Genome-wide identification of CCD gene family in Peach (Prunus persica L. Batsch) and expression analysis with aroma norisoprenoids.

ABSTRACT:

Background

Carotenoid cleavage dioxygenases (CCDs) are critical enzymes involved in carotenoid degradation. These enzymes play a significant role in determining fruit color and aroma by modifying carotenoid precursors and generating volatile compounds such as norisoprenoids, volatile carotenoid cleavage products. In peach (Prunus persica), there have been many studies showing that PpCCDs are associated with changes in fruit flesh color, but their role in volatile formation remains to be elucidated. This study aims to explore the function of PpCCD genes in carotenoid metabolism and volatile biosynthesis in peach.

Results

There were 10 PpCCD genes identified in peach genome. According to the phylogenetic tree, PpCCD proteins were classified into six groups, CCD1, CCD4, CCD7, C
