Phosphatidylethanolamine-binding-protein (PEBP) domain-containing proteins play important roles in multiple developmental processes of plants; however, functions of few members in the gene family have been elucidated in rice and other crops. In this study, we found that twenty genes identified in rice are not evenly distributed on the chromosomes. Four colinear pairs are identified, suggesting the duplication of during evolution. The OsPEBPs are classified into six subgroups by phylogenetic analysis. The structure of all the genes and encoded proteins are similar. The 262 PEBP domain-containing proteins from crops are divided into six groups. The number of colinear pairs varies between rice and other crops. More than thirty -acting elements in the promoter region of are discovered. Expression profiles of genes are differential. Most of the expression can be regulated by NaCl, ABA, JA, and light, indicating that may be involved in the control of the response to the environmental signals. These results lay sound foundation to further explore their functions in development of rice and crops.
含磷脂酰乙醇胺结合蛋白（PEBP）结构域的蛋白质在植物的多个发育过程中发挥重要作用；然而，该基因家族在水稻和其他作物中的少数成员的功能尚未阐明。在本研究中，我们发现水稻中鉴定出的20个基因在染色体上分布不均。鉴定出四对共线对，表明在进化过程中发生了重复。通过系统发育分析，将水稻PEBP蛋白分为六个亚组。所有基因和编码蛋白的结构相似。来自作物的262个含PEBP结构域的蛋白分为六组。水稻和其他作物之间共线对的数量有所不同。在启动子区域发现了30多个作用元件。基因的表达谱存在差异。大多数基因的表达可受NaCl、ABA、JA和光的调节，表明其可能参与对环境信号响应的调控。这些结果为进一步探索它们在水稻和作物发育中的功能奠定了良好基础。
