摘要:
为探讨番茄斑萎病(TSWV)侵染后,不同抗性番茄与防御酶活性的关系,揭示番茄抵御TSWV侵染的生理生化机制。选取4份前期在田间筛选获得的对TSWV有不同抗性的番茄种质材料(抗病种质材料2T826、2T1062及感病种质材料2T482、2T1130),接种TSWV后,观察不同抗性番茄种质材料的症状表现,并利用ELISA方法研究相关防御酶活性的变化。结果表明,接种TSWV后,2份感病种质材料表现出明显的番茄斑萎病症状,而2份抗病种质材料则无明显症状。对于感病种质材料,接种TSWV后,2T482中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)、苯丙氨酸解氨酶(PAL)活性均低于对照,多酚氧化酶(PPO)活性和丙二醛(MDA)含量高于对照;2T1130中SOD、CAT活性及MDA含量均低于对照,PAL、PPO活性高于对照。对于抗病种质材料,接种TSWV后,2T826中SOD、CAT活性均低于对照,POD、PAL、PPO活性及MDA含量均高于对照;2T1062中SOD、CAT、PPO活性均低于对照,POD、PAL活性及MDA含量均高于对照。受TSWV侵染后,不同抗性番茄种质材料通过诱导POD、PAL、PPO活性,对TSWV产生氧化应激反应,与植株抗性关联性大。本研究结果为揭示番茄抗TSWV的生理生化机制提供了理论依据,并为抗TSWV番茄育种提供参考。
