Anthocyanin metabolites and related regulatory genes analysis in leaves of Acer Pseudosieboldianum mutant during different periods of color change

Among all anthocyanins of A. pseudosieboldianum mutant leaf, Cyanidin-3-O-glucoside remained high in all three stages of leaves, which is main substances for the leaf color. Additionally, 20 structure gene, 12 transcription factors and some genes associated with anthocyanin synthesis and transport were screened and there was a complex metabolic network in mutant leaves. This study provided a basis for resource innovation and landscaping applications of Acer plants by analyzing the anthocyanin metabolites and expression of DEGs in the leaf coloring process.
