Fig. 3

Module-trait correlations and gene expression patterns of the top 2 modules correlated with alginate and mannitol contents. a Module-trait relationships and corresponding p values. The color scale on the right shows correlations from − 1 (green) to 1 (red). Panels on the left represent alginate and mannitol content as traits. Other panels show the expression variations of each biosynthetic gene as a trait. b Expression patterns of each selected module. “Brown4” and “Darkgreen” were highly correlated with alginate content, whereas “Black” and “Darkslateblue” were highly correlated with mannitol content
