Light is an important cue with which plants monitor their environment to trigger adaptive growth responses. Photoreceptors, such as the phytochromes, are the “eyes” of the plants, which can sense direction, quality and quantity of the light. PhyA, the light-instable form of phytochromes, is special because it mediates responses to different light conditions, both the very low fluences (VLFR) and high irradiances (HIR). The aim of our work is to further our understanding of the PhyA-dependent VLFR and to further elucidate its biological and biochemical function as an important modulator of plant development. OWL1, isolated in our lab as the first protein specific for the VLFR pathway, will be used as a molecular tool with which to dissect the signal transduction pathway. Furthermore, we aim to isolate additional components of the pathway. The knowledge of the components of the pathway is a prerequisite to understand the signaling network leading to the physiological changes observed.

光是植物监测其环境以触发适应性生长反应的重要线索。光感受器，如光敏色素，是植物的“眼睛”，可以感知光的方向，质量和数量。PhyA是光敏色素的光不稳定形式，其特殊性在于它介导对不同光条件的响应，包括极低能量密度（VLFR）和高辐照度（HIR）。我们的工作的目的是进一步了解PhyA依赖的VLFR，并进一步阐明其作为植物发育的重要调节剂的生物学和生化功能。OWL1，在我们的实验室中分离的第一个蛋白质特异性的VLFR途径，将被用作一个分子工具来剖析信号转导途径。此外，我们的目标是分离途径的其他组件。了解该途径的组成部分是理解导致观察到的生理变化的信号网络的先决条件。
