摘要:
水通道蛋白(AQP)是高度多样化的内在蛋白家族,可运输水和中性溶质,在植物发育和胁迫反应中起着至关重要的作用。然而关于月季(Rosa chinensis)AQP的组成和生物学功能仍知之甚少,以月季品种坦尼克为试验材料,基于全基因组分析,对月季AQP家族成员进行鉴定和生物信息学分析,并分析相关基因在干旱胁迫下的表达情况。结果表明,共鉴定出61个AQP编码基因的非冗余成员,其中57个可定位于9条染色体上。系统发育分析结果表明,月季AQP(RsAQP)分为4个亚家族,包括21个质膜内在蛋白(PIP)、19个液泡膜内在蛋白(TIP)、16个NOD样内在蛋白(NIP)和5个小碱性内在蛋白(SIP),所有RsAQP都包含共同的高度保守基序、跨膜区域及多种顺式作用元件,表明RsAQP具有潜在跨膜转运功能。RNA-Seq表达模式分析结果表明,PIP1表达水平普遍高于其他亚群;qRT-PCR结果进一步表明,7个PIP1亚群成员中,6个基因(RsPIP1-1、RsPIP1-2、RsPIP1-3、RsPIP1-4、RsPIP1-6、RsPIP1-7)在干旱胁迫下上调表达,以RsPIP1-6表达水平最高、契合度最高,推测RsPIP1-6可能是月季耐旱的关键基因。
