Fig. 4From: The structure, functional evolution, and evolutionary trajectories of the H+-PPase gene family in plantsExpression differentiation in H+-PPase gene family members. Genes of different subfamilies within one species are arranged in descending order according to expression level in young roots. Black squares indicate type non-Ia; black triangles indicate type II; and unlabeled indicate type Ia. * indicates no biological repeat in GSE70369Back to article page
