Just like animals and human beings, plants also accommodate a countless number of microorganisms as hosts.Microorganisms enjoy this hospitality by developing an interaction with the plants either in a synergistic waybenefiting each other or in an antagonistic manner damaging their hosts. Such types of mutualistic and pathogenicinteractions also take place among microbial community. Proteins, metabolites and certain molecular mechanismsdetermine whether the intruder is a symbiotic or pathogenic microorganism. Various bacteria and fungi interactsymbiotically and play significant role in plant growth promotion. Certain species of fungi, oomycetes, bacteria andnematodes are also pathogenic in nature and cause impact on soil and plant. Soil serves as a big substrate formicrobial community, which are important in a number of ways owing to their role in mineralization, nutrientavailability and are sources of industrial products such as enzymes, hormones, antibiotics, vitamins etc. This reviewwill improve our understanding about relationships between plants and their microbial friends and foes. Themechanisms adopted by soil microbes to contribute in the betterment of soil leading towards enhanced plant growthas well as pathogenicity caused by these microbes have also been discussed. Recent advances to recognize themolecular mechanisms involved in such interactions have also been discussed. Recent advances made in this fieldand the areas needing further research have also been mentioned.
