Phytophthora infestans: The notorious plant destroyer is a master manipulator

FEATURED FIGURE CAPTION:  Live imaging of Phytophthora infestans (magenta) growing on Nicotiana benthamiana cells (cyan). Cells that are colonized by the pathogen show increased numbers of vesicles (bright cyan dots) compared to cells that haven’t been colonized yet. Petre, Contreras, et al. investigate…
