An N-acetylglucosamine transporter required for arbuscular mycorrhizal symbioses in rice and maize

Résumé

Most terrestrial plants, including crops, engage in beneficial interactions with arbuscular mycorrhizal fungi. Vital to the association is mutual recognition involving the release of diffusible signals into the rhizosphere. Previously, we identified the maize no perception 1 (nope1) mutant to be defective in early signaling. Here, we report cloning of ZmNOPE1 on the basis of synteny with rice. NOPE1 encodes a functional homolog of the Candida albicans N-acetylglucosamine (GlcNAc) transporter NGT1, and represents the first plasma membrane GlcNAc transporter identified from plants. In C. albicans, exposure to GlcNAc activates cell signaling and virulence. Similarly, in Rhizophagus irregularis treatment with rice wild type but not nope1 root exudates induced transcriptome changes associated with signaling function, suggesting a requirement of NOPE1 function for presymbiotic fungal reprogramming.
