Editorial: Molecular markers of plant adaptation to multiple environmental stressors

Environmental stressors impair plant growth, cause the shift in root microbiome community and alter 16 the root exudates composition (Ali et al., 2022;Chai and Schachtman, 2022). Among beneficial 17 microorganisms, rhizobia and arbuscular mycorrhiza fungi (AMF) improve plant tolerance to abiotic 18 stress by modulating water uptake, nutrient assimilation, antioxidative response and photosynthesis 19 performance (Ali et al., 2023). While the effectiveness of environmentally friendly approaches to 20 preserve soil fertility is still emerging, it seems that their application is a suitable replacement for 21 conventional agriculture. Manihot esculenta roots showed differential accumulation of metabolites related to nitrogen 82 assimilation and cellular metabolism, including 5-aminolevulinic acid, L-glutamic acid, and lysoPC 83 18:2. They reported the differentially expressed genes related to nutrient transport, hormone signaling, 84 sugar metabolism, and symbiosis signaling pathways as a result of AMF inoculation. 85 Four articles of this Research Topic bring to scientific community advanced techniques, including 86 transcriptomic reprograming, short-term cultivation of highly adapted phosphorous fungi, hormonal 87 regulation, root exudates metabolomic analysis, phenotyping of root system, and root hair 88 development. All of them are promising tools for efficient N uptake and excellent solutions against the 89 overuse of synthetic N fertilizers, which are the significant source of greenhouse gas emissions. 90
