Fig. 8From: Integrated analysis of the transcriptome and metabolome reveals the molecular mechanism regulating cotton boll abscission under low light intensityDifferent expressions of structural genes and metabolites in flavonoid biosynthesis pathway. Red block represent up-regulation and green, blue represent downregulation of expression, respectively. Enzyme annotation: PAL (Phenylalanine ammonia lyase), C4H (Cinnamate4-hydroxylase), 4CL (4—coumarate:CoA ligase), CHS (Chalcone synthase), CHI (Chalcone isomerase), F3’H (Flavonoid 3-hydroxylase), FLS (Flavonol synthase), DFR (Dihydroflavonol 4-reductase)Back to article page
