During arbuscular mycorrhizal (AM) symbiosis, the plant gains access to phosphate (Pi) and nitrogen delivered by its fungal symbiont. Transfer of mineral nutrients occurs at interface between branched hyphae called arbuscules root cortical cells. In Medicago truncatula, a Pi transporter, PT4, is required for symbiotic transport, in pt4, transport fails, degenerate prematurely, symbiosis not maintained. Premature arbuscule degeneration (PAD) suppressed when pt4 mutants are nitrogen-deprived,...
Arbuscular mycorrhizal (AM) symbiosis is a mutually beneficial association of plants and fungi the subphylum Glomeromycotina. Endosymbiotic AM colonize inner cortical cells roots, where they form branched hyphae called arbuscules that function in nutrient exchange with plant. To support arbuscule development subsequent bidirectional exchange, root undergo substantial transcriptional reprogramming. REDUCED ARBUSCULAR MYCORRHIZA1 (RAM1), previously studied several dicot plant species, major...
Arbuscular mycorrhizal (AM) symbiosis is accompanied by alterations to root cell metabolism and physiology, the pathways of orthophosphate (Pi) entry into root, which increase with Pi delivery cortical cells via arbuscules. How AM influences content response dynamics in cortex epidermis unknown. Using fluorescence resonance energy transfer (FRET)-based biosensors, we mapped relative cytosolic plastidic Brachypodium distachyon cells, analyzed responses extracellular traced extraradical...

Abstract Arbuscular mycorrhizal (AM) symbiosis is a mutually beneficial association of plants and fungi the sub-phylum Glomeromycotina. The endosymbiotic AM colonize inner cortical cells roots, where they form branched hyphae called arbuscules that function in nutrient exchange with plant. To support arbuscule development subsequently bidirectional exchange, root undergo substantial transcriptional re-programming.

The symbiosis between crops and arbuscular mycorrhizal fungi (AMF) have become an attractive route towards achieving carbon neutral agriculture reducing the use of chemical fertilizers. Yet, our understanding how active AMF infections influence uptake, allocation, exchange is limited. Here, we combine X-ray CT PET imaging to observe quantify flow from leaves roots hyphae. Comparison maize grown with without allows us measure changes in amount 11CO2 taken up subsequently 11C allocated...
