"US- Spain Cooperative Research: From Source to Target: A Collaborative Search for the Signal"

0305647 Hannapel这个为期两年的奖项授予美国和西班牙在植物分子遗传学方面的合作，获奖者包括爱荷华州立大学的David Hannapel和西班牙马德里大学CSIC校区国家生物技术中心的Salome Prat-Monguio。该项目的目标是以马铃薯块茎为模型，研究植物营养生长的分子控制。该项目将确定这一信号通路中源和目标之间的潜在联系，以及从叶片到目标顶端分生组织的信号传递机制。该项目将侧重于源器官和靶器官在不同发育阶段暴露于诱导条件下的微阵列分析。这位美国研究人员在合作中带来了转录因子及其相互作用的伙伴在调节信号通路目标器官中的细胞生长方面的专业知识。西班牙研究人员在源器官固有的光感知、信号产生和运输机制方面的专业知识补充了这一点。这家西班牙集团在光周期调控和植物激素在发育中的作用方面拥有领先的专业知识。合作的结果预计将改善对信号机制的理解，这些机制将优化世界重要粮食作物的生长。

0305647HannapelThis two-year award for US-Spanish collaboration in plant molecular genetics involves David Hannapel of Iowa State University and Salome Prat-Monguio at the National Center of Biotechnology at the CSIC Campus of the University of Madrid, Spain. The objectives of the project are to study the molecular controls for vegetative growth of plants using tuberization of potato as a model. The project will identify potential connections between source and target in this signaling pathway, and the mechanism for signal transmission from leaf to the target apical meristem. The project will focus on microarray analysis in both source and target organs exposed to inductive conditions over discrete developmental stages. The US researcher brings to the collaboration expertise in the role of transcription factors and their interacting partners in regulating cell growth in target organs of a signaling pathway. This is complemented by the Spanish researcher's expertise in the mechanism of light perception, signal production, and transport inherent in the source organ. The Spanish group has leading expertise in photoperiodic regulation and the role of phytohormones in development. The results of the collaboration are expected to an improved understanding of signaling mechanisms that would optimize growth in a significant world food crop.
