Comprehensive genomic characterization of cotton cationic amino acid transporter genes reveals that GhCAT10D regulates salt tolerance.

ABSTRACT:

Background

The cationic amino acid transporters (CAT) play indispensable roles in maintaining metabolic functions, such as synthesis of proteins and nitric oxide (NO), biosynthesis of polyamine, and flow of amino acids, by mediating the bidirectional transport of cationic amino acids in plant cells.

Results

In this study, we performed a genome-wide and comprehensive study of 79 CAT genes in four species of cotton. Localization of genes revealed that CAT genes reside on the plasma membrane. Seventy-nine CAT genes were grouped into 7 subfamilies by phylogenetic analysis. Structure analysis of genes showed that CAT genes from the same subgroup have similar genetic structure and exon number. RNA-seq and real-time PCR indicated that the expression of most GhCAT genes were induced
