Proteomic response of the early divergent liverwort Marchantia polymorpha during infection with the oomycete pathogen Phytophthora palmivora

Here, we define the proteomic response of the early divergent liverwort Marchantia polymorpha during infection with the oomycete pathogen Phytophthora palmivora. We sampled whole liverwort thalli that were mock-inoculated (water) or infected with P. palmivora zoospores at 4 and 8 days post inoculation (dpi). This analysis revealed the protein profiles of liverworts during the biotrophic (4 dpi) and necrotrophic (8 dpi) stages of pathogen infection. In combination with additional omics datasets, our analyses reveal conserved aspects in the molecular response to pathogen infection in liverworts and angiosperms.

本研究解析了早期分化的地钱（Marchantia polymorpha）在感染卵菌病原菌棕榈疫霉（Phytophthora palmivora）过程中的蛋白质组响应。我们采集了经空白接种（无菌水处理）或接种棕榈疫霉游动孢子的完整地钱叶状体，采样时间为接种后4天和8天（dpi）。本分析揭示了地钱在病原菌感染的活体营养型（接种后4 dpi）与死体营养型（接种后8 dpi）阶段的蛋白质表达谱。结合其他多组学数据集，本研究的分析结果揭示了地钱与被子植物在应对病原菌感染的分子响应中所共有的保守特征。
