Metabolome analysis reveals flavonoid changes during the leaf color transition in Populus × euramericana 'Zhonghuahongye'.

ABSTRACT:

Introduction

To investigate the mechanism of leaf color change at different stages in Populus × euramericana 'Zhonghuahongye' ('Zhonghong' poplar).

Methods

Leaf color phenotypes were determined and a metabolomic analysis was performed on leaves at three stages (R1, R2 and R3).

Results

The a*, C* and chromatic light values of the leaves decreased by 108.91%, 52.08% and 113.34%, while the brightness L values and chromatic b* values gradually increased by 36.01% and 13.94%, respectively. In the differential metabolite assay, 81 differentially expressed metabolites were detected in the R1 vs. R3 comparison, 45 were detected in the R1 vs. R2 comparison, and 75 were detected in the R2 vs. R3 comparison. Ten metabolites showed significant differen
