Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the modes of control exercised by compatible solutes over the activity of major plasma membrane transporters involved in plant adaptive responses to salinity. The work will substantially advance our understanding of salt tolerance and will provide a sound basis for genetic engineering of salt tolerant crops.

植物对盐条件的反应是细胞质中相容溶质的水平显著升高。这些溶质似乎并不直接参与常规的细胞保护，而是在细胞代谢中起调节作用。该项目将应用一系列最先进的生物物理和分子技术来研究相容性溶质对参与植物对盐度适应性反应的主要质膜转运蛋白活性的控制模式。这项工作将大大提高我们对耐盐性的认识，并将为耐盐作物的基因工程提供良好的基础。
