Water is the single most limiting factor in agriculture and the world's supply of fresh water is diminishing, the greatest fraction of total water use being by agriculture. Progress in water-use efficiency will have social value, and this program should help us to achieve it. Our progress in this area is already one of the most successful of 'bottom-up' approaches - in the sense of transferring knowledge from biochemistry and biophysics to breeding and agronomy, as CSIRO now has a successful wheat breeding program based on this earlier work of ours. Now that we have discovered a gene that controls water-use efficiency at the leaf level, we wish to see how the gene works, and how it affects mineral nutrition of leaves.

水是农业中唯一的最大限制因素，世界淡水供应正在减少，农业用水占总用水量的最大部分。水资源利用效率的进步将具有社会价值，该计划将帮助我们实现这一目标。我们在这一领域的进展已经是“自下而上”方法中最成功的一种--从生物化学和生物物理学知识转移到育种和农艺学的意义上说，CSIRO现在有一个基于我们早期工作的成功小麦育种计划。现在我们已经发现了一个在叶片水平上控制水分利用效率的基因，我们希望了解该基因是如何工作的，以及它如何影响叶片的矿物质营养。
