Genome-wide identification of the AAT gene family in quinoa and analysis of its expression pattern under abiotic stresses.

ABSTRACT:

Background

Plant amino acid transporters play an important role in the absorption of soil amino acids by roots, the transport of amino acids between xylem and phloem, plant growth and development, and response to abiotic stress.

Result

In this study, we identified 147 AAT genes in the quinoa genome sequence and categorized them into 12 subfamilies on the basis of their similarity and phylogenetic relationships with AAT found in Arabidopsis thaliana. Interestingly, these AAT genes are not evenly distributed on the quinoa chromosomes. Instead, most of these genes are centrally located on the outer edges of the chromosome arms. After performing motif analysis and gene structure analysis, we observed the consistent presence of similar motifs and intron-exon distribution patterns
