植物光破坏防御机制研究进展

摘要

The photoprotective mechanism is a protective measure to deal with the complex and changeable natural environment. These measures from morphological, physiological and biochemical aspects reflect the ability of plants to adapt to the environment. According to the mechanism of inhibition of light, light damage to present situation and the plant defense mechanisms and xanthophyll cycle in higher plants mechanism studies were reviewed in recent years. It was believed that the defense mechanism of the xanthophyll cycle plant photoprotection is one of the important measures for plant photoprotection.%光破坏防御机制是植物为应对复杂多变的自然环境而产生的保护措施，这些措施从形态、生理和生化等方面反映了植物对环境的适应能力。本文根据光抑制的机理，对近年来植物的光破坏防御机制以及高等植物叶黄素循环机制的研究现状进行综述，认为叶黄素循环防御机制是植物光保护作用的重要措施之一。
