摘要
花生(Arachis hypogaea)是世界范围内经济且营养丰富的食物来源,然而受干旱、盐碱、食草昆虫和病毒等多种非生物和生物胁迫影响,致使花生产量降低。DMP基因家族成员编码一种植物特异性膜蛋白(未知功能域679膜蛋白),已被指出在植物的生殖发育和衰老等各种生理过程中发挥作用。本研究中,共鉴定和分析了花生中12个DMP基因。系统发育分析表明,这些DMP可分为3个亚科。此外,进行了保守基序、基因结构、系统发育关系、染色体分布、共线性分析和蛋白互作分析。盐胁迫和干旱胁迫下的表达模式分析显示,AhDMP4、AhDMP8和AhDMP10可能是花生耐盐和耐旱的候选基因。这项全基因组研究提供了对花生DMP基因家族的系统分析,并为了解候选基因的潜在功能提供了进一步的洞见。
Peanut(Arachis hypogaea)is a worldwide economic and nutritious food source.However,peanut yield is reduced due to various abiotic and biotic stresses,such as drought,salinity,herbivorous insects,and viruses.The DMP gene family members encode a plant-specific membrane protein(unknown function domain 679 membrane protein),which has been identified to play a role in various physiological processes in plants,such as reproductive development and senescence.In this study,a total of twelve DMP genes in peanut were identified and analyzed.Phylogenetic analysis showed that these DMPs can be divided into three subfamilies.In addition,the conserved motifs,gene structure,phylogenetic relationships,chromosomal distribution,collinearity analysis,and protein interactions were conducted.The expression patterns under salt and drought stresses revealed that AhDMP4,AhDMP8,and AhDMP10 might be the candidate genes for salt and drought tolerance.This genome-wide study provides a systematic analysis of the peanut DMP gene family and offers further insight into the potential functions of the candidate genes.
