The research will use flouorescent dye markers to investigate the potential pathways for movement of water-soluble compounds between green leaf cells, which produce water-soluble photosynthetic compounds such as sugars and amino acids, and the vascular cells which distribute the photosynthetically produced compounds throughout the plant. Experimental treatments will be devised to modulate or disrupt the flow of dye between leaf cells and the vascular system. A comparison will then be made of the effects of these treatments on the recovery of photosynthetically produced compounds such as sugars and amino acids in the vascular system. The results should reveal which photosynthetically-produced solutes are delivered to the vascular cells and also the route that these solutes take as they move from the leaf tissues and into the vascular cells.

这项研究将使用荧光染料标记来调查 水溶性化合物在 绿色叶细胞，产生水溶性光合化合物 如糖和氨基酸，以及分布在血管中的血管细胞， 光合作用产生的化合物遍布整个植物。 将设计实验性的治疗方法来调节或破坏血流 叶细胞和维管系统之间的染料。 比较将 然后由这些治疗对恢复的影响， 光合作用产生的化合物，如糖和氨基酸， 血管系统 结果应该揭示哪些光合作用产生的溶质是 输送到血管细胞，这些溶质 它们从叶片组织进入维管细胞。
