0305414SchachtmanThis U.S.-Mexico award will support Dr. Daniel Schachtman of the Donald Danforth Plant Science Center in St. Louis, Missouri, in a research collaboration with Dr. Bronwyn J. Barkla of the Universidad Nacional Autonoma de Mexico (UNAM) in Cuernavaca, Morelos, Mexico. The researchers intend to work on several transport proteins (KUPs) that are involved in potassium uptake and cellular equilibrium. Potassium is an essential mineral for both animal and plant nutrition. Plants require large quantities of this mineral, which they acquire through root uptake from soils. Several families of transporters are involved in moving potassium into cells and around the plant. The KUPs (potassium uptake permeases) are a major family of proteins involved in potassium uptake into cells, a process that drives cell expansion and plant development. The proposed collaboration will focus on methods for the membrane localization of the KUP proteins, an important objective since little is known about which membranes these proteins are located on. The knowledge gained will help to understand their function fully. The collaborators will benefit from the Mexican lab's expertise in plant membrane transporter biochemistry and the St. Louis lab's expertise in plant molecular and cell biology. A postdoctoral fellow and a student will take part in the exchange and will be trained in membrane biochemistry.

0305414Schachtman 该美国-墨西哥奖项将支持密苏里州圣路易斯唐纳德丹福斯植物科学中心的 Daniel Schachtman 博士与墨西哥莫雷洛斯州库埃纳瓦卡墨西哥国立自治大学 (UNAM) 的 Bronwyn J. Barkla 博士进行研究合作。 研究人员打算研究几种参与钾吸收和细胞平衡的转运蛋白（KUP）。钾是动物和植物营养的必需矿物质。 植物需要大量的这种矿物质，它们通过根部从土壤中吸收来获得这些矿物质。 几个转运蛋白家族参与将钾转移到细胞和植物周围。 KUP（钾吸收渗透酶）是参与细胞吸收钾的主要蛋白质家族，该过程驱动细胞扩张和植物发育。 拟议的合作将重点研究 KUP 蛋白的膜定位方法，这是一个重要的目标，因为人们对这些蛋白位于哪些膜上知之甚少。 获得的知识将有助于充分理解它们的功能。合作者将受益于墨西哥实验室在植物膜转运蛋白生物化学方面的专业知识和圣路易斯实验室在植物分子和细胞生物学方面的专业知识。一名博士后和一名学生将参加交流，并接受膜生物化学方面的培训。
