Integration of transcriptomic and metabolomic analysis reveals light-regulated anthocyanin accumulation in the peel of 'Yinhongli' plum.

ABSTRACT:

Background

The 'Yinhongli' cultivar of Chinese plum (Prunus salicina Lindl.) is characterized by a distinctive bicolored peel phenotype, in which anthocyanins serve as crucial determinants of both its visual characteristics and nutritional quality. However, the molecular mechanism of underlying light-dependent anthocyanin biosynthesis of plum, especially its regulatory network and pathway, need to be further studied and explored.

Results

Comprehensive physiological analyses demonstrated distinct pigmentation patterns, revealing that dark-treated (YD) plum peels retained green coloration, whereas light-exposed (YL) and bag-removed samples (YDL) exhibited red pigmentation. Utilizing an integrated approach combining metabolomic and transcriptomic analyses, we identified 266 dif
