Phosphoproteomics of Marchantia polymorpha upon Blue light and DCMU treatments

To optimize growth and development, plants monitor photosynthetic activities and regulate various cellular processes accordingly. However, signaling mechanisms that coordinate plant growth with photosynthesis remain poorly understood. To identify factors that are involved in this coordination, we performed a phosphoproteomic analysis with Marchantia polymorpha, an extant bryophyte species in the basal lineage of land plants.

为优化生长与发育进程，植物会监测自身光合活性，并据此调控各类细胞生理过程。然而，协调植物生长与光合作用的信号传导机制仍未得到充分阐释。为鉴定参与该协调过程的关键因子，本研究以现存陆生植物基部类群的苔藓植物（bryophyte）物种地钱（Marchantia polymorpha）为实验材料，开展了磷酸化蛋白质组学分析。
