Salt and drought are the two major abiotic stresses affecting crop plant health, growth and development. We aim to understand salt and water transport in plants and the physiological effects of soil salinity. Using biophysical models, we will quantify the movement of salt through plant organs, tissues and cells, from root to leaf. We aim to answer the question of how salt moves across the different tissues and major organs, how salt accumulates in root, leaf and shoot cells, and how movement and accumulation is controlled by the diversity of transport mechanisms operating in plants. We aim to quantify tissue tolerance, osmotic tolerance and ionic tolerance and discover new mechanisms by which plants can stave off the effect of salt stress.

盐和干旱是影响作物健康和生长发育的两大非生物胁迫。我们的目的是了解盐和水在植物中的运输和土壤盐度的生理效应。利用生物物理模型，我们将量化盐通过植物器官、组织和细胞，从根到叶的运动。我们的目标是回答盐如何在不同组织和主要器官之间移动的问题，盐如何在根、叶和芽细胞中积累，以及盐的运动和积累如何受到植物中多种运输机制的控制。我们的目标是量化组织耐受性、渗透耐受性和离子耐受性，并发现植物抵御盐胁迫的新机制。
