Correlation of the temporal and spatial expression patterns of HQT with the biosynthesis and accumulation of chlorogenic acid in Lonicera japonica flowers.

ABSTRACT: Hydroxycinnamoyl-CoA quinate transferase (HQT) is one of the key enzymes in the biosynthesis of chlorogenic acid (CGA) in the flowers of Lonicera japonica. However, the spatiotemporal expression patterns of HQT and its relationship to the dynamics of CGA biosynthesis, transport, and storage remain largely unknown. In this study, we collected L. japonica flower samples at different growth stages (S1-S6) and examined the spatiotemporal expression pattern of HQT and the dynamic accumulation patterns of CGA using a combination of molecular and cytological techniques. Our results suggest that the spatiotemporal expression pattern of HQT is directly correlated with dynamic changes in CGA accumulation and distribution in L. japonica flowers. We further sh
