Genome-Wide Analysis of <i>AAT</i> Genes and Their Expression Profiling during Fiber Development in Cotton

Amino acid transporters (<i>AATs</i>) are a kind of membrane proteins that mediate the transport of amino acids across cell membranes in higher plants. The AAT proteins are involved in regulating plant cell growth and various developmental processes. However, the biological function of t...
