Differences in Anthocyanin Accumulation Patterns and Related Gene Expression in Two Varieties of Red Pear.

ABSTRACT: Red pear is a popular fruit that is appreciated for its attractive and distinctive appearance and mild flavor. In this study, we investigated the mechanism underlying the red coloration of pear skin using the 'Xinqihong' cultivar-which was selected as a spontaneous bud sport mutant of the 'Xinli 7'(Pyrus betulifolia Rehd.) variety and has a stronger red color that is retained in the mature fruit-as an experimental model. We compared the phenotype and gene expression patterns of the two varieties and found no significant differences at the early stage of fruit development. However, although the red color of 'Xinli 7' fruits began to fade 107 days after full bloom, that of 'Xinqihong' fruits persisted until the time of harvest. Transcriptome sequencing identified 639 genes that were d
