“…They are formed by bryophytes, pteridophytes, gymnosperms and angiosperms and are ubiquitous in most temperate and tropical ecosystems including agricultural systems. According to Sui et al 18 , legumes have a good mycotrophic status and arbuscular mycorrhizas are found in their roots. The fungal partners in AM associations are remarkably abundant, accounting for 5-50% of the microbial biomass in agricultural soils, with the fungal phylum, Glomeromycota being the most common 19 .…”

Background and Objective: Cowpea (Vigna unguiculata (L.) Walp., is well-adapted to the Northern parts of Nigeria than the Southern Region especially the Niger Delta Region of Nigeria. The aim of this study was to investigate the adaptive capabilities of cowpea in crude oil-contaminated and non-contaminated soils. Materials and Methods: Two varieties of cowpea namely TVU-31 and Aloka bean were planted in crude oil-contaminated and un-contaminated soils in three replicates using the randomized complete block design for a 50 days period. Data was collected for vegetative vigor, agronomic parameters and root nodulation. The fungal species associated with the roots were isolated using Yeast Extract Mannitol Agar (YEMA) media and later subcultured in Potato Dextrose Agar Medium (PDA) media for identification. Results: The two cowpea varieties, had intermediate vegetative vigor and a gradual increase in the plant height, root length, root width and number of nodules. From the root architecture, it was observed, that the cowpea varieties in the contaminated soil had more adventitious roots with smaller diameters, shallower basal roots with longer, denser root hairs and higher root biomass than the varieties in the un-contaminated soil. Seven fungal species namely Penicillium chrysogenum, Botryodiplodia the obromae, Mucor circinelloides, Aspergillus flavus, Aspergillus spp., Neurospora spp. and Aspergillus niger) were identified to associate with the roots of cowpea. Conclusion: This study, therefore, provides preliminary data for further research into the adaptive capabilities of cowpea in Nigeria.

“…These results are similar to mycorrhizal colonization rates of L. chinensis , P. distans , and A. adurgens in the present study, which are 25.00%, 16.89%, and 46.95%, respectively. Among them, the mycorrhizal colonization rate of A. adurgens was higher than that of the other two grasses, which may be due to the fact that the mycorrhizal colonization rate of AMF and legume plants is generally higher than that of gramineous plants (Sui et al, 2022). In this study, AMF significantly improved the biomass of A. adsurgens , indicating that the symbiosis of AMF and A. adsurgens effectively alleviated the phytotoxicity caused by Cd and salt during plant growth.…”

Differential effects of arbuscular mycorrhizal fungi on three salt‐tolerant grasses under cadmium and salt stress

et al. 2022

Salt‐tolerant plants generally grow in salty conditions, and some of them are also tolerant to heavy metal stress. Arbuscular mycorrhizal fungi (AMF) can help plants withstand abiotic stresses. However, few studies have focused on the effects of AMF on the growth of salt‐tolerant plants in cadmium (Cd)‐contaminated saline soils. In this study, a greenhouse pot experiment was conducted to investigate the effects of AMF (Funneliformis mosseae) on growth, ion uptake, and Na+ and Cd translocation in three salt‐tolerant grasses (Leymus chinensis, Puccinellia distans, and Astragalus adsurgens) in a Cd‐contaminated saline soil. The regulation of genes by AMF in A. adsurgens was also explored by transcriptome analysis. The results showed that AMF increased the biomass of A. adsurgens but not that of L. chinensis and P. distans. AMF promoted phosphorus (P) uptake from soil and improved shoot K+: Na+ ratio, but it decreased shoot Na+ and Cd concentrations and their translocation rates in A. adsurgens. Transcriptome analysis showed that AMF upregulated the differentially expressed genes (DEGs) encoding cytokinins, which may be linked to the increase in shoot biomass in inoculated A. adsurgens, but downregulated the DEGs related to light harvest, suggesting avoidance of photodamage. AMF downregulated the DEGs in the pathways of the cell wall and those associated with antioxidant enzymes. These results suggest that AMF symbiosis in A. adsurgens effectively alleviates the Na+ and Cd toxicity of shoots. This study implies the potential to use salt‐tolerant grasses in association with AMF to rehabilitate the heavy metal‐contaminated saline ecosystems.

Fungus-based biofertilizers, in particular, have been shown to improve plant growth and health by providing essential nutrients and improving soil health. Arbuscular mycorrhizal fungi (AMF) form mutualistic symbiotic relationships with plants, including those in the Solanaceae family. They colonize the root systems of plants and aid in enhancing nutrient absorption efficiency, particularly in phosphorus-deficient soils. The present study was carried out to study the interaction between Solanum melongena L. with Glomus macrocarpum and Funneliformis mosseae (formely known as Glomus mosseae) at transcript level. In this study a total of 365 transcripts were upregulated (>1.5x) folds in S. melongena in response to both the fungi, while 44 transcripts were upregulated only in response to G. macrocarpum and 28 transcripts were upregulated only in response to F. mosseae. Similarly, 49 transcripts were downregulated less than -1.5 folds in response to both the fungi while 78 were downregulated only in response to the G. macrocarpum and 36 were downregulated only in response to F. mosseae. KEGG pathway analysis of S. melongena treated with G. macrocarpum revealed carbon metabolism, cofactor biosynthesis and Endocytosis as the dominant metabolic pathway, while analysis of the F. mosseae treatment revealed Glycerophospholipid and Endocytosis metabolism as dominant metabolic pathways.
