Project description:Flowers have a species-specific fertile period during which pollination and fertilization have to occur to initiate seed and fruit development. Within the flower, the functional life span of the ovule containing the female gametophyte is decisive for fertilization and the initiation of seed development. Here we performed an RNA-sequencing based transcriptome analysis of senescing unfertilized ovules during in a time series. We isolated ovules from Arabidopsis thaliana flowers emasculated at stage 12c at three different time points: 2 days after emasculation (DAE), 3 DAE, and 4 DAE. These time points correspond to intact mature ovules (2DAE), early ovule senescence (3 DAE), and late ovule senescence (4 DAE). We extracted total RNA from the ovules in 3 independent biological replicates, thus generating 9 RNA samples in total, for RNA-sequencing by Illumina HiSeq.
Project description:This dataset provides the transcriptome of the central cell of the female gametophyte from Arabidopsis thaliana. We sequenced two biological replicates. Each replicate started with a pool of 450 central cells collected using laser-assisted microdissection (LAM). Libraries were prepared as described in DOI:10.1038/NMETH.1315. Each library was sequenced on one eight of a slide on the AB SOLiD platform (version 3). IMPORTANT: In the alignment files (.bam), we named the mitochondrial and the chloroplastidial chromosomes ChrM and ChrC. This is different from the "chloroplast" and "mitochondrium" names in the whole genome fasta file available on TAIR.
Project description:Transcriptional profiling in young flowers (stage 8) of Arabidopsis wild type control plants and sdg2-1 mutant is performed using Aligent’s Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K). A significant number of genes involved in gametophyte development are found differentially regulated in the sdg2-1 mutant.
Project description:In this project, we profiled the dynamics of proteome during Arabidopsis early embryogenesis using nanoproteomics. In addition, we identified some proteins which may be important during this process. Combining with RNA-seq, we unveiled the relationship between RNA and proteins during Arabidopsis early embryogenesis.
