Regulation of Flavonoid Biosynthesis by Plastid-derived Signals (C06)

黄酮类化合物（如花青素）的积累是植物适应强光和冷环境以及叶绿体发育受到干扰的主要生理特性。虽然已经确定了参与该途径转录调控的因素，但涉及叶绿体作为环境变化传感器调节类黄酮生物合成的信号转导级联的组成部分尚不清楚。这项工作的主要目的是了解叶绿体衍生的信号对叶绿体发育过程中黄酮类生物合成的调节以及对光强和温度变化的响应的影响。

As a major physiological trait of high light and cold acclimation as well as in response to perturbed chloroplast development, plants accumulate flavonoids (e.g., anthocyanins). Although factors involved in transcriptional regulation of the pathway have been identified, the components of signal transduction cascade(s) involving chloroplast as a sensor for the changing environment to regulate flavonoid biosynthesis are not understood. The main objective of the proposed work is to understand the impact of chloroplast derived signals on the regulation of flavonoid biosynthesis during chloroplast development and in response to shifts in light intensity and temperature.
