What is it about?
Plant pathogens living in soild must move to host plants for infection. They can sense compounds excreted from plants, beheviorally respond to them and move toward plants. In this study, we found bacterial sensor and its ligand (L-malate) involved in plant infection by a plant pathogen.

Why is it important?
Moving to plants is the eraliest stage of plant infection. Elucidation of its molecular mechanism helps developimg a novel, environmentally friendly method to control plant infection by soil plant pathogens (i.e. no use of pesticides).
Perspectives
This is the first step to understand molecular biology of chemotaxis toward plants in soil plant pathogens. We would like to draw an precise, detailed, entire picture about "what happens in the earliest atep of plant infection".
