Central to the supremacy of seed plants was the evolution of active, metabolic control of the stomata; the pores that regulate both plant productivity and water loss. However, little is known about the transition from passive control of stomata in seedless plants to active stomatal control in seed plants. This project will identify the key physiological and genetic innovations that underpinned the evolution of stomatal control over the past 410 million years. Understanding these evolutionary innovations will offer important insights into stomatal function in seed plants, as well as informing models of global productivity and water use through time, with benefits for Australian agriculture and natural resource management.

种子植物至高无上的核心是气孔的进化，气孔是调节植物生产力和水分流失的气孔。然而，对于无核植物气孔的被动控制向种子植物气孔的主动控制的转变知之甚少。该项目将确定在过去4.1亿年中支撑气孔控制进化的关键生理和遗传创新。了解这些进化创新将为种子植物的气孔功能提供重要的见解，并为全球生产力和水资源利用模型提供信息，对澳大利亚农业和自然资源管理有利。
