説明
<jats:title>Significance</jats:title> <jats:p> Plants use the hormone jasmonic acid (JA) to modulate plant:microbe interactions. Disease-causing microbes use proteins to alter host JA signaling to aid their growth in plant tissues. Beneficial symbiotic fungi, which colonize plant tissues and provide essential ecosystem services such as carbon sequestration and plant fertilization, can also alter JA signaling in plant cells to promote colonization. Here, we demonstrate that the MiSSP7 (Mycorrhiza-induced small secreted protein-7) protein of the beneficial fungus <jats:italic>Laccaria bicolor</jats:italic> interacts with host plant JA signaling repressors and, in contrast to biotrophic pathogens, promotes symbiosis by blocking JA action. These results shed new light on how beneficial and pathogenic microbes have evolutionarily diverged in the mechanisms by which they overcome plant defenses. </jats:p>
