摘要
本文综述了寡聚糖类诱抗剂诱导处理后,果蔬组织内部在结构、生化以及分子水平上产生的抗性变化。结构抗性的改变包括细胞膜受体蛋白的发现,细胞膜通透性的改变,胞内结构和细胞壁成分的变化等;生化抗性涉及苯丙烷代谢途径的激活、病程相关蛋白和蛋白酶抑制剂的诱导表达等;分子水平上的抗性变化则涉及组织细胞内抗性相关基因的激活和积累表达。
This review was focused on the changes of structural, biochemical and molecular levels of internal organization in fruit and vegetable after the resistance induced by the treatment with oligosaccharides. The changes of structural resistance mainly include receptor protein presence on cell membrane and change of membrane permeability, intracellular structures and cell wall compositions, the changes of biochemical resistance mainly include activation of phenylpropanoid pathway and expression of PRP and inhibitor protease, and the changes of molecular resistance mainly involve the activation or accumulated expression of the genes related to resistance.
