Global expression profiling applied to the analysis of Arabidopsis stamen development

ABSTRACT: To obtain detailed information about gene expression during stamen development in Arabidopsis thaliana, we compared, by microarray analysis, the gene expression profile of wild-type inflorescences to those of the floral mutants apetala3, sporocyteless/nozzle, and male sterile 1, in which different aspects of stamen formation are disrupted. These experiments led to the identification of groups of genes with predicted expression at early, intermediate and late stages of stamen development. Additional experiments aimed at characterizing gene expression specifically during microspore formation. To this end, we compared the gene expression profiles of wild-type flowers of distinct developmental stages to those of the male sterile 1 mutant. Computational analysis of the datasets derived from this experiment led to the identification of genes that are likely involved in the control of key developmental processes during microsporogenesis. Keywords: mutant comparison, developmental series

Transcriptional regulators of stamen development in Arabidopsis identified by transcriptional profiling

Project description:In Arabidopsis, jasmonate is required for stamen and pollen maturation. Mutants deficient in jasmonate synthesis, such as opr3, are male-sterile but become fertile when jasmonate is applied to developing flower buds. We have used ATH1 oligonucleotide arrays to follow gene expression in opr3 stamens for 22 hours following jasmonate treatment. In these experiments, a total of 821 genes were specifically induced by jasmonate and 480 repressed. Comparisons with data from previous studies indicate that these genes constitute a stamen-specific jasmonate transcriptome, with a large proportion (70%) of the genes expressed in the sporophytic tissue but not in the pollen. Bioinformatics tools allowed us to associate many of the induced genes with metabolic pathways that are likely up-regulated during jasmonate-induced maturation. Our pathway analysis led to the identification of specific genes within larger families of homologues that apparently encode stamen-specific isozymes. Extensive additional analysis of our dataset identified 13 transcription factors that may be key regulators of the stamen maturation processes triggered by jasmonate. Two of these transcription factors, MYB21 and MYB24, are the only members of subgroup 19 of the R2R3 family of MYB proteins. A myb21 mutant obtained by reverse genetics exhibited shorter anther filaments, delayed anther dehiscence and greatly reduced male fertility. A myb24 mutant was phenotypically wild type, but production of a myb21 myb24 double mutant indicated that introduction of the myb24 mutation exacerbated all three aspects of the myb21 phenotype. Exogenous jasmonate could not restore fertility to myb21 or myb21 myb24 mutant plants. Together with the data from transcriptional profiling, these results indicate that MYB21 and MYB24 are induced by jasmonate and mediate important aspects of the jasmonate response during stamen development.

Gene expression profiling for early rice stamen

Project description:Plant organ formation, or organogenesis is the process in which the primordium derived from shoot apical meristem develops into an organ with a given shape and proper function, through a series of cell division and differentiation. To decipher the genetic program underling plant organ formation, we targeted early rice stamen development that covers most important events in male organ formation and germ cell initiation in plants. Totally, seven samples were used in this experiment. Stamens of stages 2-6 was collected through microdissection under microscope. And to ensure the stamen primordia collected are at corresponding stages, rice panicles were cut in half longitudinally, one half for paraffin sectioning to confirm developmental stages and the other half for preparing GEP samples. Samples of primordial and just-expanded third leaves were used as controls because leaf and stamen are homolog organs. RNA was extracted and amplified with Two-Cycle Eukaryotic Target Labeling Assay kit, and then hybridized to microarrays. Three biological replicates were applied for each sample.

Stamen Development in Tomato - Jasmonates Control Ethylene Action in Timing of Pollen Maturation, Anther Dehiscence and Pollen Release

Project description:Jasmonates are well known signaling components required for diverse processes ranging from wound and pathogen responses to regulation of developmental processes. A prominent feature of jasmonate biosynthesis or signaling mutants is the loss of fertility. In contrast to the male sterile phenotype of Arabidopsis mutants, the loss of the co-receptor protein COI1 in the tomato mutant jai1-1 results in female sterility with additional severe effects on stamen and pollen development. While a general model of jasmonate effects on male gametophyte development has been proposed to involve the regulation of water transport, the molecular details of this response are scarce. Here we show an extensive temporal profiling of the development, hormone content, transcriptome and metabolome of tomato stamen in six distinct stages of flower development in wild type and jai1-1. We found that the premature stamen desiccation of jai1-1 stamens and the preponed pollen maturation coincide with an accumulation of desiccation-related metabolites. The wild type shows a transient increase of jasmonates up to mid-flowering that is absent in jai1-1. This finding coincides with an early increase of the ethylene precursor ACC in jai1-1 that is similarly reflected in the increased expression of ethylene biosynthesis and response genes. Our data suggests an essential role of jasmonates in the temporal inhibition of ethylene production to prevent premature desiccation of stamens and to ensure proper timing in flower development.

Transcriptome Profile Analysis Reveals the Regulation Mechanism of Stamen Abortion in Handeliodendron bodinieri（Levl.）Rehd

Project description:To elucidate the molecular mechanism of stamen abortion underlying sex differentiation from transcriptomic aspects in Handeliodendron bodinieri, we use abnormal stamens before and after abortion in female flowers and normal stamen in male flowers at the same stage as control material. Key genes regulating stamen abortion was identified by using RNA-seq technique. The results show that it was abortion science stage 6 during anther development, at the same time, HbGPAT, HbAMS, HbLAP5, HbLAP3 and HbTES were down-regulated , and HbML5 was up-regulated. Therefore, these information will provide theoretical foundation for the conservation, breeding, scientific research and application of Handeliodendron bodinieri.

Exploring the genes associated with male sterility mutant (msm) in Chinese cabbage (Brassica campestris ssp. pekinensis) using RNA-Seq

Project description:The hybrid seed production was performed using the male sterility line, which is an important way of heterosis utilization in Chinese cabbage. A stably inherited male sterile mutant msm was obtained from a Chinese cabbage DH line ‘FT’ using the isolated microspore culture combined with 60Co γ-rays mutagenesis. Compared to the wild type ‘FT’, the msm exhibited completely degenerated stamens and no pollen phenotype, and other characters had no significant difference except for stamen. The genetic analysis indicated that the msm mutant phenotype was controlled by a single recessive nuclear gene. Cytological observation showed that the stamen abortion of msm began at the tetrad period, and tapetum cells were abnormally expanded and highly vacuolated, leading to microspore abortion. Comparative transcriptome analysis on the flower buds of ‘FT’ and msm using RNA-Seq technology revealed a total of 1,653 differentially expressed genes (DEGs). Among which, a large number of genes associated with male sterility were found, including 64 pollen development and pollen tube growth-related genes, 94 pollen wall development-related genes, 11 phytohormone-related genes and 16 transcription factor-related genes, and the overwhelming majority of these genes were down-regulated in the msm vs. ‘FT’ comparison. Furthermore, KEGG pathway analysis indicated that a variety of carbohydrate metabolic and lipid metabolic pathways were significantly enriched, which may be related to pollen abortion. The expression patterns of 24 male sterility-related genes were analyzed using qRT-PCR. In addition, a total of 24,476 single nucleotide polymorphisms and 413,073 insertion-deletion events were specifically detected in msm. These results facilitate to elucidate the regulatory mechanisms of male sterility in Chinese cabbage.

Heat-induced proteomes in tomato pollen mother cells

Project description:Tomato pollen production and viability is highly vulnerable to higher temperature. Hot summers with temperature reaching above 32°C can disrupt production of viable pollens and fruit set, resulting in yield loss. In recent years, temperature above 35-38oC has become a norm during mid-summer with potential adverse impacts on the production of tomatoes and many other crop species. Pollens are developed through the microsporogenesis and micro-gametogenesis stages. The most heat sensitive period is from the meiotic process of the microsporocytes, at the young microspore stage (uninucleate stage of microspore) to during late pollen development (pollen mitosis). This project studied the heat-induced proteomes in microsporocyte, also called pollen mother cells (PMC). Homogenous PMC samples were collected from cross-sectioned frozen fresh anther tissues of tomato ‘Maxifort’ using laser capture microdissection (LCM). Tandem mass tag (TMT) proteomics analysis was conducted to identify proteomics changes related to heat tolerance during pollen development.
