They are more intertwined than we believe. This can be directed by helping the plant produce beneficial compounds that do not allow infections / repel infestation causing insects, or indirectly by strengthening the plant with better nutrient assimilation and stronger growth responses. They boost the crop’s immunity in resisting infection. As a consequence, the exploitation of microbial potentials for plant-based biotechnological applications has been critical, especially for the development of improved phytoremediation methodologies and their outputs in contaminated areas. Microorganisms play a crucial role in plants’ growth and survival by forming symbiotic relationships that can trigger a wide range of responses to edaphic–environmental constraints. While many members of the rhizosphere microbiome are beneficial to plant growth, also plant pathogenic microorganisms colonize the rhizosphere striving to break through the protective microbial shield and to overcome the innate plant defense mechanisms in order to cause disease. Microorganisms have a range of direct effects on plants through, e.g., manipulation of hormone signaling and protection against pathogens. 36, Ujagar Industrial Estate, W.T.
