摘要
脂氧合酶(LOXs)是植物脂质代谢途径中的关键酶类,在植物生长发育、果实成熟和响应外界环境等生命过程中发挥重要作用。随着对其功能研究的逐步深入,LOXs在园艺作物品质形成和调控中的关键作用日益受到关注。本文综述了LOXs的结构类型、生物学功能及其在植物代谢途径中的作用机制,重点探讨了LOXs对园艺作物外观、风味和营养品质形成的多方面影响。进一步总结了基于调节LOXs以改善园艺产品品质、延长货架期的采前管理和采后处理方法,最后对LOXs领域的未来研究方向进行了展望,以期为园艺作物品质调控提供新的理论视角与实践指导。
Lipoxygenases(LOXs)are pivotal enzymes in the plant lipid metabolic pathway,exerting a crucial role in plant growth and development,fruit ripening,and response to external environment along the whole life cycle.The essential role of LOXs in quality formation and regulation of horticultural crops has been elucidated with further exploration on the function of LOXs.This paper comprehensively reviewed the structural types,biological functions,and underlying mechanism of LOXs in plant metabolic pathways.The multi-faceted impacts of LOXs on formation of quality traits such as appearance,flavor,and nutritional quality in horticultural crops were highlighted.Furthermore,it also discussed the effective pre-harvest managements and post-harvest treatments used to improve the quality of horticultural products and extend their shelf-life based on the regulation of LOXs.Finally,prospective research directions of LOXs were suggested,aimed to provide new theoretical perspectives and practical guidance for quality regulation of horticultural crops.
