Project description:In this study, we aim to present a global view of transcriptome dynamics during seed development in a large-seeded chickpea (genotype JGK3). We generated about 1.5 billion high-quality reads from 24 libraries (leaf and seven seed developmental stages in three biological replicates) using Illumina high-throughput sequencing platform. We mapped the reads to the kabuli chickpea genome for estimation of their transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses between different samples/stages.

Project description:Seed desiccation during maturation is important process for seed post-maturation behavior and harvest. However, the desiccation mechanism in soybean seed maturation is hardly known. In this study, water content in seed, pod and pedicel decreased faster than that in peduncle and stem. Therefore, we focus on the pedicel during seed maturation. By morphological analysis, the deposits in xylem vessels were confirmed in pedicel at 61 day after flowering (DAF), when there are not the deposits in peduncle. It was clarified by microarray analysis that lignin biosynthesis related genes expressed in pedicel at 61 DAF. Indeed, GmPAL, Gm4CL, GmC3H and GmCAD, which are lignin biosynthesis related genes, increased in pedicel during seed maturation. Furthermore, lignin content in pedicel also increased toward at 61 DAF and accumulated in the xylem vessels. These results suggested that lignin deposits into xylem vessels in pedicel cause the soybean seed desiccation during seed maturation.

Project description:Time course of gene expression profiles during seed development and maturation in Brassica napus were studied using Combimatrix Brassica microarray. The time course expression of 90K Brassica napus EST contigs were measured at 8 developing seed stages of 10, 15, 20, 25, 30, 35, 40 and 45 DAF (days after flowering) using single color microarray

Project description:Ten-eleven translocation (Tet) hydroxylases (Tet1-3) oxidize 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). In neurons increased 5hmC levels within gene bodies correlate positively with gene expression. Here, we studied 5hmC profiles (hMeDIP) during retinal maturation between postnatal week 2 and postnatal week 3 using HiSeq 2000 instrument. Study of retinal 5hmC profile dynamics in 2-week old and 3-week old wild type (WT) mouse.

Project description:How epigenetics is involved in the transition from seed maturation to seed germination largely remains elusive. To uncover the possible role of epigenetics in gene expression during the transition from seed maturation to seed germination in soybean, the transcriptome of cotyledons from four stages of soybean seed maturation and germination, including mid-late maturation, late maturation, seed dormancy and seed germination, were profiled by Illumina sequencing. For the genes that are quantitatively regulated at the four stages, two antagonistic epigenetic marks, H3K4me3 and H3K27me3, together with the binding of RNA polymerase II, were investigated at the four stages by chromatin immunoprecipitation (ChIP). For 10 out of 16 genes examined, the relative enrichment of histone modification marks (H3K4me3 and H3K27me3) and RNA polymerase II binding on their promoter regions correlates well with their relative expression levels at four stages, suggesting the involvement of epigenetics in transcriptional regulation. A striking finding is that seed germination-specific genes start to show open chromatin (H3K4me3) during late seed maturation although their transcripts do not accumulate, which is further supported by RNA polymerase II binding. Together, our results provide the first evidence that seed germination genes can be primed for transcription (open chromatin and RNA polymerase II binding) during seed maturation, highlighting that the transition from seed maturation to seed germination starts at late seed maturation stages at both the genetic and epigenetic levels. Illumina sequencing of transcripts from cotyledons of mid-maturation (B1 stage) and late maturation (AA1 stage) seeds, whole dry seeds, and cotyledons of seedlings six days after imbibition.
