U.S.-Mexico Cooperative Research: Uptake and Transport of Sodium in a Halophyte

9631681 Jensen该美洲项目奖将支持亚利桑那大学的Richard G.Jensen博士与墨西哥库尔纳瓦卡国立自治大学生物技术研究所的Omar Pantoja博士和Bronwyn Barkla博士之间的合作研究。本项目的目标是研究盐生植物通过钾通道对钠的生化和调节吸收。这两个研究小组都对更高的植物耐盐性感兴趣，并比较盐生植物中发现的中胚花结晶藻(冰草)的机制与糖类植物中的相应机制。他们计划研究AKT/KAT和HKT转录本在冰草中的互补；研究细胞-组织发育和应激基因的特异性表达；鉴定悬浮培养细胞和非洲爪哇卵母细胞中表达的通道/转运蛋白；以及研究蛋白质对外部刺激和药物的反应。联合工作将是相辅相成的，并为学生和研究人员提供机会来探索与每个实验室相关的概念和技术。***

9631681 Jensen This Americas Program award will support collaborative research between Dr. Richard G. Jensen of the University of Arizona and Drs. Omar Pantoja and Bronwyn Barkla of the Instituto de Biotecnologia of the Universidad Nacional Autonoma de Mexico (UNAM) in Cuernavaca, Mexico. The objective of this project is to focus on the biochemical and regulatory uptake of sodium through potassium channels of halophytic plants. The two research groups share an interest in higher plant salinity tolerance, and in comparing mechanisms identified in the halophyte Mesembryanthemum crystallinum (ice plant) with corresponding mechanisms in glycophytes. They plan to characterize the AKT/KAT and HKT transcript complement in the ice plant; study cell-tissue development and stress specific expression of genes; characterize the channel/transporter proteins expressed in suspension culture cells and in Xenopus oocytes; and investigate protein responses to external stimuli and pharmacological agents. The joint work will be complementary and offer an opportunity for students and researchers to explore concepts and techniques relevant to each laboratory. ***
