Genome-wide characterization of the β-1,3-glucanase gene family in Gossypium by comparative analysis.

ABSTRACT: The β-1,3-glucanase gene family is involved in a wide range of plant developmental processes as well as pathogen defense mechanisms. Comprehensive analyses of β-1,3-glucanase genes (GLUs) have not been reported in cotton. Here, we identified 67, 68, 130 and 158 GLUs in four sequenced cotton species, G. raimondii (D5), G. arboreum (A2), G. hirsutum acc. TM-1 (AD1), and G. barbadense acc. 3-79 (AD2), respectively. Cotton GLUs can be classified into the eight subfamilies (A-H), and their protein domain architecture and intron/exon structure are relatively conserved within each subfamily. Sixty-seven GLUs in G. raimondii were anchored onto 13 chromosomes, with 27 genes involved in segmental duplications, and 13 in tandem duplications. Expression patterns showed highly developmental and spatial
