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.

Particle bombardment mediated transformation and GFP expression in the moss Physcomitrella patens. (1/279)

There are few plants facilitated for the study of development, morphogenesis and gene expression at the cellular level. The moss Physcomitrella patens can be a very useful plant with several advantages: simple life cycle containing a major haploid gametophyte stage, easy manipulation, small genome size (6 x 10(8) bp) and high similarities with higher plants. To establish the transformation system of mosses as a model for basic plant research, a series of experiments were performed. Mosses were cultured in cellophane overlaid BCD media, transformed by particle bombardment and selected by the choice of appropriate antibiotics. Initial transformants appeared 8 d or 14 d after selection, showing different sensitivities toward the antibiotics used. Heat treatment during the preparation of particles revealed that denaturing the DNA enabled a more efficient way to deliver a transgene into the chromosome. This was proven by the increase in the number of transformants by five times in the plants with denatured DNA. In the test for the repairing capacity of mosses, 154 and 195 transformants survived from 1 d and 3 d incubations, respectively, indicating that a longer period of incubation seemed to be recommendable for better survival. The selected transformants were further analyzed at the DNA and expression level. Transformed genes were confirmed by PCR where all the transformants showed the expected size of amplification. Histochemical beta-glucuronidase (GUS) and green fluorescent protein (GFP) expression also confirmed the integration of exogenous DNA. In a comparison of the two different forms of GFP, soluble-modified GFP (smGFP) expressed stronger signals than modified GFP (mGFP) due to its improved solubility. Confirmation of the transgene in the chloroplast transformation has improved the applicability of moss as a model system for the study of basic biological researches.  (+info)

The diversification of plant cytosolic small heat shock proteins preceded the divergence of mosses. (2/279)

A cDNA library was constructed with mRNA isolated from heat-stressed cell cultures of Funaria hygrometrica (Bryophyta, Musci, Funariaceae). cDNA clones encoding six cytosolic small heat shock proteins (sHSPs) were identified using differential screening. Phylogenetic analysis of these sHSP sequences with other known sHSPs identified them as members of the previously described higher plant cytosolic class I and II families. Four of the F. hygrometrica sHSPs are members of the cytosolic class I family, and the other two are members of the cytosolic class II family. The presence of members of the cytosolic I and II sHSP families in a bryophyte indicates that these gene families are ancient, and evolved at least 450 MYA. This result also indicates that the plant sHSP gene families duplicated much earlier than did the well-studied phytochrome gene family. Members of the cytosolic I and II sHSP families are developmentally regulated in seeds and flowers in higher plants. Our findings show that the two cytosolic sHSP families evolved before the appearance of these specialized structures. Previous analysis of angiosperm sHSPs had identified class- or family-specific amino acid consensus regions and determined that rate heterogeneity exists among the different sHSP families. The analysis of the F. hygrometrica sHSP sequences reveals patterns and rates of evolution distinct from those seen among angiosperm sHSPs. Some, but not all, of the amino acid consensus regions identified in seed plants are conserved in the F. hygrometrica sHSPs. Taken together, the results of this study illuminate the evolution of the sHSP gene families and illustrate the importance of including representatives of basal land plant lineages in plant molecular evolutionary studies.  (+info)

Multiubiquitin chain binding subunit MCB1 (RPN10) of the 26S proteasome is essential for developmental progression in Physcomitrella patens. (3/279)

The 26S proteasome, a multisubunit complex, is the primary protease of the ubiquitin-mediated proteolytic system in eukaryotes. We have recently characterized MCB1 (RPN10), a subunit of the 26S complex that has affinity for multiubiquitin chains in vitro and as a result may function as a receptor for ubiquitinated substrates. To define the role of MCB1 further, we analyzed its function in Physcomitrella patens by generating MCB1 gene disruptions using homologous recombination. PpMCB1, which is 50 to 75% similar to orthologs from other eukaryotes, is present in the 26S proteasome complex and has a similar affinity for multiubiquitin chains, using a conserved hydrophobic domain within the C-terminal half of the polypeptide. Unlike yeast Deltamcb1 strains, which grow normally, P. patens Deltamcb1 strains are viable but are under developmental arrest, generating abnormal caulonema that are unable to form buds and gametophores. Treatment with auxin and cytokinin restored bud formation and subsequent partial development of gametophores. Complementation of a Deltamcb1 strain with mutated versions of PpMCB1 revealed that the multiubiquitin chain binding site is not essential for the wild-type phenotype. These results show that MCB1 has an important function in the 26S proteasome of higher order eukaryotes in addition to its ability to bind multiubiquitin chains, and they provide further support for a role of the ubiquitin/26S proteasome proteolytic pathway in plant developmental processes triggered by hormones.  (+info)

Molecular phylogenetic analysis among bryophytes and tracheophytes based on combined data of plastid coded genes and the 18S rRNA gene. (4/279)

The basal relationship of bryophytes and tracheophytes is problematic in land plant phylogeny. In addition to cladistic analyses of morphological data, molecular phylogenetic analyses of the nuclear small-subunit ribosomal RNA gene and the plastic gene rbcL have been performed, but no confident conclusions have been reached. Using the maximum-likelihood (ML) method, we analyzed 4,563 bp of aligned sequences from plastid protein-coding genes and 1,680 bp from the nuclear 18S rRNA gene. In the ML tree of deduced amino acid sequences of the plastid genes, hornworts were basal among the land plants, while mosses and liverworts each formed a clade and were sister to each other. Total-evidence evaluation of rRNA data and plastid protein-coding genes by TOTALML had an almost identical result.  (+info)

Isolation of a germin-like protein with manganese superoxide dismutase activity from cells of a moss, Barbula unguiculata. (5/279)

A novel extracellular Mn-superoxide dismutase (SOD) was isolated from a moss, Barbula unguiculata. The SOD was a glycoprotein; the apparent molecular mass of its native form was 120 kDa, as estimated by gel filtration chromatography, and that of its monomer was 22,072 Da, as estimated by time of flight mass spectroscopy. The protein had manganese with a stoichiometry of 0.80 Mn/monomer. The cDNA clone for a gene encoding the extracellular Mn-SOD was isolated. Sequence analysis showed that it has a strong similarity to germin (oxalate oxidase) and germin-like proteins (GLPs) of several plant species and possesses all the characteristic features of members of the germin family. The clone encoding this extracellular Mn-SOD was therefore designated B. unguiculata GLP (BuGLP). BuGLP had no oxalate oxidase activity. In addition, the cDNA for a gene encoding the moss mitochondrial Mn-SOD was isolated. Its amino acid sequence had little similarity to that of BuGLP, even though a close similarity was observed among the mitochondrial Mn-SODs of various organisms. BuGLP was the first germin-like protein that was really demonstrated to be a metalloprotein with Mn-SOD activity but no oxalate oxidase activity.  (+info)

Tagged mutagenesis and gene-trap in the moss, Physcomitrella patens by shuttle mutagenesis. (6/279)

The moss, Physcomitrella patens has been used as a useful material in many fields, because of its simple body plan, ease of gene targeting, and other reasons. Although many mutants have been reported, no method to isolate the corresponding genes was reported. We developed a gene tagging and gene-trap system in P. patens by using the shuttle mutagenesis technique, which has been used in the budding yeast. In 5264 tagged lines, 203 mutants with altered developmental or morphological phenotypes were obtained. In 129 of 4757 gene-trap lines, beta-glucuronidase (GUS) activity was detected in some tissue. Although multiple copies of a tag were detected in many tagged lines by Southern analyses, most copies are likely integrated at the same locus according to PCR analyses.  (+info)

A bifunctional delta-fatty acyl acetylenase/desaturase from the moss Ceratodon purpureus. A new member of the cytochrome b5 superfamily. (7/279)

Many plant genes have been cloned that encode regioselective desaturases catalyzing the formation of cis-unsaturated fatty acids. However, very few genes have been cloned that encode enzymes catalyzing the formation of the functional groups found in unusual fatty acids (e.g. hydroxy, epoxy or acetylenic fatty acids). Here, we describe the characterization of an acetylenase from the moss Ceratodon purpureus with a regioselectivity differing from the previously described Delta12-acetylenase. The gene encoding this protein, together with a Delta6-desaturase, was cloned by a PCR-based approach with primers derived from conserved regions in Delta5-, Delta6-fatty-acid desaturases and Delta8-sphingolipid desaturases. The proteins that are encoded by the two cloned cDNAs are likely to consist of a N-terminal extension of unknown function, a cytochrome b5-domain, and a C-terminal domain that is similar to acyl lipid desaturases with characteristic histidine boxes. The proteins were highly homologous in sequence to the Delta6-desaturase from the moss Physcomitrella patens. When these two cDNAs were expressed in Saccharomyces cerevisiae, both transgenic yeast cultures desaturated Delta9-unsaturated C16- and C18-fatty acids by inserting an additional Delta6cis-double bond. One of these transgenic yeast clones was also able to introduce a Delta6-triple bond into gamma-linolenic and stearidonic acid. This resulted in the formation of 9,12,15-(Z,Z,Z)-octadecatrien-6-ynoic acid, the main fatty acid found in C. pupureus. These results demonstrate that the Delta6-acetylenase from C. pupureus is a bifunctional enzyme, which can introduce a Delta6cis-double bond into 9,12,(15)-C18-polyenoic acids as well as converting a Delta6cis-double bond to a Delta6-triple bond.  (+info)

The translational apparatus of Tortula ruralis: polysomal retention of transcripts encoding the ribosomal proteins RPS14, RPS16 and RPL23 in desiccated and rehydrated gametophytes. (8/279)

Tortula ruralis (Syntrichia ruralis) is an important model system for the study of plant vegetative desiccation tolerance. One of the most intriguing aspects of desiccation-tolerant plants is the maintenance of key cellular components in stable and viable forms in the desiccated state, particularly those related to the translational apparatus (i.e. ribosomes and ribosomal RNAs). This study investigated the third integral component of the translational apparatus, the ribosomal proteins. Three T. ruralis cDNAs encoding predicted polypeptides with significant similarity to ribosomal proteins were isolated from a cDNA expression library derived from the polysomal, messenger ribonucleoprotein particle (mRNP) fraction of desiccated gametophytes; Rps14 and Rps16 encode the small-subunit ribosomal proteins RPS14 and RPS16, respectively, and Rpl23 encodes the large-subunit ribosomal protein RPL23. RPS14, RPS16 and RPL23, the deduced polypeptides, have predicted molecular masses of 14.4 kDa, 16.2 kDa and 14.9 kDa and predicted pI's of 11.08, 10.34 and 10. 67, respectively. Phylogenetic analysis of the deduced amino acid sequences demonstrated that each of the T. ruralis proteins is most similar to ribosomal proteins from higher plants even though RPS14 and RPL23 show high divergence from their other plant counterparts. RNA blot hybridizations of RNAs present within the polysomal mRNP fraction (i.e. the 100 Kxg pellet) demonstrated that Rps14, Rps16 and Rpl23 are expressed in moss gametophytes during a desiccation-rehydration cycle and, according to the prior cDNA classification scheme in T. ruralis, are constitutive clones. These findings clearly demonstrated that Rps14, Rps16 and Rpl23 transcripts are retained within the polysomal fractions of desiccated gametophytes.  (+info)

During the work for this thesis cellular and molecular approaches were used to study photomorphogenesis in the mosses Ceratodon purpureus and Physcomitrella patens. Phycocyanobilin, which substitutes for the phytochrome chromophore phytochromobilin, was injected into protonema tip cells of aphototropic Ceratodon mutants. This led in ~70 % of the filaments to a clear phototropic response and elevated chlorophyll levels in red light. The studies implied the existence of an extreme stable subfraction of holophytochrome, localized apparently to the apex of the tip cell. Injections of expression plasmids carrying for heme oxygenase genes from rat, Arabidopsis and Ceratodon (CpHO1) indicate that the mutants lack the enzymic activity of this gene product. In ~40 % injected filaments the wildtype phenotype could be restored. A GFP-CpHO1 fusion protein expressed from an appropriate plasmid showed that the enzyme is localized to the plastids. However, both plastidic and cytosolic enzymes were able to ...

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 ...

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
Institut fur Pflanzengenetik und Kulturpflanzenforschung (IPK), Corrensstr. 3, D-06466 Gatersleben, Germany. A complex mixture of fatty acid-derived aldehydes, ketones, and alcohols is released upon wounding of the moss Physcomitrella patens. To investigate the formation of these oxylipins at the molecular level we isolated a lipoxygenase from P. patens, which was identified in an EST library by sequence homology to lipoxygenases from plants. Sequence analysis of the cDNA showed that it exhibits a domain structure similar to that of type2 lipoxygenases from plants, harboring an N-terminal import signal for chloroplasts. The recombinant protein was identified as arachidonate 12-lipoxygenase and linoleate 13-lipoxygenase with a preference for arachidonic acid and eicosapentaenoic acid. In contrast to any other lipoxygenase cloned so far, this enzyme exhibited in addition an unusual high hydroperoxidase and also a fatty acid chain-cleaving lyase activity. Because of these unique features the pronounced
Strigolactones are a novel class of plant hormones controlling shoot branching in seed plants. They also signal host root proximity during symbiotic and parasitic interactions. To gain a better understanding of the origin of strigolactone functions, we characterised a moss mutant strongly affected in strigolactone biosynthesis following deletion of the CAROTENOID CLEAVAGE DIOXYGENASE 8 (CCD8) gene. Here, we show that wild-type Physcomitrella patens produces and releases strigolactones into the medium where they control branching of protonemal filaments and colony extension. We further show that Ppccd8 mutant colonies fail to sense the proximity of neighbouring colonies, which in wild-type plants causes the arrest of colony extension. The mutant phenotype is rescued when grown in the proximity of wild-type colonies, by exogenous supply of synthetic strigolactones or by ectopic expression of seed plant CCD8. Thus, our data demonstrate for the first time that Bryophytes (P. patens) produce ...
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 ...
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.
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 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 ...
Background MicroRNAs (miRNAs) are regulatory RNA molecules that are specified by their mode of action, the structure of primary transcripts, and their typical size of 20C24 nucleotides. experimental-computational approach, we report on the identification of 48 novel miRNAs and their putative targets in the moss Physcomitrella patens. From these, 18 miRNAs and two targets were verified in independent experiments. As a result of our study, the number of known miRNAs in Physcomitrella has been raised to 78. Functional assignments to mRNAs targeted by these miRNAs revealed a bias towards genes that are involved in regulation, cell wall biosynthesis and defense. Eight miRNAs were detected with different expression in protonema and gametophore tissue. The miRNAs 1C50 and 2C51 are located on a shared precursor that are separated by only one nucleotide and become processed in a tissue-specific way. Conclusion Our data provide evidence for a surprisingly diverse and complex miRNA population in ...
Results] Recombinant Ppα-DOX protein catalyzed the conversion of fatty acids into 2-hydroperoxy derivatives with a substrate preference for α-linolenic, linoleic and palmitic acids. Ppα-DOX is expressed during development in tips of young protonemal filaments with maximum expression levels in mitotically active undifferentiated apical cells. In leafy gametophores, Ppα-DOX is expressed in auxin producing tissues, including rhizoid and axillary hairs. Ppα-DOX transcript levels and Ppα-DOX activity increased in moss tissues infected with Botrytis cinerea or treated with Pectobacterium carotovorum elicitors. In B. cinerea infected leaves, Ppα-DOX-GUS proteins accumulated in cells surrounding infected cells, suggesting a protective mechanism. Targeted disruption of Ppα-DOX did not cause a visible developmental alteration and did not compromise the defense response. However, overexpressing Ppα-DOX, or incubating wild-type tissues with Ppα-DOX-derived oxylipins, principally the aldehyde ...

His team had previously discovered that the moss Physcomitrella patens is more robust, as loss of ATE function affects development and energy storage but does not result in moss plants dying. Although the N-end rule pathway of protein degradation was discovered in 1986, it was unclear which proteins are flagged by ATE in plants.. For their current study the team from the Plant Biotechnology department of the University of Freiburg co-operated with Professor Andreas Schlosser and his group from the Rudolf Virchow Center for Experimental Biomedicine of the University of Würzburg.. Together, they developed novel methods in immuno-precipitation and mass spectrometry of arginylated proteins and found five needles in the haystack: After analysing about thirty thousand protein spectra the scientists identified four specific proteins that are flagged by ATE and a small heat shock protein that may act as a molecular chaperone to support ATE function. Our results provide mechanistic insights into the ...

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 ...
The COP1/SPA complex of Arabidopsis is a well-characterized key negative regulator that actively suppresses the light signaling cascade in dark-grown plants by ubiquitinating transcription factors which mediate the various light responses. The E3 ubiquitin ligase activity is conserved in the mammalian ortholog of COP1 which, however, appears to function without a need for SPA proteins since SPA genes appear to be specific to plants. SPA protein sequences are distinct from COP1 in that they carry a kinase-like domain in the N-terminus [13, 26]. This kinase-like domain is conserved in Physcomitrella, rice and Arabidopsis SPA proteins and shows a similar divergence in sequence from bona fide Ser/Thr kinase motifs in all three species. This finding suggests on one hand that this kinase-like domain is of functional importance - though its exact role has so far remained elusive [31, 32, 34, 53] - and on the other hand that early in land plant evolution this domain was already divergent in sequence ...

Mosses survive climate catastrophes. Press release on a paper recently published in New Phytologist Insights from the cold transcriptome of Physcomitrella patens: global specialization pattern of conserved transcriptional regulators and identification of
The draft genome of the moss model, Physcomitrella patens, comprised approximately 2000 unordered scaffolds. In order to enable analyses of genome structure and evolution we generated a chromosome-scale genome assembly using genetic linkage as well as (end) sequencing of long DNA fragments. We find that 57% of the genome comprises transposable elements (TEs), some of which may be actively transposing during the life cycle. Unlike in flowering plant genomes, gene- and TE-rich regions show an overall even distribution along the chromosomes. However, the chromosomes are mono-centric with peaks of a class of Copia elements potentially coinciding with centromeres. Gene body methylation is evident in 5.7% of the protein-coding genes, typically coinciding with low GC and low expression. Some giant virus insertions are transcriptionally active and might protect gametes from viral infection via siRNA mediated silencing. Structure-based detection methods show that the genome evolved via two rounds of ...
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 ...
Structural and functional basis of cellulose synthesis. Using Physcomitrella patens and other organisms as model systems, we are learning how plants make cellulose for building new cell wall. The studies use methods of molecular biology and cryoEM to characterize the enzyme as a monomer, and when it assembles into its larger Cellulose Synthase Complex (CSC for short).

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.. ...

Biotechnology: In close cooperation with industrial partners we initiated functional genomics of Physcomitrella, identifying novel genes relevant to metabolic engineering and to abiotic stresses such as drought, salt and cold. Such moss genes are being directly transferred to crop plants to improve their performance. Transgenic Physcomitrella can be grown photoautotrophically in bioreactors. We work on the production of pharmaceutically relevant proteins in such cultures in co-operation with the university spin-off company greenovation Biotech, Freiburg. In addition to these successful industrial co-operations we are ready to establish new partnerships. As a university group our work is primarily science-driven. However, we strongly feel that our basic work is paid by tax-money and we, therefore, have the responsibility to transfer applicable know-how swiftly to the market ...

Ammonium and urea are important nitrogen sources for autotrophic organisms. Plant genomes encode several families of specific transporters for these molecules, plus other uptake mechanisms such as aquaporins and ABC transporters. Selaginella and Physcomitrella are representatives of lycophytes and bryophytes, respectively, and the recent completion of their genome sequences provided us with an opportunity for comparative genome studies, with special emphasis on the adaptive processes that accompanied the conquest of dry land and the evolution of a vascular system. Our phylogenetic analysis revealed that the number of genes encoding urea transporters underwent a progressive reduction during evolution, eventually down to a single copy in vascular plants. Conversely, no clear evolutionary pattern was found for ammonium transporters, and their number and distribution in families varies between species. In particular Selaginella, similar to rice, favors the AMT2/MEP family of ammonium transporters over the

Plant-derived terpenoids are extensively used in perfume, food, cosmetic and pharmaceutical industries, and several attempts are being made to produce terpenes in heterologous hosts. Native hosts have evolved to accumulate large quantities of terpenes in specialized cells. However, heterologous cells lack the capacity needed to produce and store high amounts of non-native terpenes, leading to reduced growth and loss of volatile terpenes by evaporation. Here, we describe how to direct the sesquiterpene patchoulol production into cytoplasmic lipid droplets (LDs) in Physcomitrium patens (syn. Physcomitrella patens), by attaching patchoulol synthase (PTS) to proteins linked to plant LD biogenesis. Three different LD-proteins: Oleosin (PpOLE1), Lipid Droplet Associated Protein (AtLDAP1) and Seipin (PpSeipin325) were tested as anchors. Ectopic expression of PTS increased the number and size of LDs, implying an unknown mechanism between heterologous terpene production and LD biogenesis. The expression of PTS

The major risk associated with moss is its ability to make surfaces very slippery. Paths, car parks, decking, patios, walkways, pavements and outdoor communal areas can become hazardous when infected by moss. When left unchecked, moss growth is capable of negatively affecting a businesss operations. The presence of moss in dynamic areas can cause difficulties with manoeuvring across premises, and increases the likelihood of slips and trips, putting the well-being of personnel at risk.. In addition to causing a slip hazard, moss can hamper water flow and prevent water from draining away quickly, especially during flooding. This is due to its ability to absorb liquid. Although flooding does happen in urban areas, moss that is located in wooded areas, fields and bogs is often a cause of preventing flood water from receding. This in turn can impact upon developed areas such as roads, pathways and other structures.. Moss growth on signage can also prove a significant risk. If motorists are unable to ...
Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses. Robin Wall Kimmerers book is not an identification guide, nor is it a scientific treatise. Rather, it is a series of linked personal essays that will lead general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings, from salmon and hummingbirds to redwoods and rednecks. Kimmerer clearly and artfully explains the biology of mosses, while at the same time reflecting on what these fascinating organisms have to teach us. Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ...

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.

The bryophyte and vascular plant lineages diverged ,400 million years ago (Gifford and Foster, 1989). Since that time, developmental mechanisms have diversified such that distinct lineages exhibit diverse morphologies. Comparative studies have suggested that the P. patens and Arabidopsis genomes contain largely similar sets of genes (Nishiyama et al., 2003). However, it is unknown how many of these common genes are regulated similarly in the different developmental contexts of the two organisms. The work described here presents an example of a regulatory pathway that is conserved between these two divergent species. In both P. patens and Arabidopsis, GLK function is required for correct thylakoid stacking within the chloroplast and for the accumulation of both chlorophyll and LHCB. As such, it is likely that GLK gene function was required for chloroplast development in the last common ancestor of bryophytes and flowering plants. Therefore, GLK-mediated regulation of chloroplast development ...

Randy Moss didnt make the kind of impact that everyone envisioned when the Vikings traded for him Oct. 6. In four games he caught 13 passes for 174 yards and two touchdowns.. He had one vintage Moss catch, a 37-yard touchdown against the New York Jets in his first game back with the team. But he didnt give the offense that vertical passing option that they envisioned when they brought him back.. However, theres no denying Moss opened the middle of the field for Percy Harvin on underneath routes and also helped the running game. Look at how the Patriots defended Moss the entire game Sunday.. Safety Brandon Meriweather lined up 20-25 yards deep on Moss side every play, all but eliminating his vertical speed. But that created room for Harvin and others to work the middle of the field. With Moss no longer part of the equation, the wide receiver corps again lacks that vertical threat.. That should change in a few weeks when Sidney Rice returns from hip surgery.

It is the basal sterile part of the capsule composed of parenchymatous cells. In comparison to other hair-cup-mosses (e.g., Polytrichum) it is indistinct in Pogonatum. In the centre conducting strand is present which is continuous with seta and columella. (b) Theca: It is the fertile portion of the capsule (Fig. 10 B-D)). The longitudinal section passing through the region shows the outermost single layer epidermis which lacks stomata. It is followed by two two four celled thick chlorophylls tissue. It is traversed by the filaments of chlorophyll containing cells called trabaeculae. One end of the trabaeculae is connected with the chlorophyllose tissue and the other with the outer wall of the spore sac (Fig. 10 B). The spore sac is also surrounded on inner side by an inner air sac. It is also traversed by ...
