The balance between rhizosphere carboxylates and arbuscular mycorrhizal symbiosis in wheat phosphorus acquisition.

ABSTRACT:

Background

Changes in plant growth and root traits in wheat (Triticum aestivum L.) vary depending on the level of phosphorus (P) supply. Two important strategies for P acquisition in wheat are the release of carboxylates into the rhizosphere and the presence of arbuscular mycorrhizal fungi (AMF). However, the relationship between root exudates and P concentration in the shoot and root, as well as the role of AMF in this process, is not yet fully understood. This study was conducted utilizing three P supply rates (0, 50, and 200 mg P kg^-1 soil) in conjunction with AMF inoculation. We examined the effects of AMF on amount of rhizosphere carboxylates and plant P uptake for nine P contrasting wheat genotypes.

Results

AMF decreased carboxylates, root biomass, root P co
