Fig. 3From: Accumulation mechanism of metabolite markers identified by machine learning between Qingyuan and Xiushui counties in Polygonatum cyrtonema HuaMining of key candidate genes in flavonoid biosynthesis. A Volcano plot of flavonoids metabolites; B Relative content of flavonoids compounds. C Volcano map of differentially expressed genes (p-value < 0.05). D Correlation of flavonoids and modules. E qRT-PCR of PcOMT10/11/12/13 in N. benthaniana leaves. F Changes in chrysoeriol-6,8-di-C-glucoside content after overexpression in N. benthaniana leaves. G Flavonoid biosynthesis pathway and expression of key genes in the P. cyrtonema. Green genes show that compound accumulation is inhibited, whereas red genes promote compound accumulationBack to article page
