Abstract:

Oxidative stress induced by ROS (reactive oxygen species) as a key factor in bio-control system has gained
tremendous attention. ROS, on the one hand, it is necessary for sustaining life activity; on the other hand, it is harmful to
cellular protein and DNA so that it should be scavenged. How to utilize ROS effectively during the process of bio-control to
enhance controlling efficiency is highly desired. This paper summarizes the mechanisms of ROS generation and scavenging,
expounds the interactions of oxidative stress with ROS, antagonist and host vegetables and fruits, and discusses the positive
and negative impact of ROS on postharvest disease resistance in vegetables and fruits as well as the influence of relevant
actions on the bio-control efficiency.

Key words: oxidative stress, ROS, antagonist, fruits and vegetables, postharvest disease, bio-control
