Abstract
Abstract Arbuscular mycorrhizal fungi (AMF), particularly the Glomerales group, play a paramount role in plant nutrient uptake, and abiotic and biotic stress management in rice, but recent evidence revealed that elevated CO 2 concentration considerably reduces the Glomerales group in soil. In view of this, the present study was initiated to understand the interaction effect of native Glomerales species application in rice plants ( cv . Naveen) under elevated CO 2 concentrations (400 ± 10, 550 ± 20, and 700 ± 20 ppm) in open‐top chambers. Three different modes of application of the AMF inoculum were evaluated, of which, combined application of AMF at the seedling production and transplanting stages showed increased AMF colonization, which significantly improved grain yield by 25.08% and also increased uptake of phosphorus by 18.2% and nitrogen by 49.5%, as observed at 700‐ppm CO 2 concentration. Organic acids secretion in rice root increased in AMF‐inoculated plants exposed to 700‐ppm CO 2 concentration. To understand the overall effect of CO 2 elevation on AMF interaction with the rice plant, principal component and partial least square regression analysis were performed, which found both positive and negative responses under elevated CO 2 concentration.
