Suppression of Sclerotium rolfsii and Fusarium oxysporum through Glomalin a Glycoprotein Produced by Arbuscular Mycorrhizal Fungi under in vitro Condition

Abstract

For sustainable agriculture to succeed, especially in the production of organic food, the use of biofertilizers and biopesticides is essential. Arbuscular mycorrhizal symbiosis is important for improving plant development through increased nutrient intake, soil stabilization, and carbon sequestration through the creation of glomalin, a distinct and specialized protein. It was not determined whether glomalin affects soil-borne fungi infections. Therefore, using glomalin isolated from the soil used to raise maize plants inoculated with various arbuscular mycorrhizal fungi (AMF), the inhibition of soil-borne plant diseases Sclerotium rolfsii and Fusarium oxysporum was examined. The outcomes demonstrated that there was variation in the quantity of glomalin generated by various AMF species. Glomalin isolated from soil inoculated with Glomus coronatum suppressed Sclerotium rolfsii and Fusarium oxysporum more effectively in in-vitro tests than soil inoculated with Glomus intraradices and Glomus mosseae.
