Heatmap of differential expression in KEGG pathways between sexual and vegetative tissue. Pixels represent Log2(sexual – vegetative) read counts for a pathway. Significantly different pairwise expressions were identified by Fisher’s exact tests after Benjamini-Hochberg adjustment (P < 0.05) between sexual and vegetative tissue collected at the Spring reproductive cycle, i.e. F vs Veg, and M vs Veg. Blue indicate under-expression and yellow over-expression of sexual relative to vegetative tissue. Asterisks indicate significant pairwise comparisons within a pathway: in white- sex under-regulated pathway compared to the vegetative tissue; in black – male- or female up-regulated pathway relative to the vegetative tissue.
