10.22376/ijpbs.2019.10.1.p1-12 Volume 9 Issue 3 2018 (July-September) Cadmium toxicity in crop plants is one of the major concerns and is responsible for the loss in yields. This investigation analyses the role of a common PGPR lessThan i greaterThan Pseudomonas fluorescens lessThan /i greaterThan , in alleviating cadmium stress in lessThan i greaterThan Vigna radiata lessThan /i greaterThan seedlings. The seedlings were exposed to Cd stress at different levels i.e. 0, 100 and 200 ppm and physiological response was observed in PGPR treated and untreated plants. The growth and biomass of mung bean seedlings were reduced to considerable extent whereas MDA content increased with exposure to increasing cadmium concentrations. Treatment with lessThan i greaterThan P. fluorescence lessThan /i greaterThan showed remarkable improvement in growth, biomass and production of stress combating metabolites proline and flavonoids, and reduced MDA content. The study showed that the ameliorative effects of lessThan i greaterThan P. fluorescens lessThan /i greaterThan involved the prevention of H lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 2 lessThan /sub greaterThan accumulation in mung bean shoots, which is an important signaling molecule produced during Cd stress.
