Expression and transcriptional regulation of amino acid transporters in plants

Abstract:
Recent studies have shown that there are more than 50 amino acid transporter genes in the Arabidopsis genome. This abundance of amino acid transporters implies that they play a multitude of fundamental roles in plant growth and development. Current research on the expression and regulation (i.e., tissue-specific expression and regulation of expression in response to nutrient and environmental changes) of these genes has provided useful information about the functional significance of plant amino acid transport systems.
