Fig. 4From: Genome-wide characterization of the WAK gene family and expression analysis under plant hormone treatment in cottonThe synteny relationships of WAK genes among three sequenced cotton species. G. hirsutum, G. raimondii and G. arboreum chromosomes are indicated in red, orange and pink, respectively. The putative orthologous WAKs between G. arboreum and G. hirsutum, and between G. raimondii and G. hirsutum are connected by blue and orange lines, respectively. Black lines connect the putative paralogous gene pairs (GhWAK15/GhWAK16, GhWAK2/GhWAK9, GhWAK8/GhWAK20, GhWAK5/GhWAK22, GaWAK7/GaWAK6, GaWAK3/GaWAK12 and GrWAK7/GrWAK11)Back to article page
