This project will define roles of chloroplast pigments in cellular signaling, plant growth and development. Effective communication between the chloroplast and the nucleus is essential for maintaining viability and productivity of the cell. Similarly, long-distance signaling is required for coordinated growth and development and we hypothesise that pigments also have importance in this role. Our proposal brings together the multidisciplinary skills and resources of six investigators to define how certain carotenoids and chlorophyll precursors regulate gene expression and to determine the identity of what is most likely a carotenoid derivative with hormonal properties that controls lateral branch growth.

该项目将定义叶绿体色素在细胞信号传导、植物生长和发育中的作用。叶绿体和细胞核之间的有效通讯对于维持细胞的活力和生产力至关重要。同样，协调生长和发育需要长距离信号传导，我们假设色素在这一作用中也很重要。我们的提案汇集了六名研究人员的多学科技能和资源，以定义某些类胡萝卜素和叶绿素前体如何调节基因表达，并确定最有可能具有控制侧枝生长的激素特性的类胡萝卜素衍生物的身份。
