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.

盐和干旱是影响农作物植物健康，生长和发育的两种主要非生物胁迫。我们旨在了解植物中的盐和水运输以及土壤盐度的生理影响。使用生物物理模型，我们将量化盐通过植物器官，组织和细胞从根到叶的运动。我们的目的是回答一个问题，即盐如何在不同的组织和主要器官中移动，盐如何在根，叶和芽细胞中积聚，以及如何通过在植物中运行的运输机制的多样性来控制运动和积累。我们旨在量化组织耐受性，渗透耐受性和离子耐受性，并发现植物可以避免盐胁迫作用的新机制。
