In this project the student will test whether wheat and rice plants with high capacities for silicon uptake can produce 'more crop per drop' of water. Silicon is an abundant element long thought of as being unreactive and non-essential for plants. However, some plants accumulate very high levels of silicon and the benefits of this for their protection against threats such as drought and pathogen attack have now become clear. For example, we have recently discovered that silicon accumulates in the guard cells of stomata on plant leaves and helps them to act quickly. These cells are particularly important as they adjust the stomatal pores to control how much carbon dioxide enters the plant for photosynthesis, and how much water is lost. Plants that can react more quickly to a changing environment should be able to use water more efficiently and could have advantages under rising CO2levels and future warmer, drier climate scenarios. The student will learn to use molecular and physiological techniques and use these to explore the potential role for silicon in future food security

在这个项目中，学生将测试具有高硅素吸收能力的小麦和水稻植株是否能在每滴水中产生更多的作物。硅是一种丰富的元素，长期以来被认为是无活性的，对植物来说不是必需的。然而，一些植物积累了非常高水平的硅，这对它们抵御干旱和病原体攻击等威胁的好处现在已经变得显而易见。例如，我们最近发现，硅积累在植物叶片上气孔的保卫细胞中，并帮助它们迅速采取行动。这些细胞尤其重要，因为它们调节气孔，以控制有多少二氧化碳进入植物进行光合作用，以及有多少水分损失。能够对不断变化的环境做出更快反应的植物应该能够更有效地利用水分，并在二氧化碳水平上升和未来更温暖、更干燥的气候情景下具有优势。学生将学习使用分子和生理技术，并利用这些技术来探索硅在未来食品安全中的潜在作用。
