Jing et al. reveal how danger-associated peptides inhibit root growth in plants in response to pathogen attack. Plant Cell (2018) https://doi.org/10.1105/tpc.18.00145. Background: Plants defend themselves against pathogens and pests through an innate immune system that is activated by pathogen-associated and damage/danger-associated signals. Immunity often occurs at the expense of growth inhibition, as exemplified by […]
