Fig. 9From: Comparative transcriptome and metabolome analyses provide new insights into the molecular mechanisms underlying taproot thickening in Panax notoginsengExpression patterns of DEGs assigned to cell wall metabolism in the four taproot transcriptomes, March, May, July, and November. The log-transformed expression values range from − 1 to 1. Red and blue colors indicate up- and down- regulated transcripts, respectivelyBack to article page
