites is merely to conserve certain codons. This is the first comprehensive model for the evolution of the chloroplast RNA-editing system of land plants and may also be applicable to the evolution of RNA editing in plant mitochondria.  (+info)

XET activity is found near sites of growth and cell elongation in bryophytes and some green algae: new insights into the evolution of primary cell wall elongation. (2/14)

BACKGROUND AND AIMS: In angiosperms xyloglucan endotransglucosylase (XET)/hydrolase (XTH) is involved in reorganization of the cell wall during growth and development. The location of oligo-xyloglucan transglucosylation activity and the presence of XTH expressed sequence tags (ESTs) in the earliest diverging extant plants, i.e. in bryophytes and algae, down to the Phaeophyta was examined. The results provide information on the presence of an XET growth mechanism in bryophytes and algae and contribute to the understanding of the evolution of cell wall elongation in general. METHODS: Representatives of the different plant lineages were pressed onto an XET test paper and assayed. XET or XET-related activity was visualized as the incorporation of fluorescent signal. The Physcomitrella genome database was screened for the presence of XTHs. In addition, using the 3' RACE technique searches were made for the presence of possible XTH ESTs in the Charophyta. KEY RESULTS: XET activity was found in the three major divisions of bryophytes at sites corresponding to growing regions. In the Physcomitrella genome two putative XTH-encoding cDNA sequences were identified that contain all domains crucial for XET activity. Furthermore, XET activity was located at the sites of growth in Chara (Charophyta) and Ulva (Chlorophyta) and a putative XTH ancestral enzyme in Chara was identified. No XET activity was identified in the Rhodophyta or Phaeophyta. CONCLUSIONS: XET activity was shown to be present in all major groups of green plants. These data suggest that an XET-related growth mechanism originated before the evolutionary divergence of the Chlorobionta and open new insights in the evolution of the mechanisms of primary cell wall expansion.  (+info)

Contribution of genosystematics to current concepts of phylogeny and classification of bryophytes. (3/14)

This paper is a survey of the current state of molecular studies on bryophyte phylogeny. Molecular data have greatly contributed to developing a phylogeny and classification of bryophytes. The previous traditional systems of classification based on morphological data are being significantly revised. New data of the authors are presented on phylogeny of Hypnales pleurocarpous mosses inferred from nucleotide sequence data of the nuclear DNA internal transcribed spacers ITS1-2 and the trnL-F region of the chloroplast genome.  (+info)

From the protonema grows the adult gametophyte, which is the persistent and independent stage in the life cycle. This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter, and several layers of cells in thickness. It is green or yellow-green from the chlorophyll in its cells, or bluish-green when colonies of cyanobacteria grow inside the plant.. When the gametophyte has grown to its adult size, it produces the sex organs of the hornwort. Most plants are monoicous, with both sex organs on the same plant, but some plants (even within the same species) are dioicous, with separate male and female gametophytes. The female organs are known as archegonia (singular archegonium) and the male organs are known as antheridia (singular antheridium). Both kinds of organs develop just below the surface of the plant and are only later exposed by disintegration of the overlying cells.. The biflagellate sperm must swim from the antheridia, or else be splashed ...

Southwest Asia is defined in the present work as all the land east of the Aegean and Mediterranean Seas to Afghanistan in the east, including the Sinai and Arabian Peninsulas and Socotra Island. This region is also known as the Near East, Vorderer Orient, Levant or Asia Minor and it essentially covers Asia 5 of Index Muscorum. Bryologically, southwest Asia is still poorly and unevenly studied, although its exploration began relatively early. The first note on mosses from the Arabian Peninsula appeared in 1775, in the report from the Danish expedition of Per Forska° l to Arabia Felix. Information on the bryoflora of southwest Asia has increased markedly since the middle of the nineteenth century thanks to the contributions of P. G. Lorentz, J. Juratzka, J. Milde, A. Geheeb, V. Schiffner, J. Baumgartner and others who studied bryophytes collected by the various travelers and explorers of this region. Nonetheless, so far the only more or less complete regional bryophyte floras in the Near East ...

Rochelle, a few months ago there was on this list an exchange of posts about this subject. In my opinion it is clear that some snails sold as apple or mystery snails do not eat plants normally, while others do it voraciously. I am not aware of any easy system to differentiate the two types on the basis of their morphology, although I suppose that different behavior corresponds to different species. After having had experience with 3-4 plant-eating snails, I recently ordered some "guaranteed" non plant-eating mystery snails for Carolina Biologic Supply, which indeed live happily with some hornwort with no problems. However, for those interested in those issues, I will not order anymore from that company because I later discovered that they import and supply to schools for dissection classes large quantities of cat carcasses. These cats are caught in less developed countries and killed by drowning them in barrels of water. Complaints were made to that company by animal rights associations, but ...

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, ...
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 ...
Mosses are Bryophytes, which are non-vascular plants. They evolved from liverworts: evidence from mitochondrial DNA suggests that this is the stem group from which mosses, hornworts and all other land plants evolved.[1]p75. Mosses do not have cells that move water like other plants- water must soak into them, like a sponge. A patch of moss is made of many tiny moss plants packed together so that they can hold water for as long as possible. They do not have roots, and could not get water from them if they did. Because they cannot find water, they live in two ways. They can live in places that are always wet; like near a spring, a river, or in a place where there is a lot of fog. They can also dry up when there is no moisture. This means they they can never live in dry places like deserts.. They cannot grow very large because they could not move water to the top of the moss. The largest moss grows in New Zealand, and is about 30 cm tall.. A moss does not make seeds. A moss does not have fruit. The ...

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

Existing biozonation schemes for the Niger Delta are mainly qualitative with zonal intervals too large to record subtle events. This has made it necessary to look for additional palynological events to enable recognition of shorter, more refined interval zones to improve stratigraphical definition. Hitherto unrecognised occurrence trends of palynomorphs were discovered and used to construct a new zonation scheme that can be applied in the offshore delta area. Late Miocene to Early Pleistocene sediments have been divided into five principal assemblage zones: FF1, Anthoceros abundance zone; FF2, Elaeis guineensis-Echiperiporites icacinoides zone; FF3, Lycopodium-Retibrevitricolporites obodoensis/protrudens zone; FF4, Cyperaceae abundance zone; and FF5, Echitriletes pliocenicus-Podocarpus milanjianus zone. The zones are further subdivided into 16 sub-zones based on quantitative events with some having finer subdivisions into (a) and (b). Examples of the zonations applied to three exploration wells ...

Xyloglucan transglycosylases (XETs) have been implicated in many aspects of cell wall biosynthesis, but their function in vascular tissues, in general, and in the formation of secondary walls, in particular, is less well understood. Using an in situ XET activity assay in poplar stems, we have demonstrated XET activity in xylem and phloem fibers at the stage of secondary wall formation. Immunolocalization of fucosylated xylogucan with CCRC-M1 antibodies showed that levels of this species increased at the border between the primary and secondary wall layers at the time of secondary wall deposition. Furthermore, one of the most abundant XET isoforms in secondary vascular tissues (PttXET16A) was cloned and immunolocalized to fibers at the stage of secondary wall formation. Together, these data strongly suggest that XET has a previously unreported role in restructuring primary walls at the time when secondary wall layers are deposited, probably creating and reinforcing the connections between the ...

Desertic areas are thought to be of no great interest for bryologists, but apparently the booklet shows the highly differentiated liverwort and moss flora of a great desertic and semi-desertic area, the Arabian Peninsula and Socotra. In 1980 from the Arabian Peninsula no bryophyte taxa was known. 1 hornwort, 50 liverwort and 178 moss species are now known from the area. This is due to a now twenty years investigation of the bryophyte flora. The booklet is a bryophyte flora of the area with a short overview on the bryofloristic exploration of the Arabian Peninsula and Socotra, a description of the phytochorial dements and a phytogeographical analysis. There are keys to all species, notes on the occurence of the species in the different countries and at the end there are given distribution maps.

Ferns and Fern Allies. The Bryophytes represent an evolutionary dead end and never achieved any great size since they lack a vascular system. A number of plant groups began the development of a vascular system yet were still dependent upon water to get their gametes together. These plants, known as tracheophytes, show many of the structural adaptations that were necessary for an independent life on land, yet most of these plant groups lacked the necessary combination of features to serve as the ancestoral form of the higher plants.. This group of plants includes the ferns and their allies the whisk fern, Psilotum, the club mosses, Lycopodium and the horsetails, Equisetum. See also A Photographic Atlas for the Biology Laboratory, 4th Edition, p.65,66,69. Note the life cycle of the fern at your on-line study guide noted above and at this site.

Bryological and Lichenological Section/ABLS. Mansouri, Katayoun [1]. Immunocytological analysis of callose in cell walls across generative apices and tissues of liverworts and mosses.. Geometrically distinct apical cells (lenticular, tetrahedral, hemidiscoid and cuneate) in gametophytes of bryophytes determine growth habits of these plants. All four types of apical cells are present in the morphologically diverse liverworts, while in mosses tetrahedral (technically obovoid) cells predominate. Leafy and thalloid growth forms of both mosses and liverworts are correlated with these geometries in a way that each apical derivative (merophyte) gives rise to an organ: leaf, leaf-like structure, portion of the stem and thallus. Immediate and successive divisions of the apical cell result in an arrangement of organs that follows the outline of the cutting faces of the apical cell. For example, tetrahedral cells in liverworts have three cutting faces from which three rows of leaves originate. Apical cells ...

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.

This study describes the phenology of sporophytes of the fern Dryopteris filix-mas in relation to whole plant development. Sterile and fertile potted sporophytes were set out at an exposed site and the seasonal development of the fronds was measured from the commencement of unfolding, through the phase of increasing length, up to discoloration. The physiological activity of the fronds was determined by measuring photosynthetic gas exchange. The fronds of sterile sporophytes unfolded in April, about a week earlier than those of fertile plants, but the colour had already begun to turn in September and their life span was 1-2 months shorter. However, between mid-June and the end of August the sterile sporophytes put out several sets of new fronds: these overwintered without changing color and were still photosynthetically active in the following spring. All types of fronds were fully expanded 1-2 months from the beginning of unfolding and, with a natural supply of CO2, had similar maximum net

The major classes of cells differentiate from undifferentiated meristematic cells (analogous to the stem cells of animals) to form the tissue structures of roots, stems, leaves, flowers and reproductive structures.. Xylem cells[15] are elongated cells with lignified secondary thickening of the cell walls. Xylem cells are specialised for conduction of water, and first appeared in plants during their transition to land in the Silurian period more than 425 million years ago (see Cooksonia). The possession of xylem defines the vascular plants or Tracheophytes. Xylem tracheids are pointed, elongated xylem cells, the simplest of which have continuous primary cell walls and lignified secondary wall thickenings in the form of rings, hoops or reticulate networks. More complex tracheids with valve-like perforations called bordered pits characterise the gymnosperms. The ferns and other pteridophytes and the gymnosperms only have xylem tracheids, while the angiosperms also have xylem vessels. Vessel members ...
Chlorophyta is a division of green algae, informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it refers to a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. Like the land plants (bryophytes and tracheophytes), green algae contain chlorophyll a... (Source: Wikipedia. Photo: (c) Alfredo Dorantes Euan, all rights reserved)

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 ...
Spike moss plants, or club moss, are not true mosses but very basic vascular plants. Can you grow spike moss? You certainly can, and it makes an excellent ground cover but needs consistent moisture to remain green. Learn more in this article.

Not included in the Oocystaceae by Liu et al., 2017: fig. 6. - (8 Sep 2017) - Wendy Guiry. Description: Filaments short, uniseriate enclosed by common mucilaginous sheath of variable thickness, without polarity and free-floating. Individual cells dispersed in loose linear arrangement, almost equidistant, or more usually cells united end to end in separate pairs. Space between pairs filled with mucilage. Cells cylindrical, containing parietal, plate-like chloroplast with(out?) pyrenoids and starch. Nucleus in median constriction of chloroplast. Vacuoles with conspicuous oil-globules marking cell poles. Vegetative propagation by fragmentation of filaments; method of sexual reproduction unknown. Planctonema planktonic in various freshwater habitats in Europe and Japan. Taxonomic position of Planctonema uncertain, with contradictory reports based on light microscopy, e.g., pyrenoid presence questionable and chloroplasts described as both axillary and parietal. In one isolate, however, ...

Living all over the world both in the wild and as decorative ground coverings in personal gardens Common Hair Cap Moss is easy to find. Preferring to live in lightly shaded areas with moist slightly acidic soil, it can also survive in areas of full sunlight provided the soil is moist (2). The Common Hair Cap Moss can also grow in areas of poor soil and slow drainage. These characteristics make this moss a good plant for all types of gardens and gardeners. In gardens of Japan, where mosses are used commonly, the Common Hair Cap Moss is used more than any other species combined. In the wild it grows in many places, from granite outcrops to the coastal plain to the banks of ponds or lakes. With the ability to grow in a diversity of habitats, Common Hair Cap Moss is seen all over the world. ...

The above illustration of Earths sea surface temperature was obtained from two weeks of infrared observations by the Advanced Very High Resolution Radiometer (AVHRR), an instrument on board NOAA-7 during July 1984. Temperatures are color coded with red being warmest and decreasing through oranges, yellows, greens, and blues. Temperature patterns seen in this image are the result of many influences, including the circulation of the ocean, surface winds, and solar heating. The image indicates a large pool of warm water in the Western Pacific and a tongue of relatively cold water extending along the Equator westward from South America. Every few years, there occurs an interrelated set of changes in the global atmospheric and oceanic circulation known as an El Nino in which the region of warm equatorial water in the West extends eastward across the Pacific and blankets the cool, productive regions along the coast of South America. Fish, birds, and marine mammals that depend upon the normally ...
