Abstract

Mycorrhizal colonization may influence the composition or diversity of mycorrhizal associated bacterial (MAB) communities in mycorrhizosphere and stimulate the plant growth via. different types of mechanisms. MAB populations can have an impact on the interactions or the development of plants. These communities can be directly or indirectly influenced by mycorrhiza or the combined effects on the survival of the stressand harsh environment. We conclude that some MABs are multifunctional and actively encourage regulators to create a multifunctional mechanism to stimulate growth and trigger mycorrhizal activities.This review article shows different possible contributions of various mycorrhizal fungi and MAB in the advancement of nutrient management in sustainable agriculture.

Key words: Mycorrhizal fungi; rhizobacteria; MAB; plant growth promotion
