The phosphatidy ethanolamine-binding proteins (PEBP) play an important role in controlling flower development and phase change. Here, a total of 61 PEBP genes were identified, in which 20, 21, 10, and 10 were from tetraploid Gossypium hirsutum (AD1) and G. barbadense (AD2), and diploid G. raimondii (D5) and G. arboreum (A2), respectively. In G. hirsutum, 20 identified PEBP genes were unevenly distributed on 12 chromosomes. The identified PEBP genes were classified into four groups (TFL1, MFT, FT and FT-like). Among those, FT-like group are unique to cotton. The majority of PEBP genes had similar intron/exon distribution, whereas the divergence of PEBP genes suggests the possibility of functional diversification. The expression of PEBP genes varied among different tissues. This study brings new insights into the integrated genome-wide identification of PEBP genes in cotton and provides a foundation for breeding cotton cultivars with early maturation.
磷酯乙醇胺结合蛋白（PEBP）在控制花发育和阶段转变中起着重要作用。在这里，共鉴定出 61 个 PEBP 基因，其中 20、21、10 和 10 个分别来自四倍体陆地棉（AD1）和海岛棉（AD2）以及二倍体亚洲棉（D5）和雷蒙德氏棉（A2）。在陆地棉中，鉴定出的 20 个 PEBP 基因不均匀分布在 12 条染色体上。鉴定出的 PEBP 基因被分为四个组（TFL1、MFT、FT 和 FT-like）。其中，FT-like 组是棉花特有的。大多数 PEBP 基因具有相似的内含子/外显子分布，而 PEBP 基因的分化表明其功能多样化的可能性。PEBP 基因的表达在不同组织中存在差异。本研究为棉花中 PEBP 基因的全基因组综合鉴定提供了新的见解，并为培育早熟棉花品种提供了基础。
