摘要:
研究白粉菌胁迫对苦荬菜叶片生理指标及蛋白组的影响,为揭示苦荬菜响应白粉菌胁迫的分子机制奠定基础。以龙牧苦荬菜(Lactuca indica L. cv. Longmu)为试验材料,测定其接种白粉菌72 h后叶片生理指标的变化,并利用同位素相对和绝对定量标记技术联合液相色谱-串联质谱技术(iTRAQ-LC-MS/MS)结合生物信息学方法分析叶片差异表达蛋白及其富集情况。结果表明,接种白粉菌后过氧化物酶活性较对照极显著增加(P<0.01),丙二醛含量和超氧化物歧化酶活性均显著增加(P<0.05),总叶绿素、叶绿素a和叶绿素b含量均下降。共筛选出200个差异表达蛋白,其中上调表达的蛋白有161个,下调表达的蛋白有39个。经过蛋白注释和富集分析,筛选出含Bet v 1结构域蛋白、含几丁质结合1型结构域蛋白、过氧化物酶、细胞色素P450、4-香豆酸-辅酶A连接酶-7、咖啡酸3-O-甲基转移酶和大根香叶烯A羟化酶7种差异表达蛋白与苦荬菜响应白粉菌胁迫有关。苦荬菜在白粉菌胁迫下,次生代谢和病程相关等蛋白显著上调表达以响应白粉病侵染,推测过氧化物酶可能在机体响应白粉菌胁迫的调控中发挥了重要作用。
