The Transcriptome of Brassica napus L. Roots under Waterlogging at the Seedling Stage.

ABSTRACT: Although rapeseed (Brassica napus L.) is known to be affected by waterlogging, the genetic basis of waterlogging tolerance by rapeseed is largely unknown. In this study, the transcriptome under 0 h and 12 h of waterlogging was assayed in the roots of ZS9, a tolerant variety, using digital gene expression (DGE). A total of 4432 differentially expressed genes were identified, indicating that the response to waterlogging in rapeseed is complicated. The assignments of the annotated genes based on GO (Gene Ontology) revealed there were more genes induced under waterlogging in "oxidation reduction", "secondary metabolism", "transcription regulation", and "translation regulation"; suggesting these four pathways are enhanced under waterlogging.
