Abstract The heavy metals present in the environment accumulate in the plants
and affect their productivity and yield. By entering the food chain, metals cause
several serious health problems in human beings as well as in other organisms.
Indole acetic acid (IAA) is known to act as a signaling molecule between symbiotic
association of metal accumulating plants and plant growth promoting rhizobacteria
(PGPR). Present study demonstrated a protective role of IAA against surplus Zinc
(Zn)-induced toxicity to Hordeum vulgare seedlings. Elevated Zn concentrations
suppressed the plant growth, caused a reduction in leaf relative water contents
