With
current state of knowledge, this review focuses on recent
advancements in functional roles of PGPB in chromiumstressed
soils in accelerating growth and development of plants
and phytoremediation of chromium in tandem. Other heavy
metals have been excluded from this discussion as chromium
and its derivatives are the most commonly detected metal contaminants
at the polluted sites and produce pronounced mutagenic
and carcinogenic effects on organisms even at low
concentration (100 lg kg1)
