Plant growth-promoting microorganisms: New insights and the way forward

Abstract

In the context of global challenges such as climate change, soil degradation, and food security, understanding the modes of action of Plant Growth-Promoting Microorganisms (PGPMs), their formulation, and their application is crucial and can be more focused in future research projects. This editorial paper aims to elucidate diverse modes of action employed by different types of PGPMs, including nitrogen fixation, phosphorus solubilization, production or regulation of phytohormones, and plant protection against environmental and biotic stresses as demonstrated and discussed in the Special Issue entitled "Plant Growth-Promoting Microorganisms: new insights and the way forward".
