摘      要：Plants typically exhibit the purple phenomenon as a result of an increase in flavonoids and anthocyanins.A new tea germplasm P113 was recently selected from Camellia tachangensis,which is purple in tender *** the present study,integrated transcriptome and metabolome were used to analyze the flavonoid metabolite components and the genes involved in flavonoid biosynthesis in P113 .A total of 86 flavonoid metabolites were identified,including 70 significantly differential metabolites(p0.05)and they were enriched to the three metabolic pathways of ko00941,ko00942 and ko00944 through KEGG pathway analysis.A total of 136 flavonoid involved genes were obtained from transcriptomic study,of which 53 were significantly differentially expressed in developmental *** correlation between metabolite profiling and transcriptome,transcriptome and protein interactions suggested that transcription factor MYB12 and glycosyltransferase UGT78D2 had a good facilitation on purple tender *** metabolic pathways and potential genes that underlie the coloration of the shoots in P113 are clarified in this *** also lays the groundwork for identifying potential genes involved in color variation and offers a theoretical framework for the creation and use of distinctive genetic resources and the breeding of new cultivars.
