Regulation of gene expression governing proline metabolism in Thellungiella salsuginea by NaCl and paraquat

Regulation of gene expression governing proline metabolism in Thellungiella salsuginea by NaCl... Differential expression of the proline metabolism genes in Thellungiella salsuginea (Pall) E. Schulz was investigated under salinity (100 and 300 mM NaCl), upon the effect of paraquat (0.1 μM), and at their joint action. It was shown that, depending on the intensity of stress factor, expression of the P5CS1 gene was induced in the leaves (at 100 mM NaCl) or roots (at 300 mM NaCl). When the plants on control medium were treated with paraquat, the proline content changed only in the leaves. Time course of proline content in the leaves complied with the dynamic of P5CS1 gene expression, while expression of PDH gene essentially did not change. When the plants, which experienced salt stress, were treated with paraquat, the content of proline and the P5CS1 mRNA level increased even more. The obtained results suggest a complicated nature of signaling between the organs of the halophyte Th. salsuginea causing expression of the proline biosynthesis genes in the leaves and roots under the effect of salinity, paraquat, or upon their joint action. The proline catabolism in these plants was maintained essentially unchanged, which is probably related to the participation of proline and/or the products of its degradation in the pathways of other metabolite biosynthesis. We suggested that proline took part in ROS scavenging process and proline level was under strong control in Th. salsuginea. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
