Introduction: Plants do not grow in isolation, rather they are hosts to a variety of microbes
in their natural environments. While, few thrive in the plants for their own benefit, others may have a
direct impact on plants in a symbiotic manner. Unraveling plant-microbe interactions is a critical
component in recognizing the positive and negative impacts of microbes on plants. Also, by affecting
the environment around plants, microbes may indirectly influence plants. The progress in sequencing
technologies in the genomics era and several omics tools has accelerated in biological science. Studying
the complex nature of plant-microbe interactions can offer several strategies to increase the
productivity of plants in an environmentally friendly manner by providing better insights. This review
brings forward the recent works performed in building omics strategies that decipher the interactions
between plant-microbiome. At the same time, it further explores other associated mutually beneficial
aspects of plant-microbe interactions such as plant growth promotion, nitrogen fixation, stress suppressions
in crops and bioremediation; as well as provides better insights on metabolic interactions between
microbes and plants through omics approaches. It also aims to explore advances in the study of
Arabidopsis as an important avenue to serve as a baseline tool to create models that help in scrutinizing
various factors that contribute to the elaborate relationship between plants and microbes. Causal
relationships between plants and microbes can be established through systematic gnotobiotic experimental
studies to test hypotheses on biologically derived interactions.
Conclusion: This review will cover recent advances in the study of plant-microbe interactions keeping
in view the advantages of these interactions in improving nutrient uptake and plant health.
