Recent Progress in Research of Proline Transport Genes

doi:10.11983/CBB17192

Abstract

Abstract: As a wide-spread stress adaption in plants, proline accumulation is thought to result from increased biosynthesis and decreased degradation. However, accumulating reports showed that proline transport also plays a role in stress-induced proline accumulation. In plants, several amino acid transporter protein families, such as AAPs, LHTs and ProTs, can transport proline. In this review, we summarize the expression pattern, function and expression regulation of these families in terms of proline transport, with an aim to provide some useful information on proline transport and accumulation research in plants.

Key words: proline, proline transport, amino acid transporter protein, expression regulation
