Translocated signals regulating stem cell (meristem) activity in legumes

韧皮部和木质部的运输通道将营养物质分配给生长中的植物器官。它们还通过传递信号来调节器官之间的交流，这些信号会引起对发育和环境提示的反应。最重要的信号转导部位是根和地上部顶端分生组织的干细胞。该项目将使用代谢组/蛋白质组方法并依靠羽扇豆素允许收集运输液体的独特功能来发现和识别这些信号。该项目将确定修改信号作用的方法，以提高豆科作物的表现。

Translocation channels of phloem and xylem allocate nutrients to growing plant organs. They also mediate communication between organs through transport of signals that elicit responses to developmental and environmental cues. The most important sites for signal transduction are the stem cells of root and shoot apical meristems. This project will discover and identify these signals using a metabolomic/proteomic approach and relying on a unique feature of lupin that permits collection of transport fluids. The project will identify ways to modify signal action to enhance performance of legumes.
