Transcriptomic and metabolomic analyses reveal how girdling promotes leaf color expression in Acer rubrum L

Abstract

Highlights 1. Comparisons between leaves on girdled and non-girdled branches of red maple showed that leaf color change is a coevolutionary phenomenon of maple in response to abiotic stress. 2. C108619.graph_c0 of Pkinase family regulates the color change of A. rubrum leaf by participating in the synthesis of anthocyanins, which has the high homology with c45897.graph_c0 and OsEDR1 of Lagerstroemia indica.
