摘　　要：着色是果实的重要品质性状,也是果树育种计划的重要目标之一。随着更多高质量的果树基因组测序完成,与花青素相关的果实着色的分子调控机制已取得了重要进展,特别是转座子作为重要调控元件控制MYB转录因子影响果实着色的机制,在一些重要果树上已被揭示。综述了转座子调控果树果实着色的相关进展,特别是基于基因组给出了控制梨果实着色的2个重要转录因子MYB10和MYB114启动子区的转座子插入注释,希望能为红色梨以及其他园艺植物果实着色的分子生物学研究提供有价值的线索和思路。Fruit coloration is a target quality trait for fruit breeders in various fruits breeding programs.In general,the pigment in fruits is derived from anthocyanin.With the completion of genome sequence of most fruits,the important advances have been acquired in the molecular mechanism of fruit coloring.In particular,the mechanism of transposons acting as important regulatory element in control of fruit coloration has been revealed in some important fruit trees.This review describes the progresses on transposon-mediated MYB gene regulation of the anthocyanin biosynthesis in several important fruits,What’s more,based on the available genome of Pyrus communis Bartlett DH,the promoters of MYB10 and MYB114 controlling pear fruit coloration was discovered with an LTR retrotransposon insertion,respectively,which will provide a valuable clue and idea for studying the molecular mechanism of fruit coloration in red pear and other horticultural plants.
