Fig. 5From: Overdominant expression of related genes of ion homeostasis improves K+ content advantage in hybrid tobacco leavesThe expression and expression pattern of potassium channel and transport-related genes in H and L hybrids and their parents. Normalized expression values are color-coded according to log2 (FPKM + 1). Significantly (P ≤ 0.05) up-regulated and down-regulated genes are indicated by the red box and black box, respectively, and up/down-regulated overdominant expression patterns are indicated by the upper triangle and lower triangleBack to article page
