Abstract:
Gametophytic population density influences sex expression in the fern Ceratopteris Brongn. Extensive variation occurs among gametophyte families, both in the response of sex expression to density and in the covariate (density) adjusted frequency of hermaphroditic gametophytes. These differences are probably a function of genetic variability in the antheridiogen mediation of sex expression. In general, the frequency of hermaphroditic gametophytes decreases and becomes asymptotic and more stable with increased density. Higher gametophytic densities probably promote maleness through the more rapid attainment of effective concentrations of antheridiogen. Environmental factors that modify sex expression, e.g., gametophytic density and the response of any given gametophytic family to density, may ultimately influence the mating system.

Abstract:
The haploid gametophytes of the fern Ceratopteris richardii are autotrophic and develop independently of the diploid sporophyte plant. While haploid genetics is useful for screening and characterizing mutations affecting gametophyte development in Ceratopteris, it is difficult to assess whether a gametophytic mutation is dominant or recessive or to determine allelism by complementation analysis in a haploid organism. This report describes how apospory can be used to produce genetically marked polyploid sporophytes whose gametophyte progeny are heterozygous for mutations affecting sex determination in the gametophyte and a known recessive mutation affecting the phenotype of both the gametophyte and sporophyte. The segregation ratios of wild-type to mutant phenotypes in the gametophyte progeny of polyploid sporophyte plants indicate that all of the mutations examined are recessive. The presence of many multivalents and few univalents in meiotic chromosome preparations of spore mother cells confirm that the sporophyte plants assayed are polyploid. The DNA content of the sperm of their progeny gametophytes was also found to be approximately twice that of sperm from wild-type haploid gametophytes.

Abstract:
The sporophyte–gametophyte interface in cultured Lycopodium appressum gametophytes consists of a sporophytic foot embedded in gametophyte tissue. Foot cells and contiguous gametophytic cells develop extensive wall ingrowths, making them transfer cells. Transfer cells in the foot of young sporophytes and in adjacent gametophyte cells have elongated, narrow wall ingrowths forming a labrynthine wall–membrane apparatus, numerous mitochondria, and plastids with variable amounts of starch. Transfer cells in older interfaces have thickened wall ingrowths, few mitochondria, plastids with numerous plastoglobuli and little starch, and a large central vacuole. Plasmodesmata do not develop between cells of sporophyte and gametophyte generations and these are, therefore, isolated symplastically during all stages of sporophyte development. Key words: Lycopodium, foot, haustorium, transfer cells, ultrastructure.

Abstract:
Abstract The maturation of male and female gametophytes together with its impact on plant sexual reproduction has not received much attention, and the molecular mechanisms underlying the process are largely unknown. Here, we show that Arabidopsis DEAD-box RNA helicase 29 (RH29) is critical for the functional maturation of both male and female gametophytes. Homozygous rh29 mutants could not be obtained, and heterozygous mutant plants were semi-sterile. Progression of the cell cycle in rh29 female gametophytes was delayed. Delayed pollination experiments showed that rh29 female gametophytes underwent cell-fate specification but were unable to develop into functional gametophytes. Functional specification but not morphogenesis was also disrupted in rh29 male gametophytes, causing defective pollen tube growth in the pistil. RH29 was highly and specifically expressed in gametophytic cells. RH29 shares high amino acid sequence identity with yeast Dbp10p, which partially rescues the aborted-ovules phenotype of rh29/RH29 plants. RH29 is essential for the synthesis of REGULATORY PARTICLE TRIPLE A ATPase 5a (RPT5a), a subunit of the regulatory particle of the 26S proteasome. Our results suggest that gametophyte functional maturation is a necessary process for successful fertilization and that RH29 is essential for the functional maturation of both male and female gametophytes.

Abstract:
Plant architecture is determined by cell division and growth, thus simulation models describing these processes are ideal for determining how local development produces the overall plant form. Because fern gametophytes are structurally simple, they are ideal for investigating the effects of cellular growth and division on plant form. In this work we examine the gametophytic development of Schizaea pusilla Pursh., a small, bog-adapted fern whose gametophyte forms as a mass of single-celled filaments. Using light and scanning electron microscopy we made detailed observations of gametophyte development to generate data for a simulation mechanical model of S. pusilla gametophyte development. To examine how plant architecture is an emergent property of cell division, we constructed a simulation model expressed using the formalism of L-systems. While developing a model of growth in this fern we discovered a previously undescribed structure that contributes to the architecture of this plant, which we term knots. We document the development of knots and demonstrate how they contribute to the overall plant architecture.

Abstract:
Sexual reproduction in plants, unlike that of animals, requires the action of multicellular haploid gametophytes. The male gametophyte (pollen tube) is guided to a female gametophyte through diploid sporophytic cells in the pistil. While interactions between the pollen tube and diploid cells have been described, little is known about the intercellular recognition systems between the pollen tube and the female gametophyte. In particular, the mechanisms that enable only one pollen tube to interact with each female gametophyte, thereby preventing polysperm, are not understood. We isolated female gametophyte mutants named magatama (maa) from Arabidopsis thaliana by screening for siliques containing half the normal number of mature seeds. In maa1 and maa3 mutants, in which the development of the female gametophyte was delayed, pollen tube guidance was affected. Pollen tubes were directed to mutant female gametophytes, but they lost their way just before entering the micropyle and elongated in random directions. Moreover, the mutant female gametophytes attracted two pollen tubes at a high frequency. To explain the interaction between gametophytes, we propose a monogamy model in which a female gametophyte emits two attractants and prevents polyspermy. This prevention process by the female gametophyte could increase a plant's inclusive fitness by facilitating the fertilization of sibling female gametophytes. In addition, repulsion between pollen tubes might help prevent polyspermy. The reproductive isolations observed in interspecific crosses in Brassicaceae are also consistent with the monogamy model.

Abstract:
The morphology and pigment contents of sporophytes and gametophytes of ten fern species were studied. In the morphological study, variations were found in stipe, texture, rachis, fronds and sori of these species. Photosynthestic pigment contents of sporophyte and gametophyte of ten species vary to a great extent. Even sporophyte and gametophyte of same species vary in pigment content. Sporophyte revealed higher chlorophyll content than gametophyte. The highest chlorophyll a and b were found in the gametophyte of Cetarach officinarum Gametophyte of Adiantum flabellatum produced maximum anthocyanin whereas minimum anthocyanin content was found in the sporophyte of Cetarach dalhousiae. The highest carotenoid content was obtained from the gametophyte of Cheilanthus albomarginata. Altitudinal variations were also found to affect morphology and pigment content of sporophytes and gametophytes of ten fern species.

Full text
Abstract:
SynopsisLow temperature SEM of juvenile leaves of Pteridium aquilinum (L.) Kuhn revealed that outgrowths arise from leaf cells as soon as three days after their detachment from the plant. Such outgrowths matured into fully functional gametophytes, so it can be said that the phase change from sporophyte to gametophyte occurred during the three day interval between detachment and outgrowth protrusion. Measurement of the incorporation of tritiated uridine into leaves detached for 0–5 days indicated that RNA levels rise during the first two days of culture and subsequently decline. The significance of this finding is discussed in relation to theories concerning changes in phase, in particular the suggestion that RNA connected with sporophytic growth must be expunged and that concerned with gametophytic growth synthesised during phase change.

Full text
Abstract:
Gametophytes of Tmesipteris lanceolata Dang., which are mycorrhizal in nature, were grown in axenic culture. If cultured in the light on a nutrient medium containing minerals and 0.5% glucose, they did not become photosynthetic; however, about 15% of them produced apogamous sporophytes with stems and microphylls. The gametophyte–sporophyte junction had a direct connection between the gametophyte and sporophyte tissues and lacked a foot, which is typical for apogamy. Gametangia were limited to the gametophyte portions of these gametophyte–sporophyte growths, and the vascular tissue was present only in the sporophyte regions. The apogamous aerial stems had the normal anatomy for a sporophyte, with vascular tissue, epidermal cells, stomata, and chlorenchyma. The origin of the apogamous sporophytes was different from the origin in fern gametophytes. The Tmesipteris sporophytes arose terminally from the gametophyte apices. It appears that the apical meristem of the gametophyte is converted to a shoot apical meristem to form the apogamous aerial shoot.Key words: Tmesipteris, Psilotaceae, apogamy, sporophyte, gametophyte.

Abstract:
Ferns have conspicuous sporophytes as the dominant phase in their life cycle; however, the gametophytes are completely separated from the sporophytes and supply their own nutrition, unlike in bryophytes and seed plants. Among the gametophytes, some maintain their populations in the gametophyte phase without progressing to sporophyte production and are known as independent gametophytes. Independent gametophytes of Antrophyum obovatum Baker were recently reported in one population on Jeju Island, Korea. In the present study, we surveyed more places to find new independent gametophyte populations of A. obovatum using the rbcL gene sequence-based DNA barcoding technique. We identified two new sites inhabited by independent gametophytes. Archegonia and juvenile sporophytes were independently observed in each location under slightly different environmental conditions. Consequently, in the case of this species, functional sporophyte production is likely suppressed by prezygotic and postzygotic sterility, depending on microenvironmental factors.

Abstract:
Gametophytic selection was examined as a breeding tool in developing Phalaenopsis hybrids that are more cool or warm temperature tolerant. Two hybrid Phalaenopsis, P. (Taisoco Windian à Sogo Sogo Yukidian) by P. hybrid unknown, were reciprocally cross-pollinated and exposed to 14°C/9°C for 7 days as a cold pollination treatment. Plants were pollinated again and exposed to 30°C/25°C for 3 days for the warm pollination treatment. Each cultivar was placed in either of two growth chambers during the pollination treatments and exposed to the selected temperatures, an 11-h photoperiod with an irradiance of 180 Mmol⠢m-2⠢s-1 and a relative humidity of 70%. The plants were returned to the greenhouse after pollination and the green capsules were collected after 150 days. Seeds obtained from these treatments were surface-sterilized and equal volumes were placed on Phytamax® medium. Evaluation of protocorm development was done after 73 days on a thermogradient table ranging from 10 to 30ºC. For the first family for which reciprocal crosses were available, the number of protocorms per plate ranged from 0 in the coldest treatments to 290 at 28°C. For cold pollinated seeds, protocorm development was optimum at 22 and 28°C (means of 290 and 250 protocorms per plate, respectively) whereas the greatest protocorm development for warm pollinated seeds occurred at 20°C (103 protocorms per plate). Of the 1471 total protocorms obtained 1095 were from cold pollinations, whereas 376 were from the warm pollinations. Protocorms were evaluated for leaf and root formation 125 days after initial plating. Transfer to warm or cold incubators occurred as protocorms developed leaves and roots. Seedlings were finally transferred to dried sphagnum and placed in growth chambers set to original pollination temperatures. One year after initial plating seedlings were evaluated on the following criteria: wet weight, number of leaves, leaf area, number of roots, and root length. The pollination treatment significantly affected the number of roots per seedling whereas germination temperature during germination significantly affected the weight (g). Weight of the seedlings, number of roots and the average root length were significantly affected by the interaction between pollination treatment and germination temperature. The weight, number of leaves, and average root length were significantly affected by the interaction between pollination treatment and incubator/growth chamber. These differences indicated that seedlings derived from warm pollination were more vigorous under warm growing conditions and those derived from cold pollination were more vigorous under cold growing conditions. The significance of the interaction between pollination treatment and incubator/growth chamber indicates that gametophytic selection for thermotolerance in Phalaenopsis can be successfully used as a plant breeding tool. Additional replication is required to confirm the greater germinability of seed derived from pollination occurring over a greater range of temperatures.

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.

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:
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.
