Explanation:
Arsenic (As) pollution, particularly in soil and water, is a very prominent environmental issue which seriously threatens plant growth, development, and productivity. Since As is ubiquitous in the natural environment, microorganisms have developed mechanisms to resist the toxic effects of this metalloid. A large number of microorganisms, viz. Acinetobacter, Aeromonas, Bacillus, Exiguobacterium, and Pseudomonas, are capable of growing in the presence of high concentrations of As.

But relatively less information is available on accumulation, mobilization, distribution, and speciation of As by rhizospheric microbiota and their impact on plant growth and development.
