摘　　要：柑橘果实粒化是成熟期以及贮藏期容易发生的一种生理性病害。木质素的积累与柑橘粒化的形成密切相关,汁胞木质化作为柑橘果实粒化过程中最明显的现象之一,备受果树研究者们的关注,并取得了一定的研究进展。本文以木质素的生物合成及其调控方式作为研究柑橘果实汁胞粒化的切入点,对木质素生物合成途径中的关键酶基因以及相关转录因子的研究进展进行综述,并对木质素合成途径调控柑橘果实粒化形成机制中存在的问题进行总结以及今后的研究方向进行展望,以期为柑橘果实粒化的后续研究提供借鉴。The granulation of citrus fruits is a physiological disease that is easy to occur in fruit ripening and postharvest storage.The accumulation of lignin is closely related to the formation of granulation of citrus fruits.The lignification of juice sacs is one of the most obvious phenomena in the process of granulation of citrus fruits.It has attracted the attention of fruit tree research scholars and achieved certain research progress.Therefore,this paper will use lignin biosynthesis and its regulation as the entry point to study the granulation of citrus fruits,review the research progress of key enzyme genes and related transcription factors in lignin biosynthesis pathway,and the problems in the mechanism of lignin synthesis in the regulation of citrus fruit granulation were summarized and the future research directions were prospected in order to provide reference for the follow-up research on citrus fruit granulation.
