9314225 Franceschi This award will provide travel support over the next three years to enable Dr. Vincent Franceschi of Washington State University to make yearly visits to conduct cooperative research with Dr. John W. Patrick at the University of Newcastle in Australia. The research will focus on the mechanism of sucrose unloading in developing seeds. To understand how unloading is regulated, it is necessary to analyze each step at the cellular and subcellular level, and is best accomplished through a histochemical approach. Specialized cells called transfer cells appear to contain the biochemical mechanisms necessary for controlling sucrose unloading. Antibody and cDNA probes will be used to further characterize the transfer cells. This project will bring together the physiological expertise of Dr. Patrick with the molecular probes and techniques which have been developed by Dr. Franceschi. Since crop yield is strongly affected by the rate and pattern of import into storage regions of a plant, and unloading is central to import, this research could have significant practical importance in agriculture.

9314225 Franceschi该奖项将在未来三年提供旅费支持，使华盛顿州立大学的Vincent Franceschi博士每年访问澳大利亚纽卡斯尔大学，与John W. Patrick博士进行合作研究。本研究将重点探讨种子发育过程中蔗糖卸载的机理。为了理解卸荷是如何调控的，有必要在细胞和亚细胞水平上分析每个步骤，并且最好通过组织化学方法来完成。被称为转移细胞的特化细胞似乎包含控制蔗糖卸载所必需的生化机制。抗体和cDNA探针将用于进一步表征转移细胞。这个项目将把帕特里克博士的生理学专业知识与弗兰切斯基博士开发的分子探针和技术结合起来。由于作物产量受到植物储存区进口的速度和模式的强烈影响，而卸货是进口的核心，因此该研究可能在农业上具有重要的实际意义。
