Abstract excerpt
A Lycopersicon esculentum mutant (rmc) is resistant to colonization by most arbuscular mycorrhizal fungi (AMF), but one Glomus intraradices isolate (WFVAM 23) develops arbuscules and vesicles in the rmc cortex. It is unknown whether the symbiotic phosphate (Pi)-uptake pathway is operational in this interaction. Hyphal uptake of (32)Pi and expression of plant Pi transporter genes were investigated in the rmc...
