This project will use a molecular genetic approach in garden pea to investigate the roles of photoreceptors that mediate developmental responses to light. It will define gene families encoding phytochrome, cryptochrome and phototropin photoreceptors, characterise photoreceptor gene expression, and identify mutants with impaired response to light. The mutants will be used in molecular, physiological and biochemical studies to examine how photoreceptors control and co-ordinate development throughout the plant via effects on plant hormone synthesis and response. Results from the project will be of practical importance in manipulating key aspects of plant growth to better suit particular environmental and agronomic objectives.

该项目将使用分子遗传学方法在豌豆中研究光感受器在调节发育对光的反应中所起的作用。它将定义编码光敏色素、隐色素和光敏受体的基因家族，表征光感受器基因的表达，并识别对光反应受损的突变体。这些突变体将被用于分子、生理和生化研究，以研究光感受器如何通过影响植物激素的合成和反应来控制和协调整个植物的发育。该项目的结果将在操纵植物生长的关键方面以更好地适应特定的环境和农学目标方面具有实际意义。
