Control of Photoassimilate Transport in Source Leaves

这项研究将使用荧光染料标记来研究水溶性化合物在绿叶细胞和维管细胞之间的潜在移动路径，绿叶细胞产生糖和氨基酸等水溶性光合作用化合物，维管细胞将光合作用产生的化合物分布在植物各处。将设计实验性的治疗方法来调节或干扰叶细胞和维管系统之间的染料流动。然后将比较这些处理对光合作用产生的化合物(如血管系统中的糖和氨基酸)的恢复的影响。结果应该揭示哪些光合作用产生的溶质被输送到维管细胞，以及这些溶质从叶片组织进入维管细胞时所走的路线。

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.
