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. ***

9631681詹森 这个美洲计划奖将支持理查德G。亚利桑那大学的詹森和墨西哥库埃尔纳瓦卡的墨西哥国立自治大学生物技术研究所的奥马尔·潘托贾和布朗温·巴克拉博士。本项目的目标是关注盐生植物通过钾通道对钠的生物化学和调节吸收。 这两个研究小组都对更高的植物耐盐性感兴趣，并将盐生植物Mesembryonium stack um（冰植物）中确定的机制与糖生植物中相应的机制进行比较。他们计划表征冰植物中的AKT/KAT和HKT转录物补体;研究细胞组织发育和基因的应激特异性表达;表征悬浮培养细胞和爪蟾卵母细胞中表达的通道/转运蛋白;并研究蛋白质对外部刺激和药理学试剂的反应。 联合工作将是互补的，并为学生和研究人员提供一个机会，探索与每个实验室相关的概念和技术。 ***
