The 2002-03 drought cost Australia in the order of $10Billion and 70,000 jobs. Associated with reduced rainfall is increased sunlight irradiance, which exacerbates the reduction in crop yield due to the combined damage of a water deficit and oxidative damage caused by the excess light. Plants have networks of responses to minimise damage due to drought and excess light. We have identified a novel class of genes that optimise or alter different aspects of these networks and we wish to define the nature of that optimisation to determine how it could be transfered to crop plants.

2002-03年的干旱使澳大利亚损失了100亿美元和7万个工作岗位。与降雨量减少相关的是阳光辐照度增加，这加剧了作物产量的减少，这是由于水分不足和过量光照引起的氧化损伤的综合损害。植物有网络的反应，以尽量减少由于干旱和过度光照造成的损害。我们已经发现了一类新的基因，它们可以优化或改变这些网络的不同方面，我们希望定义这种优化的性质，以确定如何将其转移到作物中。
