Physiological ecology of nutrients acquisition in terrestrial plants

PI的实验室研究陆生植物营养获取的生理生态学。它考察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，涉及以下几个领域：谷物产量潜力、森林演替、细胞离子相互作用以及干旱和盐胁迫。主要关注植物对氮的获取机制、植物钾的稳态、盐胁迫下离子的获取和稳态，以及质膜上主要通量机制的能量成本。实验方法包括数学建模和使用放射性示踪剂对营养通量的高精度测量，对营养代谢和获取的遗传操纵，植物组织的离子和代谢谱，转运体的表达谱，电生理学，呼吸分析以及现场测量和试验。PI的实验室以其对完整植物生理学的研究，解决与整个系统相关的复杂性的新方法的发展，以及从植物离子运输生理学的机制研究中确定实用建议的努力而闻名。

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.
