Climate change enhances stress in food crops. Recently, abiotic stress such as metalloid toxicity, salinity, and drought have increased in food crops. Mycorrhizal fungi can accumulate several nutrients within their hyphae through a symbiotic relationship and release them to cells in the root of the food crops under stress conditions. We have studied arbuscular mycorrhizal fungi (AMF)-enriched biofertilizers as a climate-smart technology option to increase safe and healthy food production under abiotic stress. AMF such as ., ., , , , and enhance growth and yield in food crops grown in soils under abiotic stress. AMF also works as a bioremediation material in food crops grown in soil. More precisely, the arsenic concentrations in grains decrease by 57% with AMF application. In addition, AMF increases mineral contents, and antioxidant activities under drought and salinity stress in food crops. Catalase (CAT) and ascorbate peroxidase (APX) increased by 45% and 70% in AMF-treated plants under drought stress. AMF-enriched biofertilizers are used in crop fields like precision agriculture to reduce the demand for chemical fertilizers. Subsequently, AMF-enriched climate-smart biofertilizers increase nutritional quality by reducing abiotic stress in food crops grown in soils. Consequently, a climate resilience environment might be developed using AMF-enriched biofertilizers for sustainable livelihood.
气候变化加剧了粮食作物面临的压力。最近，粮食作物中诸如类金属毒性、盐度和干旱等非生物胁迫有所增加。菌根真菌可以通过共生关系在其菌丝内积累多种养分，并在胁迫条件下将它们释放到粮食作物根部的细胞中。我们研究了富含丛枝菌根真菌（AMF）的生物肥料，将其作为一种气候智能型技术选项，以在非生物胁迫下增加安全健康的粮食产量。诸如...、...、...、...、...和...等AMF可促进在非生物胁迫土壤中种植的粮食作物的生长并提高产量。AMF在种植于土壤中的粮食作物中还可作为一种生物修复材料。更确切地说，施用AMF后谷物中的砷含量降低了57%。此外，AMF可增加粮食作物在干旱和盐度胁迫下的矿物质含量及抗氧化活性。在干旱胁迫下，经AMF处理的植株中过氧化氢酶（CAT）和抗坏血酸过氧化物酶（APX）分别增加了45%和70%。富含AMF的生物肥料被用于精准农业等农田中，以减少对化肥的需求。随后，富含AMF的气候智能型生物肥料通过减轻种植于土壤中的粮食作物的非生物胁迫来提高营养品质。因此，使用富含AMF的生物肥料或许可以营造一个具备气候适应能力的环境，以实现可持续生计。
