In addition to its important role as a source of energy for photosynthesis, light plays an extremely important role in the regulation of plant development. While much is known about the phytochrome system, responsive to wavelengths at the red end of the electromagnetic spectrum, little is known about photoreceptors or their signal transduction chains at the blue end. The investigator proposes to continue investigating a blue light mediated phosphorylation of a plasma membrane protein that is hypothesized to be involved in phototropism and perhaps other blue light responses. They plan to purify and characterize the protein and other proteins which may interact with it in photoreception and early signal transduction. Studies of the system at the gene level will be initiated by cloning and sequencing the genes encoding for these proteins. Elucidation of this system at the cell, biochemical and molecular levels should be a major step forward in our understanding of how light regulates plant development.

除了作为能源的重要作用外， 在光合作用中，光起着极其重要的作用。 调节植物的发育。 虽然我们知道很多关于 光敏色素系统，响应于在红端的波长， 电磁波谱，对光感受器知之甚少 或者它们的信号传导链在蓝色末端。 的 调查人员建议继续调查蓝光 介导的质膜蛋白磷酸化， 假设参与向光性，也许其他蓝色 光反应。 他们计划对这种蛋白质进行纯化和鉴定 以及其他可能在光感受中与其相互作用的蛋白质， 早期信号转导 基因水平的系统研究 将通过克隆和测序编码 这些蛋白质。 在细胞中阐明该系统， 生物化学和分子水平应该是一个重大的进步， 我们对光如何调节植物发育的理解。
