We have previously shown that the effector protein MiSSP7 (Mycorrhiza-induced Small Secreted Protein 7) encoded by <italic>L. bicolor</italic> is necessary for the establishment of symbiosis with host trees, although the mechanistic reasoning behind this role was unknown. We demonstrate here that MiSSP7 interacts with the host protein PtJAZ6, a negative regulator of jasmonic acid (JA)-induced gene regulation in <italic>Populus.</italic> As with other characterized JASMONATE ZIM-DOMAIN (JAZ) proteins, PtJAZ6 interacts with PtCOI1 in the presence of the JA mimic coronatine, and PtJAZ6 is degraded in plant tissues after JA treatment. The association between MiSSP7 and PtJAZ6 is able to protect PtJAZ6 from this JA-induced degradation. Furthermore, MiSSP7 is able to block—or mitigate—the impact of JA on <italic>L. bicolor</italic> colonization of host roots. We show that the loss of MiSSP7 production by <italic>L. bicolor</italic> can be complemented by transgenically varying the transcription of <italic>PtJAZ6</italic> or through inhibition of JA-induced gene regulation. We conclude that <italic>L. bicolor</italic>, in contrast to arbuscular mycorrhizal fungi and biotrophic pathogens, promotes mutualism by blocking JA action through the interaction of MiSSP7 with PtJAZ6.</p></abstract><kwd-group><kwd>ectomycorrhizal fungus</kwd><kwd>defense</kwd><kwd>tree nutrition</kwd><kwd>host immunity</kwd><kwd>plant hormone</kwd></kwd-group><counts><page-count count="6"></page-count></counts></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
