Integrated transcriptomics and metabolomics analysis of flower petals color transition in different phenotype of <i>Lonicera macranthoides</i>.

ABSTRACT:

Background

Lonicera macranthoides is a classic Chinese medicinal herb with direct flower color variation among types. Our group found differences in petal color transition between Xianglei-type (XL) and Wild-type (WT). At f1-f4 stage, the two types were green, and gradually changed from green to greenish white with development, in f5-f6, WT from white to golden yellow, but XL has little color change.

Methods

Combined with transcriptomics and metabolomics analysis, the color conversion differences between XL and WT petals of Lonicera macranthoides were analyzed.

Results

Significant differential genes were identified at f1-f4, f5 and f6 in WT and XL, 14528, 7955 and 17985, respectively. At f1, the WT anthocyanin gene showed lower than XL (P < 0.05),
