  abstract = {{A}rbuscular mycorrhizal fungi ({AMF}) establish a mutualistic symbiosis with several plants and play a key role in improving plant growth, tolerance to abiotic and biotic stresses as well as the soil structure. {T}his work aimed at elucidating the {AMF} temperature stress modulating impact on four pearl millet lines plant growth and soil aggregation. {E}xperimental trials were carried out in both greenhouse and growth chamber to determine the response of the four millet lines to inoculation with two {AMF} strains ({R}hizophagus aggregatus and {F}unneliformis mosseae) under heat and non-stress conditions. {W}e first investigated the mycorrhizal colonization ({MC}) and the mycorrhizal growth response ({MGR}) of millet lines in relation with their soil aggregation potential (root adhering soil/root biomass, {MAS}/{RB}) in the greenhouse. {S}econdly, the four millet lines were grown in two separated growth chambers and subjected to a day/night temperature of 32/28 degrees {C} as the control treatment and 37/32 degrees {C} as the temperature stress treatment. {P}lant growth, mycorrhization rate and several physiological, mycorrhizal and soil parameters were measured. {R}esults showed that the mycorrhization rates of millet lines were low and not significantly different. {F}unneliformis mosseae (31.39%) showed higher root colonization than {R}hizophagus aggregatus (22.79%) and control (9.79%). {T}he temperature stress reduced the mycorrhizal colonization rate, shoot and root biomass, and the soil aggregation for all tested lines. {L}220 and {L}132 showed more {MC} rate and {MGR} than the other lines under control and high-temperature treatment. {T}he {MGR} was significantly better under temperature stress conditions than in the control. {U}nder the temperature stress conditions, inoculation with {R}. aggregatus and {F}. mosseae increased chlorophyll concentration, root dry weight and shoot dry weight as compared to non-inoculated plants. {AMF} inoculation, particularly with {F}. mosseae had a positive influence on the tolerance of millet lines to temperature stress. {T}his study demonstrates that {AMF} play an important role in the response of these four millet lines to temperature stress. {AMF} is therefore an important component in the adaptation of crops to climatic variations in {S}ub-{S}aharan {A}frica.},
