Soil Microbiome and Abiotic Stress Tolerance in Plants
We assessed the effect of arbuscular mycorrhizal fungi (AMF) on growth, nutrient uptake, and productivity of chickpea (Cicer arietinum), and AMF diversity in two soils in Pakistan. Soil from Bhakkar had higher nitrogen content than Khushab. Root colonisation was greater in Khushab than Bhakkar, with colonisation influencing phosphorus uptake in both regions. Glomus and Acaulospora were the most dominant genera. Chickpeas from Bhakkar had higher protein content and nutrient concentrations than Khushab. AMF colonisation increased plant moisture, fats, and carbohydrates.

We investigate the rhizospheric mycobiome of Moringa oleifera, identifying pivotal genes encoding enzymes integral to metabolic pathways, as per KEGG. Fungal taxa from Mucoromycota and Zoopagomycota, including Rhizophagus and Mucor ambiguus, harbour enzymes crucial for metabolic, genetic and environmental processes. These enzymes facilitate the biosynthesis of metabolites such as acetyl-CoA and isoleucine essential for DNA repair, energy metabolism and membrane integrity. We underscore the symbiotic relationship between fungal enzymes and Moringa roots, optimising nutrient acquisition and energy provisioning.

Iodine application reduced the deleterious effects of salinity on lettuce. Iodine affects plants in a dose-dependent manner, with low doses stimulating but high doses inhibiting. Iodine spray increased the activity of enzymatic and nonenzymatic antioxidants. Plants treated with iodine showed reduced toxic compounds such as H2O2 and malondialdehyde. Lettuce plants sprayed with iodine showed improved nutritional status and increased photosynthetic pigments. Iodine addition increased lettuce growth and yield while reducing its nitrate content

Excess amounts of salts used in agriculture lead to deterioration of crop growth and yield. This problem requires urgent, sustainable resolution. The use of soil microorganisms not only reduces salt levels but helps plants to grow under such stress. Our study revealed that applying soil microorganisms significantly improved the growth and yield of wheat under salt stress, and also enhanced soil fertility.
