全球70%与农业相关的用水都是通过植物叶片的气孔。保护细胞对植物的光合碳同化和水分利用效率有着深远的影响。我们最近演示了如何使用OnGuard建模软件对保护细胞进行定量数学建模，从而产生足够的细节来指导表型和突变分析。这一进展代表了指导保护细胞功能的“逆向工程”应用的重要一步，以提高水利用效率和碳同化。然而，对于那些不熟悉建模者的思维方式的人来说，OnGuard是具有挑战性的。在实践中，每个模型结构代表一个有待检验的假设，通过模型预测和实验结果之间的比较来丢弃、验证或改进。这里列出的几个指导方针总结了OnGuard软件用户的标准和逻辑起点。
Much of the 70% of global water usage associated with agriculture passes through stomatal pores of plant leaves. The guard cells, which regulate these pores, thus have a profound influence on photosynthetic carbon assimilation and water use efficiency of plants. We recently demonstrated how quantitative mathematical modeling of guard cells with the OnGuard modeling software yields detail sufficient to guide phenotypic and mutational analysis. This advance represents an all-important step toward applications in directing "reverse-engineering" of guard cell function for improved water use efficiency and carbon assimilation. OnGuard is nonetheless challenging for those unfamiliar with a modeler's way of thinking. In practice, each model construct represents a hypothesis under test, to be discarded, validated or refined by comparisons between model predictions and experimental results. The few guidelines set out here summarize the standard and logical starting points for users of the OnGuard software.
