General soybean transcriptional response to water deficit. Color coding is consistent throughout the figure and defined in the pie chart. (A), The distribution of E-type (E-only and E-ambiguous) genes are indicated as the proportion of the circle; n = 12,827. (B), The maximum difference relative to 0 hr control of each gene is plotted with regard to its expression profile type. For each profile type, the mean, variance, and skewness of a distribution is estimated. Boxes indicate the middle quartile range of this distribution; lines indicate the highest and lowest quartile range. Dots indicate expression levels that extend beyond the estimated distribution. (C), Expression profile models are illustrated, with functional enrichment categories labeling each profile.
