Integrated metabolomic and transcriptomic analysis of the anthocyanin regulatory networks in Lagerstroemia indica petals.

ABSTRACT:

Background

Lagerstroemia indica is an ornamental plant with high economic and ecological values. However, the mechanism underlying the regulation of L. indica petal color variation remains unclear. We used LC-MS/MS and RNA-seq to uncover the genetic basis of flower colour variation with the help of the metabolome and transcriptome of three varieties with different colored petal, 'Huahai', 'Zhuimeng', 'Zixian'.

Results

A total of 54 anthocyanidins were identified, 11 peonidin derivatives, 10 cyanidin derivatives, 9 delphinidin derivatives, 5 petunidin derivatives, 5 malvidin derivatives, 4 pelargonidin derivatives, 2 procyanidin derivatives, and 8 other flavonoids. Delphinidin-3-O-glucoside, Malvidin-3-O-glucoside, Petunidin-3-O-glucoside were abundant in petals of all three
