Seed development in flowering plants is initiated after a double fertilization event with two sperm cells fertilizing two female gametes, the egg cell and the central cell, leading to the formation of embryo and endosperm, respectively. In most species the endosperm is a polyploid tissue inheriting two maternal genomes and one paternal genome. As a consequence of this particular genomic configuration the endosperm is a dosage sensitive tissue, and changes in the ratio of maternal to paternal con ...[more]

Project description:Little is known of the transcriptome of in vivo-grown pollen tubes, due to the difficulty of collection of pollen tubes elongating within the maternal gynoecium.We obtained the mRNAs undergoing translation (the translatome) of in vivo-grown pollen tubes from self-pollinated gynoecia of Arabidopsis thaliana(Col-0). Transgenic Arabidopsis plants (LAT52-HF-RPL18) harboring an epitope tagged ribosomal protein L18 driven by the pollen specific promoter (ProLAT52) were used for mRNA-ribosome complex isolation. After collection of polyribosomal (polysomal) complexes from self-pollinated (in vivo), unpollinated styles (buds), and in vitro-cultured pollen tubes, the actively translated mRNAs (the translatome) were purified, amplified to antisense RNA (aRNA). These aRNAs were hybridized to microarrays.Three independent biological replicates samples of aRNA from Bud, in vivo, and in vitro polysomal mRNA (translatomes) were hybridized to GeneChips to produce CEL files.

Project description:Seed development is dependent on a well-orchestrated interplay between different transcriptional programs operating in the embryo, the endosperm and the maternally derived seed coat. In angiosperms, the embryo and the endosperm are products of double fertilization during which the two pollen sperm cells fuse with the egg cell and the central cell of the female gametophyte. In Arabidopsis, mutation of the cell cycle regulator CYCLIN DEPENDENT KINASE A;1 (CKDA;1) results in pollen that only successfully fertilizes the egg cell. Seeds generated from crosses with cdka;1 pollen develop endosperm with solely maternal and no paternal contribution. Here we have exploited cdka;1 fertilization as a novel tool for genomic dissection of parental effects during seed development. We have generated genome-wide transcription profiles of cdka;1 fertilized seeds. By this approach, we identified 11 differentially expressed AGAMOUS-LIKE (AGL) genes encoding Type-I MADS-box transcription factors. Here, AGL36 was chosen for an in-depth study. We show that AGL36 is imprinted and only expressed from the maternal genome. In addition, we demonstrate that AGL36 imprinting is controlled by the activity of METHYLTRANSFERASE1 (MET1) maintenance DNA methyltransferase and DEMETER (DME) DNA glycosylase. Interestingly, our data also show that the active maternal allele of AGL36 is regulated throughout endosperm development by components of the FIS Polycomb Repressive Complex 2 (PRC2). These findings shed novel light on the interplay between maternal and paternal genomes in the seed and how imprinting is coordinated by different mechanisms. 3 biological replicates, each consisting of 35 siliques from 10 individual plants, were used. Arabidopsis thaliana wild type (ecotype Colombia-0 and Ler-0) and cdka;1 mutant (At3g48750 /SALK_109806) were sown out on soil and grown under the following conditions: 18oC day and 18oC night, 16 hr day length with 30 min adjustment of light to on and off, and 85 μmol/m2/sek in light intensity. For each replica, 10 Ler plants were emasculated and pollinated after 48 hours, either with individual WT Col or with individual cdka;1 mutant pollen. Three days after pollination (3 DAP), the siliques of each biological replicate were dissected with hypodermic needles to remove carpel walls, the pistil with pollen attached to it and the pedicel with abcsission zone. The remaining seeds attached to the middle lamella were harvested in bulk in liquid nitrogen at the same time of the day. Biological replicas are dye-swapped between slides.

Project description:Flowering plants have immotile sperm that develop within pollen and must be carried to female gametes by a pollen tube. The pollen tube engages in molecular interactions with several cell types within the pistil and these interactions are essential for successful fertilization. We identified a group of three closely related pollen tube-expressed MYB transcription factors (MYB97, MYB101, MYB120), which are required for proper interaction of the pollen tube with the female gametophyte. These transcription factors are transcriptionally induced during growth in the pistil. They regulate a transcriptional network leading to proper differentiation and maturation of the pollen tube, promoting proper pollen tube-ovule interactions resulting in sperm release and double fertilization. We used microarrays to discover genes regulated by the transcription factors MYB97, MYB101 and MYB120 in pollen tubes growing through the pistil at 8 hours after pollination. Pistils were collected from ms1 (Male Sterile 1) pistils that were unpollinated, or pollinated with either wild type (Col-0) pollen or myb triple mutant (myb97-1, myb101-4, myb120-3) pollen for 8 hours. We sought to examine transcriptional changes that were taking place in pollen tubes before they reached ovules in wild type pollen tubes, and what portion of this transcriptional regulation was due to MYB97, MYB101 and MYB120. Analysis of growth in the pistil allows discovery of transcriptional changes taking place during pollen tube growth in its native environment, as opposed to mature pollen or in vitro grown pollen, which are essentially naive conditions, as neither have interacted with the pistil environment and any signalling factors found therein.

Project description:Keeping imbibed seeds at low temperatures for a certain period, so called seed vernalization (SV) treatment, promotes seed germination and subsequent flowering in various plants. Vernalization-promoting flowering requires GSH. However, the expression patterns analyzed by GeneChip arrays showed that increased GSH biosynthesis partially mimics SV treatment in Arabidopsis thaliana. SV treatment (keeping imbibed seeds at 4°C for 24 h) induced a specific pattern of gene expression and promoted subsequent flowering in wild-type plants. A similar pattern was observed at 22°C in transgenic plants (35S-GSH1 plants) overexpressing the γ-glutamylcysteine synthetase gene GSH1, coding an enzyme limiting GSH biosynthesis, under the control of the cauliflower mosaic virus 35S promoter. This pattern was strengthened at 4°C but flowering was less responsive to SV treatment. There was a difference in the transcript behaviour of the flowering repressor FLC between wild-type and 35S-GSH1 plants. Unlike other genes responsive to SV treatment, SV-dependent decrease in FLC in wild-type plants was reversed in 35S-GSH1 plants. SV treatment increased GSSG level in wild-type seeds, whereas GSSG level was high in 35S-GSH1 plants, even at a non-vernalizing temperature. Taking into consideration that low temperatures stimulate GSH biosynthesis and bring about oxidative stress, GSSG is considered to trigger low temperature response, but enhanced GSH synthesis was not enough for mimicking SV treatment. To complete it, it essentially required the cellular redox retransition from the oxidized to the reduced state that is observed after the seed vernalization treatment. Four samples (Col-0 and 35S-GSH1 seeds imbibed at 22˚C or 4˚C). Two replicates for each samples.

Project description:Histone variants can effect nucleosome stability or affect histone of DNA modifications. H3.3 is a major H3 histone variant that is incorporated into chromatin outside of S-phase in various eukaryotes. In animals, H3.3 is associated with active transcription and possibly maintenance of transcriptional memory. Plant H3.3, which evolved independently of animal H3.3, is much less well understood. We performed ChIP-chip using chromatin from rosette leaves of 35S:H3.3-YFP plants.

Project description:We investigated RNA involved in the maternal control of progeny seed dormancy. Basically, we grew Ler wild type plants at 22 and 16 degree Celsius before fertilization which were moved to 22 degree for seed maturation along with ft-1 plants at 22 degree through lifetime (which show decreased seed germinability). Various RNA fractions were prepared from developing siluqes (seeds removed) and seeds, and sequenced to identify genes involved in transducing maternal memory of temperature to progeny seeds.

Project description:During seed maturation, the embryo accumulates nutrition storage compounds such as oil and reserve proteins, and acquires dormancy and desiccation tolerance. Arabidopsis transcription factors LEC1, LEC2, FUS3 and ABI3 are known as the master regulators of seed maturation because all these events during the seed maturation are severely affected by the respective mutants. In addition, the lec1, lec2 and fus3 mutants exhibit some heterochronic characteristics, as exemplified by the development of true leaf-like cotyledons during embryogenesis. To characterize these mutants at the whole genome expression level, microarray experiments were performed. Developing seeds were dissected from the siliques of the abi3-6 homozygous plants or the respective wild type plants (Col-0) at 12 and 16 days after flowering. Seeds samples were obtained from triplicate batches of plants and used for RNA preparation.

Project description:Upon germination, pollen forms a tube that elongates dramatically through female tissues in order to reach and fertilize ovules. While essential for the life cycle of higher plants, the genetic basis underlying most of the process is not well understood. We used Affymetrix Arabidopsis ATH1 Genome Arrays covering more than 80% of the Arabidopsis genome to compare transcriptomes of cell-sorted, hydrated pollen grains with those of flowers, leaves, seedlings and siliques (all samples with duplicates). This comparison revealed that pollen expresses a reduced set of genes with increased proportions of enriched and selectively-expressed transcripts. Relative gene ontology (GO) category representations in pollen and vegetative tissues revealed a functional skew of the pollen transcriptome towards signaling, vesicle transport and cytoskeleton, suggestive of a commitment towards germination and tube growth. Relative gene ontology (GO) category representations in pollen and vegetative tissues reveal a functional skew of the pollen transcriptome towards signaling, vesicle transport and cytoskeleton, suggestive of a commitment towards germination and tube growth. Relative gene ontology (GO) category representations in pollen and vegetative tissues reveal a functional skew of the pollen transcriptome towards signaling, vesicle transport and cytoskeleton, suggestive of a commitment towards germination and tube growth. Gene family and pathway analysis allowed formulation of novel hypotheses for the role of non-classical MADS-box genes, small RNA pathways and cell cycle components in pollen.

Project description:The combination of robust physiological models with “omics” studies holds promise for the discovery of genes and pathways linked to how organisms deal with drying. Here we used a transcriptomics approach in combination with an in vivo physiological model of re-establishment of desiccation tolerance (DT) in Arabidopsis thaliana seeds. We show that the incubation of desiccation-sensitive (DS) germinated Arabidopsis seeds in a polyethylene glycol (PEG) solution re-induces the mechanisms necessary for expression of DT. Based on a SNP-tile array gene expression profile, our data indicates that the re-establishment of DT, in this system, is related to a programmed reversion from a metabolic active to a quiescent state similar to prior to germination. Our findings show that transcripts of germinated seeds after the PEG treatment are dominated by those encoding LEA, seed storage and dormancy-related proteins. On the other hand, a massive repression of genes belonging to many other classes such as photosynthesis, cell wall modification and energy metabolism occurs in parallel. Furthermore, comparison with a similar system for Medicago truncatula reveals a significant overlap between the two transcriptomes. Such overlap may highlight core mechanisms and key regulators of the trait DT. Taking into account the availability of the many genetic and molecular resources for Arabidopsis, the described system may prove useful for unraveling DT in higher plants.
