Comparative Transcriptome Analysis Points to the Biological Processes of Hybrid Incompatibility between Brassica napus and B. oleracea.

ABSTRACT: Improving Brassica napus via introgression of the genome components from its parental species, B. oleracea and B. rapa, is an important breeding strategy. Interspecific hybridization between B. napus and B. rapa is compatible with high rate of survival ovules, while the hybridization between B. napus and B. oleracea is incompatible with the high occurrence of embryo abortion. To understand the diverse embryo fate in the two interspecific hybridizations, here, the siliques of B. napus pollinated with B. oleracea (AE) and B. rapa (NE) were employed for transcriptome sequencing at 8 and 16 days after pollination. Compared to NE and the parental line of B. napus, more specific differentially expressed genes (DEGs) (12
