Project description:We explored the transcriptomic changes of synthetic Brassica allohexaploid by comparing to its parents using a high-throughput RNA-Seq method. A total of 35644409 sequence reads were generated, and 32642 genes were aligned from the data. There were 29260, 29060 and 29697 genes identified in Brassica rapa, Brassica carinata, and Brassica allohexaploid, respectively. We screened differentially expressed genes (DEGs) by a standard of two-fold or greater change in expression and false discovery rate (FDR) no more than 0.001. As a result, 7397 DEGs were detected between Brassica hexaploid and its parents. A large proportion of the 3184 DEGs between Brassica hexaploid and its paternal parent B. rapa was involved in biosynthesis of secondary metabolites, plant-pathogen interaction, photosynthesis, and circadian rhythm. Between Brassica hexaploid and its maternal parent B. carinata, 2233 DEGs were screened. A lot of them had functions of plant-pathogen interaction, plant hormone signal transduction, ribosome, limonene and pinene degradation, photosynthesis, and also biosynthesis of secondary metabolites. In addition, we found many transcription factor genes, methyltransferase and methylation genes that showed differential expression between Brassica hexaploid and its parents.

Project description:Among Brassica rapa, rapid cycling Brassica rapa and Brassica rapa inbred line Kenshin showed contrasting leaf morphology. To identify genes associated with leaf morphology, four distinct F2 progeny of RcBr X Kenshin cross and their parents were selected. Leaf samples were collected from 6 materials, isolated total RNA, and subjected to newly developved 135K microarray. Experiments were performed with three or two biologic

Project description:Transcription profiling of Brassica rapa, Brassica oleracea and Brassica napus I and II The nuclear genomes of the resynthesised B. napus lines should be identical but, as one (B. napus I) involved a cross of B. oleracea onto B. rapa, and the other (B. napus II) involved a cross of B rapa onto B. oleracea, they differ in cytoplasm, and hence contain different chloroplast and mitochondrial genomes.

Project description:Cytosine DNA methylation (mC) can silence transposable elements (TEs) and regulate gene expression. However, the mechanism and function of DNA methylation reprogramming during plant development are still largely unknown. To explore the DNA methylation dynamics during the male sexual-lineage development in the Brassicaceae family, we assessed the mC level in meiocyte, microspore and pollen of a Brassica rapa doubled haploid (DH) line by whole genome bisulfite sequencing (WGBS). Analysis of global mC profiles showed that significant reprogramming of CHH methylation occurred in the Brassica rapa male sex cells, similar to that observed in Arabidopsis. Analysis of differential methylation sites identified specific methylation loci in sex cells that can target and possibly regulate gene expression, suggesting a mechanism consistent with that of Arabidopsis. Quite a few long terminal repeat (LTR) transposable elements were activated in meiocyte and microspore, which correlated with reduced DNA methylation. Expression analysis of key genes that affect DNA methylation showed that active methylation and demethylation occurred during male sexual lineage development. These results suggest a conserved DNA methylation reprogramming mechanism during Brassica rapa male sex lineage development. The transcriptome and DNA methylome data obtained will also be useful for other mechanism studies in Brassica rapa.

Project description:The mapping and functional analysis of quantitative traits in Brassica rapa can be greatly improved with the availability of physically positioned, gene-based genetic markers and accurate genome annotation. In this study, deep transcriptome RNA sequencing (RNA-Seq) of Brassica rapa was undertaken with two objectives: SNP detection and improved transcriptome annotation. We performed SNP detection on two varieties that are parents of a mapping population to aid in development of a marker system for this population and subsequent development of high-resolution genetic map. An improved Brassica rapa transcriptome was constructed to detect novel transcripts and to improve the current genome annotation. Deep RNA-Seq of two Brassica rapa genotypesâR500 (var. trilocularis, Yellow Sarson) and IMB211 (a rapid cycling variety)âusing eight different tissues (root, internode, leaf, petiole, apical meristem, floral meristem, silique, and seedling) grown across three different environments (growth chamber, greenhouse and field) and under two different treatments (simulated sun and simulated shade) generated 2.3 billion high-quality Illumina reads. In this experiment, two pools were made, with one pool consisting of 66 samples collected from growth chamber and another pool consisting of 60 samples collected from greenhouse and field. Each pool was sequenced on eight lanes (total 16 lanes) of an Illumina Genome Analyzer (GAIIx) as 100-bp paired end reads.
