Fig. 4From: Systematic characterization of Gossypium GLN family genes reveals a potential function of GhGLN1.1a regulates nitrogen use efficiency in cottonCollinearity relationship between the homologous GLN genes of the four cotton species. The lines in different colors connect collinear gene pairs. The chromosome numbers are shown in boxes and are denoted as GhA1–A13, GhD1‒D13, GbA1–A13, GbD1‒D13, GaChr01- Chr13 and GraiChr01- Chr13Back to article page
