Comprehensive profiling of alternative splicing landscape during secondary dormancy in oilseed rape (Brassica napus L.).

ABSTRACT: Alternative splicing is a general mechanism that regulates gene expression at the post-transcriptional level, which increases the transcriptomic diversity. Oilseed rape (Brassica napus L.), one of the main oil crops worldwide, is prone to secondary dormancy. However, how alternative splicing landscape of oilseed rape seed changes in response to secondary dormancy is unknown. Here, we analyzed twelve RNA-seq libraries from varieties "Huaiyou-SSD-V1" and "Huaiyou-WSD-H2" which exhibited high (> 95%) and low (< 5%) secondary dormancy potential, respectively, and demonstrated that alternative splicing changes led to a significant increase with the diversity of the transcripts in response to secondary dormancy induction via polyethylene glycol 6000 (PEG6000) treatment. Among the four bas
