Transcriptomic and metabolomic analysis provides insights into anthocyanin and procyanidin accumulation in pear.

ABSTRACT:

Background

Pear is one of the most important fruit crops worldwide. Anthocyanins and procyanidins (PAs) are important secondary metabolites that affect the appearance and nutritive quality of pear. However, few studies have focused on the molecular mechanism underlying anthocyanin and PA accumulation in pear.

Results

We conducted metabolome and transcriptome analyses to identify candidate genes involved in anthocyanin and PA accumulation in young fruits of the pear cultivar 'Clapp Favorite' (CF) and its red mutation cultivar 'Red Clapp Favorite' (RCF). Gene-metabolite correlation analyses revealed a 'core set' of 20 genes that were strongly correlated with 10 anthocyanin and seven PA metabolites. Of these, PcGSTF12 was confirmed to be involved in anthocyanin and PA accumulat
