Abstract

Cotton is one of the most economically important crops worldwide. Seed size is a vital trait for plants connected with yield and germination. encodes a RING_Ubox E3 ubiquitin ligase that controls seed development by affecting cell growth. Here, are few reports on -like genes in cotton, and the function of in cotton is poorly understood. In the present study, a genome-wide analysis identified 6 and 3 like genes in each of the two cultivated tetraploids ( and ) and each of their diploid ancestral species (, ), respectively. has the same functional domain and high sequence similarity with in . Overexpression of in significantly reduced seed and seedling size, suggesting is a potential target for regulating cotton seed size. These results provided information on the genetic and molecular basis of -like genes in cotton, thus establishing a foundation for functional studies of cotton seeds.

摘要

棉花是全球经济上最重要的作物之一。种子大小是与产量和发芽相关的植物重要性状。[基因名称]编码一种RING_Ubox E3泛素连接酶，其通过影响细胞生长来控制种子发育。目前，关于棉花中类似[基因名称]基因的报道较少，且对其在棉花中的功能了解甚少。在本研究中，全基因组分析分别在两种栽培四倍体（陆地棉和海岛棉）及其二倍体祖先物种（亚洲棉和雷蒙德氏棉）中各鉴定出6个和3个类似[基因名称]的基因。[基因名称]与[另一物种中的基因名称]具有相同的功能结构域和高度的序列相似性。在[棉花品种]中过表达[基因名称]显著减小了种子和幼苗的大小，表明[基因名称]是调控棉花种子大小的一个潜在靶点。这些结果提供了棉花中类似[基因名称]基因的遗传和分子基础信息，从而为棉花种子的功能研究奠定了基础。
