An N-acetylglucosamine transporter required for arbuscular mycorrhizal symbioses in rice and maize
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 () mutant to be defective in early signalling. Here, we report cloning of on the basis of synteny with rice. encodes a functional homologue of the -acetylglucosamine (GlcNAc) transporter , and represents the first plasma membrane GlcNAc transporter identified from plants. In , exposure to GlcNAc activates cell signalling and virulence. Similarly, in treatment with rice wild-type but not root exudates induced transcriptome changes associated with signalling function, suggesting a requirement of NOPE1 function for presymbiotic fungal reprogramming.Research in the U.P. laboratories was supported by the Swiss National Science Foundation grants 3100A0- 104132, PP00A-110874, PP00P3-130704 and by the Gatsby Charitable Foundation grant RG60824.
