Abstract

Pathogenic microbes manipulate their plant host by interfering with a plethora of cellular processes (Asai & Shirasu, 2015; Pelgrom & Van den Ackerveken, 2016). To hijack the cellular machinery of the plant, pathogens deliver effector proteins inside host cells by mechanisms that are often not fully understood. In this issue of New Phytologist, Wang et al. (pp. 205–215) provide convincing, live cell-imaging footage of the delivery into plant cells of a host-translocated RXLR effector by the oomycete pathogen Phytophthora infestans. The late blight pathogen deploys an unconventional protein secretion route for this. Together with recent live cell-imaging data on effector traffic in other plant– pathogen interactions, discussed later, we have begun to grasp that invading filamentous microbes use unconventional secretory routes to deliver their sabotage tools into plant cells.
