Fig. 3From: Metabolomic and transcriptomic insights into how cotton fiber transitions to secondary wall synthesis, represses lignification, and prolongs elongationFour clusters of Gb and Gh fiber metabolites included three that were similar between genotypes. Metabolites with changes in concentration during fiber development (p ≤ 0.05) were clustered. The x-axis is as defined for Fig. 2. The y-axis is the scaled imputed mean value of metabolite concentration standardized to mean = 0 and standard deviation = 1. Color coding is as described in Fig. 2 Back to article page
