9728907 Watson Several environmental factors influence the growth and development of green plants, but among them light is perhaps the most important. Apart from its role as the energy source for photosynthesis, light provides crucial environmental cues that control virtually every stage of the plant life cycle, from seed germination, through stem and leaf development, to flowering. The long-term goal of this research is to understand how the perception and transduction of light signals regulate the growth and development of green plants. The research will focus on two protein kinases and their genes from the garden pea. Protein kinases are ubiquitous enzymes that are frequently involved in signal transduction processes. One of the kinases under study is predicted to be a blue light photoreceptor, while the other is likely to be involved in signal transduction. A combination of genetic, molecular, and biochemical approaches is proposed to test these hypotheses, and thereby elucidate the roles of these two protein kinases in transducing light signals. This work will contribute to and expand our understanding of the fundamental mechanisms by which light regulates plant development.

几种环境因素影响绿色植物的生长和发育，但其中光线可能是最重要的。除了作为光合作用的能量来源外，光还提供了至关重要的环境线索，几乎控制着植物生命周期的每个阶段，从种子发芽，到茎叶发育，再到开花。本研究的长期目标是了解光信号的感知和转导如何调节绿色植物的生长发育。这项研究将集中在两种蛋白激酶及其基因上。蛋白激酶是一种普遍存在的酶，经常参与信号转导过程。其中一种正在研究的激酶被预测为蓝光光感受器，而另一种可能参与信号转导。遗传学，分子和生化方法的组合被提出来测试这些假设，从而阐明这两种蛋白激酶在转导光信号中的作用。这项工作将有助于并扩大我们对光调节植物发育的基本机制的理解。
