摘要
植物强大的再生能力使其在复杂的自然环境中得以生存。植物再生是植物对受损结构自我修复或替代的过程。例如,离体的枝条或叶片掉落在湿润的土壤表面后,能够在伤口处快速再生不定根,从而顽强地生存下去。伤口信号是启动植物再生的第一项生物学事件。近年来,有关伤口信号及其在植物再生过程中信号转导的研究取得了重要进展。本文综述了伤口信号参与植物再生的分子机制,并对未来的研究方向进行了展望。
Plants have evolved powerful strategies to survive in severe natural environment.Regeneration is a process in which plants repair or replace damaged tissues or organs.For example,adventitious roots could be formed around the wound site directly from detached branches or leaves under proper conditions.Wounding is the first event triggering regeneration.In recent years,important progresses have been made in the study of the nature of wound and the signal transduction pathway in promoting plant regeneration.In this paper,the type of wound signals in plants and the molecular transaction pathway in promotion of plant regeneration are reviewed,and the future research direction is prospected.
