Ayling, S.Smith, S.Smith, F.Kolesik, P.2006-07-212006-07-211997Plant and Soil, 1997; 196(2):305-3100032-079X1573-5036http://hdl.handle.net/2440/13092The roots of most plants form symbiotic associations with mycorrhizal fungi. The net flux of nutrients, particularly phosphorus (P), from the soil into the plant is greater in mycorrhizal than in comparable non-mycorrhizal plants. However despite the widespread occurrence of mycorrhizal associations the processes controlling the transfer of solutes between the symbionts are poorly understood. To understand the mechanisms regulating the transfer of solutes information about conditions at the interface between plant and fungus is needed. Measurements of apoplastic and intracellular electrical potential difference in leek roots colonised by mycorrhizal fungi and estimates of cytosolic pH in fungal hyphae are presented. These and the implications for plant/fungal mineral nutrition in vesicular-arbuscular mycorrhizas are discussed.en©1997 Kluwer Academic Publishers.Allium porrum L.BCECFcytoplasmic pHelectric potential differenceleekmycorrhizaJournal article0030003805001997014010.1023/A:1004284326231A1997YJ926000222-s2.0-003072927767811
