Abstract:

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.

Key words: oligosaccharides, fruit and vegetable, induced disease resistance, defense mechanism
