Abstract：Fruit development and ripening is a complicated process．Fruit weight，shape，
color，quality and flavor will change along with the fruit development and ripening，and be regulated
by a series of fruit developmental genes．Studying the molecular mechanism of fruit development
is of great importance for improving fruit quality in the future．Therefore，this paper focuses on 2
species：Arabidopsis and tomato，and summarizes the gene excavation and gene interaction involved
in fruit development and ripening．Besides，it also overviews the research progress on the molecular
mechanisms for regulating fruit development，and provides certain theoretical guidance for future studies
on fruit development and plant breeding.
