From: A genome-wide analysis of the small auxin-up RNA (SAUR) gene family in cotton
Distribution of SAUR genes on Gossypium raimondii (a), G. arboreum (b), G. hirsutum (c), and G. barbadense (d) chromosomes. The scale represents megabases (Mb). The chromosome numbers of G. raimondii (D5_chr1 - D5_chr13), G. arboreum (A2_chr1 - A2_chr13), G. hirsutum (AD1_A01 - AD1_A13, AD1_D01 - AD1_D13), and G. barbadense (AD2_A01 - AD2_A13, AD2_D01 - AD2_D13) are indicated above each vertical bar
