SUV（the Suppressor of variegation [Su（var）] homologs and related）基因家族是SET基因家族的一个亚组。根据SRA结构域和WIYLD结构域的分布，可将其分为两类，即SUVH（the Suppressor of variegation [Su（var）] homologs）和SUVR（the Suppressor of variegation [Su（var）] related）。本研究在异源多倍体甘蓝型油菜及其二倍体祖先中鉴定了139个SUV基因，并对其进化关系、蛋白质性质、基因结构、模体分布、转座元件、顺式作用元件和基因表达模式进行了分析。结果表明，B. napus在异源多倍体化过程中扩增，其中片段重复和TRD起着关键作用。将芸苔属和拟南芥属分离后，对同源基因的分析表明，在B的进化过程中，许多SUV基因丢失。rapa，B. oleracea和B.油菜。对30对可能存在进化关系的直向同源基因对的基因、蛋白质结构和表达模式进行分析，结果表明，绝大多数直向同源基因在基因结构和蛋白质基序上是保守的，但只有4对基因具有相同的表达模式。
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 separation of Brassica and Arabidopsis lineages, orthologous gene analysis showed that many SUV genes were lost during the evolutionary process in B. rapa, B. oleracea and B. napus. The analysis of the gene and protein structures and expression patterns of 30 orthologous gene pairs which may have evolutionary relationships showed that most of them were conserved in gene structures and protein motifs, but only four gene pairs had the same expression patterns.
