摘要
柑橘是种植最为广泛且价值颇高的水果作物之一。果皮色泽不仅与柑橘成熟度密切相关,还直接影响消费者购买意愿,影响其商品价值。柑橘果皮着色过程受到柑橘本身的遗传背景、发育阶段和组织结构等内在因素,及贮藏温度和光照等环境因素的影响。此外,内源植物激素的变化和外源植物激素处理均对柑橘果实着色有重要影响。植物激素中乙烯、脱落酸、茉莉酸和生长素在促进柑橘果皮转色过程中发挥重要作用,而赤霉素通常被视为果皮转色的负调节因子。植物激素通过影响激素代谢和信号转导,改变内源激素比例,重建内源激素平衡,进而通过调控叶绿素和类胡萝卜素代谢途径相关基因的表达,影响柑橘果皮的色泽。此外,多种转录因子被证明参与柑橘色素调节、激素代谢和信号转导,而植物激素能通过影响转录因子调节作用影响柑橘果皮着色。该综述查阅国内外相关研究,总结了近年来植物激素调控柑橘果皮色泽的研究概况,以期为后续研究提供参考。
Citrus is one of the most extensively cultivated and economically significant fruit crops.The color of citrus peel serves as an indicator of ripeness,influencing both consumer preferences and commercial value.The coloration of citrus peel is determined by internal factors such as citrus genetic background,developmental stage,and tissue structure,along with environmental factors like storage temperature and light.In addition,changes in endogenous phytohormones and exogenous phytohormone treatment play a critical role in the coloration of citrus fruits.Notably,phytohormones like ethylene,abscisic acid,jasmonic acid,and auxin are crucial in enhancing citrus peel coloration,while gibberellin typically acts as a suppressor.The coloration of citrus peel is influenced by the regulation of genes related to phytohormone metabolism and signal transduction by theses phytohormones.This process restores the balance of endogenous phytohormones,thereby regulating genes involved in the pathways of chlorophyll and carotenoid metabolism.Transcription factors are essential for regulating not only chlorophyll and carotenoid metabolism but also phytohormone metabolism and signal transduction.Furthermore,phytohormones influence coloration by regulating the functions of these transcription factors.This review consulted relevant domestic and international research,summarized recent advancements in the understanding of the regulation of citrus peel color by phytohormones,and offers a reference for future studies.
