活性氧调控果实发育成熟的研究进展

活性氧(reactive oxygen species,ROS)存在于整个植物生长发育过程,一旦积累过多会导致氧化应激反应,但是适度的氧化胁迫有利于果实成熟。本文对活性氧影响果实成熟的生理机制,活性氧与激素互作调控果实成熟的机理,活性氧调控果实成熟的分子机制,以及活性氧与钙离子调控采后果实后熟等相关研究进展进行了总结和评述,旨在通过总结活性氧直接或间接调控果实衰老成熟的研究进展,为今后利用活性氧调控果实成熟提供理论依据和参考。

Advances in ROS promoting fruit development and ripening

ROS is produced along the fruit development, which often damages proteins, lipids, carbohydrates, and DNA, causing severe cell membrane damage and inducing programmed cell death. But moderate oxidative stress is conducive to fruit ripening. The physiological mechanism of ROS affecting the fruit ripening, the interaction mechanism of ROS and hormones regulating fruit ripening, the molecular mechanism of ROS directly regulating the fruit ripening, the cooperative interaction of ROS and calcium ions regulating postharvest fruit ripening were summarized, to provide a theoretical basis and reference for employing ROS to regulate fruit ripening directly or indirectly.
