Abstract excerpt
Arbuscular mycorrhizal (AM) fungi enhance plant nutrition and stress tolerance, yet their agricultural use remains limited because symbiotic outcomes are unpredictable. Mycorrhizal responsiveness (AM-responsiveness)-the host's growth response to AMF inoculation-offers a potential breeding target. We investigated variation in AM-responsiveness among Petunia hybrida, P. axillaris, P. exserta and P. inflata, and...
