ABSTRACT For years, ethylene has been known to humankind as the plant hormone responsible for fruit ripening. However, the multitasking aspect of ethylene is still being investigated as ever. It is one of the most diversified signaling molecules which acclimatize plant under adverse conditions. It promotes adventitious root formation, stem and petiole elongation, opening and closing of stomatal aperture, reduces salinity and metal stress, etc. Presence of ethylene checks the production and scavenging of reactive oxygen species by strengthening the antioxidant machinery. Meanwhile, it interacts with other signaling molecules and initiates a cascade of adaptive responses. In the present mini review, the biosynthesis and sources of ethylene production, interaction with other signaling molecules, and its exogenous application under different abiotic stresses have been discussed.

植物非生物胁迫下乙烯信号的简要评价

摘要 多年来，乙烯是人类已知的负责果实成熟的植物激素。然而，乙烯的多任务处理方面仍在研究中。它是在不利条件下使植物适应环境的最多样化的信号分子之一。它促进不定根形成、茎和叶柄伸长、气孔开合、降低盐度和金属胁迫等。乙烯的存在通过加强抗氧化机制来抑制活性氧的产生和清除。同时，它与其他信号分子相互作用并启动一系列适应性反应。在目前的小型评论中，乙烯生产的生物合成和来源，与其他信号分子的相互作用，
