Transcriptome profiling of the defense response following elicitation by a bacterial pathogen or flg22

ABSTRACT: Phytoalexins are abundant in edible crucifers and have important biological activities, yet no dedicated gene for their biosynthesis is known. Here, we report two new cytochromes P450 from the non-model plant Brassica rapa (Chinese cabbage) that catalyze unprecedented S-heterocyclizations in cyclobrassinin and spirobrassinin biosynthesis. Our results reveal the first genetic and biochemical insights into the biosynthesis of a prominent pair of dietary metabolites, and have important implications for pathway discovery across >20 recently sequenced non-model crucifers.

RNA-seq of Brassica rapa leaves elicited with either Pseudomonas syringae pv. maculicola or flg22

Project description:Phytoalexins are abundant in edible crucifers and have important biological activities, yet no dedicated gene for their biosynthesis is known. Here, we report two new cytochromes P450 from the non-model plant Brassica rapa (Chinese cabbage) that catalyze unprecedented S-heterocyclizations in cyclobrassinin and spirobrassinin biosynthesis. Our results reveal the first genetic and biochemical insights into the biosynthesis of a prominent pair of dietary metabolites, and have important implications for pathway discovery across >20 recently sequenced non-model crucifers. Leaf mRNA profiles of four conditions (Pseudomonas syringae pv. maculicola, flg22, and their respective mock treatments) were tested in triplicate.

Tracing the transcriptomic changes of synthetic trigenomic allohexaploid in Brassica by RNA-Seq approach

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.

iTRAQ-based quantitative proteomic analysis reveals new metabolic pathways responding to cold stress in two Winter Turnip Rape (Brassica rapa L.), part 1

Project description:Winter turnip rape (Brassica rapa L.) is a valuable ecologically beneficial oil crop that is produced mainly for its ability of conserving soil and water in winter and spring and its high quality edible oil in northwestern China. However, coldness and extremely low temperature negatively affects the growth and development of winter turnip rape, resulting in failure to overwinter and production in northwestern China. ‘Longyou 7’(Brassica rapa L.) and ‘Tianyou 4’ (Brassica rapa L.) are closely related plant species, but their cold tolerances are different. ‘Longyou 7’ is a cold-tolerant cultivar, ‘Tianyou 4’is a cold-sensitive cultivar. In this study, we used iTRAQ-based proteomics to compare quantitative changes in the proteome of two winter turnip rape leaves and roots in response to cold stress to elucidate the possible molecular mechanism underlying the ability of ‘Longyou 7’ to adapt to cold stress.

Transcriptome analysis for leaf morphology in Brassica rapa

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

Transcription profiling of Brassica lines

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.

Chloroplast-genome-wide maps of small RNAs in Chinese cabbage (Brassica rapa) and Arabidopsis thaliana (Ler).

Project description:Deep sequencing provided evidence that a novel subset of small RNAs were derived from the chloroplast genome of Chinese cabbage (Brassica rapa) and Arabidopsis (Ler). The chloroplast small RNAs (csRNAs) include those derived from mRNA, rRNA, tRNA and intergenic RNA. The rRNA-derived csRNA were preferentially located at the 3M-CM-"M-BM-^@M-BM-^Y-ends of the rRNAs, while the tRNA-derived csRNAs were mainly located at 5M-CM-"M-BM-^@M-BM-^Y-termini of the tRNAs. After heat treatment, the abundance of csRNAs decreased in chinese cabbage seedlings, except those of 24 nt in length. The novel heat-responsive csRNAs and their locations in the chloroplast were verified by Northern blotting. The regulation of some csRNAs to the putative target genes were identified by real-time PCR. Our results indicated that high temperature regulated the production of some csRNAs, which may have potential roles in transcriptional or post-transcriptional regulation, and affected putative target genes expression in chloroplast. Examination of two replicates of heat treated (HT) and control (MT) Chinese cabbage sample respectively, and one Arabidopsis (Ler) RNA sample.

The chloroplast small RNAs (csRNAs) include those derived from mRNA, rRNA, tRNA and intergenic RNA.

After heat treatment, the abundance of csRNAs decreased in chinese cabbage seedlings, except those of 24 nt in length. The novel heat-responsive csRNAs and their locations in the chloroplast were verified by Northern blotting.
