Comprehensive Analysis of the SUV Gene Family in Allopolyploid Brassica napus and Its Diploid Ancestors.

ABSTRACT: SUV (the Suppressor of variegation [Su(var)] homologs and related) gene family is a subgroup of the SET gene family. According to the SRA domain and WIYLD domain distributions, it can be divided into two categories, namely SUVH (the Suppressor of variegation [Su(var)] homologs) and SUVR (the Suppressor of variegation [Su(var)] related). In this study, 139 SUV genes were identified in allopolyploid Brassica napus and its diploid ancestors, and their evolutionary relationships, protein properties, gene structures, motif distributions, transposable elements, cis-acting elements and gene expression patterns were analyzed. Our results showed that the SUV gene family of B. napus was amplified during allopolyploidization, in which the segmental duplication and TRD played critical roles. After the
