Abstract:
Pogonatum urnigerum (Polytrichaceae) in vitro culture was established from spores collected in nature. Both protonema and gametophore stages of gametophyte development were obtained. Also, a stable callus culture was established using hormone-free nutrient medium. The best nutrient medium for development was half-strength Murashige- Skoog medium supplemented with 1.5% sucrose. Auxin treatment enabled some gametophores to develop, but prolonged treatment induced early senescence. Tissues grown on cytokinin did not produce any gametophytes and did not survive prolonged treatment.

Abstract:
Changes in RNase activity similar to those accompanying cytokinin-induced formation of gametophore buds in mosses (a decrease in the early phase of bud formation and later an increase in enzyme activity) have also been found during spontaneous formation of gametophores in moss ontogenesis. Using various factors affecting the cytokinin-induced process of bud formation a correlation has been found between this process and the increase in RNase activity.

Abstract:
Abstract Convergent evolution of shoot development across plant lineages has prompted numerous comparative genetic studies. Though functional conservation of gene networks governing flowering plant shoot development has been explored in bryophyte gametophore development, the role of bryophyte-specific genes remains unknown. Previously, we have reported Tnt1 insertional mutants of moss defective in gametophore development. Here, we report a mutant (short-leaf; shlf) having two-fold shorter leaves, reduced apical dominance, and low plasmodesmata frequency. UHPLC-MS/MS-based auxin quantification and analysis of soybean (Glycine max) auxin-responsive promoter (GH3:GUS) lines exhibited a striking differential auxin distribution pattern in the mutant gametophore. Whole-genome sequencing and functional characterization of candidate genes revealed that a novel bryophyte-specific gene (SHORT-LEAF; SHLF) is responsible for the shlf phenotype. SHLF represents a unique family of near-perfect tandem direct repeat (TDR)-containing proteins conserved only among mosses and liverworts, as evident from our phylogenetic analysis. Cross-complementation with a Marchantia homolog partially recovered the shlf phenotype, indicating possible functional specialization. The distinctive structure (longest known TDRs), absence of any known conserved domain, localization in the endoplasmic reticulum, and proteolytic cleavage pattern of SHLF imply its function in bryophyte-specific cellular mechanisms. This makes SHLF a potential candidate to study gametophore development and evolutionary adaptations of early land plants.

Abstract:
Many factors may affect the survival and establishment of a moss’s vegetative propagules after dispersal, but little is known about the species-specific nature of the response. This study examined the survival and regeneration of gametophore fragments after exposure to temperature changes for three boreal forest mosses from different habitats: Dicranum polysetum, Orthotrichum obtusifolium, and Pleurozium schreberi. Fragments were cultured on water agar and the survival and regeneration responses were recorded. Logistic regression analyses and AIC modeling evaluated the association between the response with the size of the gametophore fragments exposed to five abrupt or gradual temperatures for up to six exposure durations. The increased survival and regeneration was best explained when species were exposed to gradual, rather than abrupt temperatures; lower, rather than higher temperatures; and when the fragments had larger, rather than smaller sizes. The mosses had different survival and regeneration responses that may be species-specific, including clonal growth via the production of gametophore branches and protonemata, or mostly protonemata, even when exposed to elevated temperatures.

Abstract:
Stem cells self-renew and produce precursor cells that differentiate to become specialized cell types. Land plants generate several types of stem cells that give rise to most organs of the plant body and whose characters determine the body organization. The moss Physcomitrella patens forms eight types of stem cells throughout its life cycle. Under gametangium-inducing conditions, multiple antheridium apical stem cells are formed at the tip of the gametophore and each antheridium apical stem cell divides to form an antheridium. We found that the gametophore apical stem cell, which typically forms leaf and stem tissues, changes to become a new type of stem cell, which we term the antheridium initial stem cell. This antheridium initial stem cell produces multiple antheridium apical stem cells, resulting in a cluster of antheridia at the tip of gametophore. This is the first report of a land plant stem cell directly producing another type of stem cell during normal development. Notably, the antheridium apical stem cells are distally produced from the antheridium initial stem cell, similar to the root cap stem cells of vascular plants, suggesting the use of similar molecular mechanisms and a possible evolutionary relationship. This article is part of a discussion meeting issue ‘The Rhynie cherts: our earliest terrestrial ecosystem revisited’.

Abstract:
This study provides the results of the developmental biology of the highly rare and endangered moss species Bruchia vogesiaca (recorded in less than 30 localities in the Northern Hemisphere, mainly western, central, and southwestern Europe). The aim of the study was to achieve the fully developed gametophyte and to propagate it for the purpose of conservation, reintroduction, and introduction to potential habitats free from xenic contamination. These gametophytes will be used for the study of genetics and genomics of this species. The micropropagation of B. vogesiaca was successfully applied on BCD medium supplemented with 0.1 μM BA and on BCD supplemented with 0.3 μM IBA and 0.3 μM BA for numerous gametophore production. The highest production of secondary protonema was achieved on MS/2 S/2 medium enriched with 0.1 or 0.3 μM IBA and 0.3 μM BA. Rather successfully applied micropropagation of this threatened moss species enables better knowledge of its biology and is of great value for its conservation biology and developmental research. Chemical names used: indole-3-butyric acid (IBA), N6-benzyladenine (BA), Murashige and Skoog medium (MS).

Abstract:
In the protonema of <em>Ceratodon purpureus</em> (Hedw.) Brid., apical parts of the protonemal filaments (apical cells, initials of protonemal side branches and of gametophore buds) proved to be preferential sites of [<sup>14</sup>C]-leucine incorporation into proteins. In some filaments, a similar preference for [<sup>3</sup>H]-uridine incorporation into RNA was observed, whereas in others there was a rather uniform distribution of label over all cells. A short (0.5-2 h) treatment with cytokinin (N<sup>6</sup>-2-isopentenyladenine) enhanced [<sup>14</sup>C]-leucine incorporation, without changing the relative distribution of label. No such enhancement, as well as no change in label distribution could be observed in [<sup>3</sup>H]-uridine incorporation. No direct relationship seems to exist between the early promotion of protein synthesis by cytokinin in the protonema and cytokinin induction of gametophore buds.

Full text
Abstract:
Anandamide (NAE 20:4) or arachidonlyethanolamine (AEA) is the most widely studied N-acylethanolamine (NAE) because it mediates several physiological functions in mammals. In vascular plants, 12-18C NAEs inhibit growth in an abscisic acid (ABA)-dependent and -independent manner. Anandamide, which is unique to bryophyte Physcomitrella patens, inhibited gametophyte growth and reduced chlorophyll content when applied exogenously. It is hypothesized that anandamide mediates its responses through morphological and cellular changes. Following growth inhibition by short-term anandamide-treatment, microscopic analyses revealed relocated chloroplasts and depolymerized F-actin in protonemal tips. Long-term treatment showed partially bleached gametophyte cells with degraded and browning chloroplasts. These anandamide-mediated responses have physiological implications as AEA may function as a signal for gametophytes to activate secondary dormancy as seen with ABA. Future studies will investigate the role of AEA in mediating stress responses and possible interaction with ABA.

Abstract:
Investigations were carried out to determine the feasibility of a transposon tagging experiment in flax, Linum usitatissimum. The excision of the maize transposable element Activator (Ac) from the genome of transgenic flax callus was demonstrated, whilst a Dissociation element (Ds) was found to be stable. However, reintegration of excised Ac elements was not detected, and this barrier to gene tagging led to an examination of procedures which might improve the general applicability of transposon tagging. A recombinant Ac transposase gene was constructed in order to achieve a high germinal transposition frequency in transgenic plants; this feature is an essential component of an efficient transposon tagging strategy. The Ac construct was produced by fusing the promoter of an anther-specific gene to the transposase coding region. The anther-specific gene, APG, was cloned from Arabidopsis thaliana, following the identification of four putative microspore-specific mRNAs from Brassica napus. Of these mRNAs, one, termed 13, was analysed in detail and found to encode a novel oleosin protein, and was apparently confined to developing pollen. The I3 cDNA was used as a molecular probe to clone the APG gene, which encodes a proline-rich protein of unknown function. A small gene family encoding proteins with high sequence similarity to the APG protein was identified in B. napus via the isolation of three cDNAs termed CEX1, CEX2 and CEX6. Promoter fragments of the APG gene were demonstrated to drive expression of a ?-glucuronidase reporter gene in the male gametophyte, tapetum, stomium and anther wall of Nicotiana tabacum and Arahidopsis during the microspore development stage of gametogenesis. The restriction of transposition to these cells would permit the production of a seed population containing a wide range of unique transposon inserts which would be stable in during vegetative growth. Such applications of the APG/Ac fusion are discussed.

Abstract:
Plants have developed intricate mechanisms to control growth in response to a variety of environmental cues, to compensate its immobility and to survive in both normal and adverse conditions. The TCP proteins are a family of plant-specific, basic helix-loop-helix (bHLH) transcription factors that involve in different aspects in plant growth and developmental control. The Arabidopsis TCP20 has been shown to involve in coordinating cell growth and proliferation, and in growth arrest in response to DNA double-stranded breaks (DSB). In this thesis, the main interest is to examine the function of Arabidopsis TCP6, which shares the highest homology with TCP20, and like TCP20, contains a putative ATM phosphorylation motif that suggests potential involvement in the ATM/ATR-mediated DSB responses. Expressional analysis including transcript measurement and reporter gene tagging demonstrated that TCP6 is expressed in flowers, in particular in the first mitotic event of pollen and ovule/embryo sac development, indicating that TCP6 potentially involves in regulating the mitotic cell cycle during gametophyte development. Yet no gametophytic or fertility-affecting mutant phenotype was observed in the tcp6 single and tcp6/tcp20 double mutants, which may be due to high functional redundancy. The tcp6/tcp20 double mutant seedlings exhibited significantly higher growth performances in true leaf growth compared to wild type when treated with gamma radiation, implying that both functional TCP6 and TCP20 are involved in response to gamma radiation-generated DSBs. The work of this thesis provides the first expressional and functional characterizations of TCP6, with the results suggesting that TCP6 and other class I TCPs play a role in regulating growth under both normal and stress conditions.

Full text
Abstract:
BACKGROUND:In flowering plants, the female gametophyte is typically a seven-celled structure with four cell types: the egg cell, the central cell, the synergid cells, and the antipodal cells. These cells perform essential functions required for double fertilization and early seed development. Differentiation of these distinct cell types likely involves coordinated changes in gene expression regulated by transcription factors. Therefore, understanding female gametophyte cell differentiation and function will require dissection of the gene regulatory networks operating in each of the cell types. These efforts have been hampered because few transcription factor genes expressed in the female gametophyte have been identified. To identify such genes, we undertook a large-scale differential expression screen followed by promoter-fusion analysis to detect transcription-factor genes transcribed in the Arabidopsis female gametophyte.RESULTS:Using quantitative reverse-transcriptase PCR, we analyzed 1,482 Arabidopsis transcription-factor genes and identified 26 genes exhibiting reduced mRNA levels in determinate infertile 1 mutant ovaries, which lack female gametophytes, relative to ovaries containing female gametophytes. Spatial patterns of gene transcription within the mature female gametophyte were identified for 17 transcription-factor genes using promoter-fusion analysis. Of these, ten genes were predominantly expressed in a single cell type of the female gametophyte including the egg cell, central cell and the antipodal cells whereas the remaining seven genes were expressed in two or more cell types. After fertilization, 12 genes were transcriptionally active in the developing embryo and/or endosperm.CONCLUSIONS:We have shown that our quantitative reverse-transcriptase PCR differential-expression screen is sufficiently sensitive to detect transcription-factor genes transcribed in the female gametophyte. Most of the genes identified in this study have not been reported previously as being expressed in the female gametophyte. Therefore, they might represent novel regulators and provide entry points for reverse genetic and molecular approaches to uncover the gene regulatory networks underlying female gametophyte development.

Abstract:
La plupart des organismes eucaryotes se reproduisent sexuellement et ont des cycles de vie qui impliquent une alternance entre les phases haploïde et diploïde en raison de deux processus fondamentaux : la division cellulaire méiotique (à la transition diploïde-haploïde) et la fusion gamète ou syngamie (transition haploïde-diploïde). Dans les organismes photosynthétiques ayant des cycles de vie haploïde-diploïde, ces alternances sont entre deux générations multicellulaires distinctes : gamétophyte et sporophyte. Comme les générations de gamétophytes et de sporophytes sont construites à partir d'informations provenant d'un génome commun, il s'ensuit que les processus de régulation épigénétique doivent fonctionner à la fois pendant la méiose et pendant la syngamie pour déclencher le déclenchement du programme de développement approprié associé à chaque génération. L'analyse génétique de l'alternance du cycle de vie chez les organismes se répartissant de diverses façons sur les lignées de l'arbre eucaryote permettra d'améliorer notre compréhension au niveau moléculaire. Les connaissances actuelles indiquent que l'alternance du cycle de vie est régulée par des facteurs génétiques (facteurs de transcription du domaine homéodésique) et par des modifications chromatiniennes. La majorité des algues brunes ont un cycle de vie haploïde-diploïde et l'une de ces espèces, l'algue brune filamenteuse Ectocarpus, est utilisée comme système modèle pour étudier la régulation du cycle biologique. L'ectocarpe a un cycle de vie complexe. Les travaux actuels ont montré que l'alternance des générations d'Ectocarpus est contrôlée par deux facteurs de transcription homéodomaine, ORO et SAM, qui régulent l'induction du programme de développement sporophyte. Cependant, l'alternance entre le gamétophyte et le sporophyte peut également être régulée par un facteur sporophyte autonome non cellulaire sécrété dans le milieu de culture par les sporophytes. Ce facteur diffusible provoque une reprogrammation majeure du développement des cellules initiales (méio-spores) du gamétophyte. Il est intéressant de noter que les travaux actuels montrent que le BGC et la SAM peuvent faire partie du réseau de réglementation déclenché par le facteur sporophyte inducteur. Cependant, la nature biochimique de ce facteur n'est pas connue. L'objectif principal de cette thèse était de caractériser le facteur diffusible sporophyte inducteur. Les travaux ont porté sur l'optimisation de la production, du stockage et du dosage biologique du facteur et sur l'obtention d'informations sur sa nature biochimique. L'étude a également examiné la relation entre le facteur sporophyte inducteur et deux régulateurs génétiques, ORO et SAM, pour comprendre la voie de développement déclenchée par le facteur. En plus de ce travail sur l'identité de génération du cycle de vie, la thèse portait sur la caractérisation du mutant sans fondement, qui présente un phénotype similaire à celui du mutant distag et qui est affecté dans la formation de modèles de développement à la fois pendant les générations gamétophytes et sporophytes
Most eukaryotic organisms reproduce sexually and have life cycles that involve an alternation between haploid and diploid phases due to two fundamental processes meiotic cell division (at the diploid-to-haploid transition) and gametes fusion or syngamy (haploid-to-diploid transition). In photosynthetic organisms with haploid-diploid life cycles, these alternations are between two distinct multicellular generations: gametophyte and sporophyte. As both the gametophyte and sporophyte generations are constructed using information from a shared genome, it follows that epigenetic regulation processes must operate both during meiosis and during syngamy to trigger the initiation of the appropriate developmental program associated with each generation. Genetic analysis of life cycle alternation in organisms diversely distribute across the lineages of the eukaryotic tree will improve our understanding at the molecular level. Current knowledge indicates that life cycle alternation is regulated by genetic factors (homeodomain transcription factors) and by chromatin modifications. The majority of brown algae have haploid-diploid life cycle and one of these species, the filamentous brown alga Ectocarpus, is being used as a model system to study life cycle regulation. Ectocarpus has a complex life cycle. Current work has shown that alternation of generations in Ectocarpus is controlled by two homeodomain transcription factors, ORO and SAM, which regulate the induction of the sporophyte developmental program. However, alternation between the gametophyte and the sporophyte can also be regulated by a non-cell autonomous, sporophyte-inducing factor secreted into the culture media by sporophytes. This diffusible factor causes major developmental reprogramming in initial cells (meio-spores) of the gametophyte. Interestingly, current work shows that ORO and SAM may be part of the regulatory network triggered by the sporophyte-inducing factor. However, the biochemical nature of this factor is not known. The main objective of this thesis was to characterize the diffusible sporophyte-inducing factor. The work focused on optimizing production, storage and bioassay of the factor and on obtaining information about its biochemical nature. The study also investigated the relationship between the sporophyte-inducing factor and two genetic regulators, ORO and SAM, to understand the developmental pathway triggered by the factor. In addition to this work on life cycle generation identity, the thesis involved characterisation of the baseless mutant, which exhibits a similar phenotype to the distag mutant and is affected in developmental patterning during both the gametophyte and sporophyte generations

Abstract:
BACKGROUND:Because of their phylogenetic position and unique characteristics of their biology and life cycle, ferns represent an important lineage for studying the evolution of land plants. Large and complex genomes in ferns combined with the absence of economically important species have been a barrier to the development of genomic resources. However, high throughput sequencing technologies are now being widely applied to non-model species. We leveraged the Roche 454 GS-FLX Titanium pyrosequencing platform in sequencing the gametophyte transcriptome of bracken fern (Pteridium aquilinum) to develop genomic resources for evolutionary studies.RESULTS:681,722 quality and adapter trimmed reads totaling 254 Mbp were assembled de novo into 56,256 unique sequences (i.e. unigenes) with a mean length of 547.2 bp and a total assembly size of 30.8 Mbp with an average read-depth coverage of 7.0x. We estimate that 87% of the complete transcriptome has been sequenced and that all transcripts have been tagged. 61.8% of the unigenes had blastx hits in the NCBI nr protein database, representing 22,596 unique best hits. The longest open reading frame in 52.2% of the unigenes had positive domain matches in InterProScan searches. We assigned 46.2% of the unigenes with a GO functional annotation and 16.0% with an enzyme code annotation. Enzyme codes were used to retrieve and color KEGG pathway maps. A comparative genomics approach revealed a substantial proportion of genes expressed in bracken gametophytes to be shared across the genomes of Arabidopsis, Selaginella and Physcomitrella, and identified a substantial number of potentially novel fern genes. By comparing the list of Arabidopsis genes identified by blast with a list of gametophyte-specific Arabidopsis genes taken from the literature, we identified a set of potentially conserved gametophyte specific genes. We screened unigenes for repetitive sequences to identify 548 potentially-amplifiable simple sequence repeat loci and 689 expressed transposable elements.CONCLUSIONS:This study is the first comprehensive transcriptome analysis for a fern and represents an important scientific resource for comparative evolutionary and functional genomics studies in land plants. We demonstrate the utility of high-throughput sequencing of a normalized cDNA library for de novo transcriptome characterization and gene discovery in a non-model plant.

Abstract:
Research objective: to identify tomato genotypes resistant to Alternaria on variability and symptoms of male gametophyte on selective backgrounds with cultural filtrate of pathogens Alternaria spp. A set of gamete breeding techniques and genetic-statistical analysis were used in the experiments. Some patterns of the variability and heritability of traits in the tomato male gametophyte have been identified on media with filtrates of pathogens. The differences in the resistance of pollen to the filtrate influence were established; the differentiation and selection of genotypes for further breeding were made. These studies can be used at different stages of the selection process.
