摘要
【目的】果实大小是衡量果实产量和品质的关键指标,解析果树果实大小的遗传调控具有重要意义。【方法】通过查阅文献,系统总结了近年来果树果实大小的调控机制研究进展。【结果】果实大小由果实内细胞数目和细胞体积共同决定,依赖于细胞分裂和细胞扩张的协同调控。果实发育是一个复杂而精密调控的过程,涉及多种调控因素,包括细胞周期、植物激素(IAA、GA、CK、BR、ABA等)、转录因子(CYP78、AP2/ERF、bHLH、MADS-box、MYB、NAC、WRKY等)、microRNA、Hippo、泛素化-蛋白酶体途径和表观遗传修饰等。【结论】概述控制果树果实大小的遗传位点及分子调控因素,探讨了多种途径共同调控果实大小的作用机制,对植物激素互作及调控机制、激素与转录因子以及转录因子之间互作调控果树果实大小提出了展望。
【Objective】Fruit size is an important agronomic trait,closely associated with yield and quality.This study aims to provide a reference for further research on the regulatory mechanism related to fruit size in fruit crops.【Method】By reviewing the literature,we systematically summarized recent research advances concerning the molecular regulation of fruit size regulation in fruit crops.【Result】Fruit size is determined by both cell number and cell volume,which are regulated by cell division and cell expansion.Fruit development is a complex and highly regulated process involving various factors,including the cell cycle,plant hormones(IAA,GA,CK,BR,ABA,etc.),transcription factors(CYP78,AP2/ERF,bHLH,MADS-box,MYB,NAC,WRKY,etc.),microRNAs,Hippo signaling pathway,ubiquitinationproteasome pathway,and epigenetic modifications.【Conclusion】This paper outlines the genetic loci and molecular regulatory factors controlling fruit size in fruit crops,investigates the mechanisms by which multiple pathways jointly regulate fruit size.It also provides prospects in the crosstalk between plant hormones,hormones and transcription factors,as well as the interactions between transcription factors in controlling fruit size in fruit crops.
