Genomic identification of cotton SAC genes branded ovule and stress-related key genes in Gossypium hirsutum.

ABSTRACT: SAC genes have been identified to play a variety of biological functions and responses to various stresses. Previously, SAC genes have been recognized in animals and Arabidopsis. For the very first time, we identified 157 SAC genes in eight cotton species including three diploids and five tetraploids with 23 SAC members in G. hirsutum. Evolutionary analysis classified all cotton SAC gene family members into five distinct groups. Cotton SAC genes showed conserved sequence logos and WGD or segmental duplication. Multiple synteny and collinearity analyses revealed gene family expansion and purifying selection pressure during evolution. G. hirsutum SAC genes showed uneven chromosomal distribution, multiple exons/introns, conserved
