Project description:Analysis of the different gene expression profiles of natural and resynthesized Brassica polyploids with Illumina deep sequencing technology could help to improve our knowledge of polyploid genome evolution. We obtained approximately 6 million sequence tags per sample,and 6018254, 5930726, 6022170, 5950123, 5991210, 5798939, 5823113, 5772449,5858527 and 5657697 clean tags were obtained in libraries of B. rapa, B. oleracea, B. napus-F1, B. napus-F2, B. napus-F3, B. napus-F4, natural B. napus, B. nigra, B. juncea and B. carinata, respectively.16574, 15970, 22059, 18155, 16479, 18196, 17448, 13867, 19424 and 16645 genes of B. rapa genome were unambigously mapped by sequence tags of these ten DGE libraries, respectively. Differentially expressed genes during polyploidization were broadly discovered by comparing the tetraploids with their progenitors.

Differentially expressed genes during polyploidization were broadly discovered by comparing the tetraploids with their progenitors. mRNA obtained from young leaves of 28-days-old seedlings were compared during polyploidization.

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.

Four-condition experiment, comparison of transcription profiles of the genomes. Four biological replicates were used, independently grown and harvested. One replicate per array.

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:Successful pollination brings together the mature pollen grain and stigma papilla to initiate an intricate series of molecular processes meant to eventually enable sperm cell delivery for fertilization and reproduction. At maturity, the pollen and stigma cells have acquired proteomes comprising the primary molecular effectors required upon their meeting. In Brassica species, knowledge of the roles and global composition of these proteomes is largely lacking. To address this gap, gel-free shotgun proteomics was performed on the mature pollen and stigma of Brassica carinata, a representative of the Brassica family and its many crop species (e.g. B. napus, B. oleracea, B. rapa), which holds considerable potential as a bio-industrial crop. 5608 and 7703 B. carinata mature pollen and stigma proteins were identified, respectively. The pollen and stigma proteomes were found to reflect not only their many common functional and developmental objectives, but also important differences underlying their cellular specialization. Isobaric tag for relative and absolute quantification (iTRAQ) was exploited in the first analysis of a developing Brassicaceae stigma, and uncovered 251 B. carinata proteins that were differentially abundant during stigma maturation, providing insight into proteins involved in the initial phases of pollination.

Project description:we deep-sequenced two small RNA libraries made from V. longisporum infected/non-infected roots and employed Brassica rapa and Brassica oleracea genomes as reference for miRNA prediction and characterization as well. We identified 893 B. napus miRNAs representing 360 conserved and 533 novel miRNAs, and mapped 429 and 464 miRNAs to AA and CC genomes, respectively. Among them, 62 miRNAs were responsive to the V. longisporum infection.
