Epigenetic modifications occurred at DNA sequence and chromatin,including DNA methylation,histone modifications,chromatin remodeling,and non-coding RNAs,are essential to transcriptional regulation. This study introduces the recent progress on mechanisms of DNA methylation and DNA demethylation,and summarizes the roles and function of DNA methylation,histone modification,histone variants,RNA methylation and non-coding RNAs in the development and ripening of horticultural fruits. In addition,this review highlights the potential and unsolved issues related to investigating fleshy fruits of horticultural crops,and provides the theoretical foundation for the investigation,innovation,and utilization of fruit biology research in the future.

Key words: horticultural crop, fruit, development, DNA methylation, DNA demethylation, histone modification, non-coding RNA, fruit biology
