Exploring the mechanisms underlying petal pigmentation differences in two cultivars of a Physalis philadelphica L. based on HPLC and NGS.

At present, there are few reports on the study of the flower color of Physalis philadelphica L. In order to clarify the metabolic characteristics of flower color of Physalis philadelphica L. and obtain key gene information of flower color metabolism, this study took the trait of flower color of Physalis philadelphica L. as the starting point, and analyzed related pigment components and relative content by HPLC. Choose 2 kinds of hair iron the Physalis philadelphica L.var. Tieba(yellow flower), the veins stood out Physalis philadelphica L. var. Qingjin (yellow purple flower), 2 times (coated) early flowering, NGS analysis of 12 samples, The metabolic pathways related to flower color metabolism of Physalis philadelphica L. were studied. In order to clarify the characteristics of color formation and obtain the DEGs of color formation.
