Improving salt tolerance by optimising ion transport in chloroplasts

点击翻译按钮获取中文摘要

This project aims to discover the ion transport mechanisms and their molecular origins in chloroplasts that differentiate halophytes from glycophytes, allowing halophytes to optimise photosynthesis during salt stress. Yield losses in crop plants are linked to the effects of salt stress on their chloroplasts, but some plants maintain growth and yield irrespective of high soil salinity. This project will use biophysics to characterise mutants deficient in targeted chloroplast transporters, comparing a model glycophyte and closely related halophyte. The expected outcome of these fundamental molecular is salt-tolerant crop plants.
