Abstract
Based on previous researches, we further investigated the multi-silique trait in rapeseed (Brassica napus L.) line zws-ms. In this study, we used a relatively comprehensive list of flowering related genes in rapeseed and compared them between zws-ms and its near-isogenic line (NIL) zws-217. Genes were studied on genome, transcriptome and proteome levels and then we focused on genes with non-synonymous single nucleotide polymorphism (SNP) or frame-shift insertion-deletion (InDel), finding some genes on the list which changes their sequences. Then, combined with their annotation and the information of their orthologs, certain genes such as BnaA09g05900D, ortholog of AGAMOUS-LIKE 42 (AGL42), which encodes an MADS-box protein, were assumed as probably responsible for the multi-silique trait. Also, we analyzed the Differentially Accumulated Proteins (DAPs) between zws-ms and zws-217, revealing some genes involved in homologous recombination and mismatch repair pathways. Since the development of flowers/siliques is crucial to crops and it influences the yield of rapeseed, this study paved a way to deeply understand the mechanism of the multi-pistil flower formation, which may facilitate researches on rapeseed production in future.
