Transcript isoforms and alternative splicing in polyploid Brassica napus under heat and cold stress.

ABSTRACT:

Background and aims

Polyploidization events have occurred many times during the evolution of flowering plants and have played a major role in genome evolution. Genes duplicated by polyploidy, termed homeologues, can diverge in function or new functions can evolve. There has been considerable interest in characterizing the transcriptomes of polyploid plants. One aspect of gene expression is alternative splicing (AS) by which precursor mRNAs are differentially spliced to form multiple mature mRNA isoforms. The effects of abiotic stress conditions on transcript isoform diversity of homeologues in polyploids has received little attention. Brassica napus, an allopolyploid derived from B. rapa and B. oleracea, is a model to study genetic complexities in polyploids. Brassica napus contain
