Our work is directed toward understanding the basis of plant tolerance to environmental stresses including drought, salt and low temperature stress. We are investigating the fundamental genetic and molecular responses to environmental stress in order to understand the basis of tolerance to stress and develop strategies to improve tolerance to drought and salt toxicity. Unpredictable changes in climatic conditions, including drought and extreme temperatures pose challenging and costly risks to agriculture. Plants have a wide genetic variation for stress tolerance and throughout the history of agriculture there has been genetic selection for improved yield under stress conditions. The need to improve tolerance in plants is increased by changing climatic conditions and the success in achieving improvements will be dependent on understanding the biological mechanisms underpinning stress tolerance. My laboratory has identified a large number of regulatory genes in wheat whose change in expression correlates with the level of tolerance of wheat different genotypes.

我们的工作旨在了解植物对干旱、盐和低温等环境胁迫的耐受性基础。我们正在研究对环境胁迫的基本遗传和分子反应，以了解对胁迫的耐受性的基础，并制定策略来提高对干旱和盐毒性的耐受性。气候条件的不可预测变化，包括干旱和极端气温，给农业带来了具有挑战性和代价高昂的风险。植物对胁迫耐受性具有广泛的遗传变异，并且在整个农业历史中，存在用于在胁迫条件下提高产量的遗传选择。气候条件的变化增加了提高植物耐受性的需求，而实现改善的成功将取决于对支撑胁迫耐受性的生物学机制的理解。本实验室已经鉴定了大量小麦中的调控基因，它们的表达变化与小麦不同基因型的耐性水平相关。
