Heavy metal contamination of soils is a complex process and several conventional physicochemical methods are being used to remediate the metal-contaminated soils which are costly, less efficient and are not applicable for large systems [21]. Use of phytohormone-producing heavy metal-tolerant plant growth-promoting rhizobacteria (PGPR) is considered as alternate strategy to decontaminate heavy metal polluted soils that is more efficient, inexpensive, sustainable, and ecofriendly approach [22; 23; 24]. The PGPR produce phytohormones in addition to several other growth-promoting traits that can reduce the heavy metal toxicity and improve crop growth under heavy metal polluted soil conditions [25; 26]. Phytohormone-producing Cd-tolerant PGPR can be effective to induce resistance against heavy metal toxicity in crop plants. The Cd-tolerant PGPR strains help to reduce Cd uptake of crop plants by stabilizing it in the soil through production of exopolysaccharide-charides [27; 28]. Scientists have reported several Cd-tolerant PGPR strains belonging to different genera [16; 18; 29; 30]. These strains have multifarious plant growth promoting (PGP) traits in additions to phytohormone producing ability [31; 32] thus can be used to develop biofertilizer to grow vegetables and other crops on metal contaminated soils. Although, inoculation with PGPR may enhance the uptake and translocation of heavy metals in plants as reported by [PERSON] et al. [33], the inoculation with Cd-tolerant PGPR can, however, be used as an effective strategy to reduce the uptake and translocation of Cd to above ground parts [34]. Recently, [PERSON] et al. [35] reported that Cd-tolerant PGPR in combination with hydroxyapatite helped in the immobilization of Cd in soil thus reducing their uptake. They argued that enhanced sequestration of Cd in soil was due to production of phytohormones, siderophores and polymeric substances. [PERSON] et al. [32] reported that _Enterobacter_ sp. MN17 inoculation on seed in combination with gravel sand and biochar resulted in a significant improvement in nutritional quality of _Pisum sativum_ by reducing the Cd uptake. They suggested the combined use of _Enterobacter_ sp. MN17, gravel sand, and biochar as an effective approach to grow pea and other vegetables under Cd-contaminated soils. Siderophore-producing, heavy metal tolerant PGPR can accelerate bioavailability and accumulation of nutrients in plants and thus help to reduce the deleterious effects of heavy metals on plants. Inoculation with phytohormone-producing, metal tolerant bacterial strains _Bacillus cereus_ and _Pseudomonas moraviensis_ decreased the toxic effects of heavy metals on wheat growth under saline sonic soil conditions [36]. Keeping in view the above facts, we hypothesized that IAA and EPS-producing rhizobacterial strains may induce Cd tolerance in _Brassica juncea_ by retrieving the negative impacts caused by Cd-stress. In our previous studies [37], it has been established that the strains FN13, FN14 and FN16 have the ability to phytostabilize Cd in contaminated soil due to accumulation of Cd in their bodies along with production of IAA, EPS, and siderophores. Therefore, the present study was conducted to evaluate the efficacy of these strains on growth, physiological alterations, biochemical constituents, and Cd tolerance in _Brassica juncea_ (L.) under artificially Cd-spiked soil.
