Physiological ecology of nutrients acquisition in terrestrial plants

PI的实验室研究陆生植物获取营养的生理生态学。它研究了营养离子通量在细胞，整个生物体和生态系统水平上的作用，在几个领域：谷物的产量潜力，森林演替，细胞离子相互作用，干旱和盐胁迫。关键的兴趣是植物获取氮，植物钾稳态，离子获取和盐胁迫下的稳态机制，以及在质膜上的主要通量机制的能量成本。实验方法的范围从数学建模和高精度测量营养通量使用放射性示踪剂，营养代谢和收购，植物组织的离子和代谢分析，表达分析的运输，电生理学，呼吸分析和实地测量和试验的遗传操作。PI的实验室以其对完整植物生理学的研究，开发新方法来解决与整个系统相关的复杂性，以及努力确定从植物离子运输生理学的机制研究中出现的实用建议而闻名。

The PI's laboratory studies the physiological ecology of nutrient acquisition in terrestrial plants. It examines the role of nutrient ion fluxes at cellular, whole-organism, and ecosystem levels, in several areas: yield potential in cereals, forest succession, cellular ionic interactions, and drought and salt stresses. Of key interest are plant acquisition mechanisms for nitrogen, plant potassium homeostasis, ion acquisition and homeostasis under salt stress, and the energy cost of primary flux mechanisms at the plasma membrane. The experimental approach ranges from mathematical modelling and high-precision measurement of nutrient fluxes using radiotracers, to the genetic manipulation of nutrient metabolism and acquisition, ionic and metabolic profiling of plant tissues, expression profiling of transporters, electrophysiology, respiration analysis, and field measurements and trials. The PI's laboratory is known for its investigation of the physiology of intact plants, the development of novel methods to tackle the complexities associated with whole systems, and for its effort to identify practical recommendations emerging from the mechanistic study of plant ion transport physiology.
