Plants usually produce secondary metabolites to tolerate metal toxicity. Present study was designed to explore the phytoremediation potential of\n                    <jats:italic>Vigna radiata<\/jats:italic>\n                    var. NM-II in the presence of metal resistant PGPB and comparison of metabolites produced under heavy metal stresses (Pb, Ni, Cr). Three PGPB selected for present study include\n                    <jats:italic>Bacillus pumilus<\/jats:italic>\n                    MB246,\n                    <jats:italic>Serratia nematodiphila<\/jats:italic>\n                    MB307\n                    <jats:italic>and Delftia Lacustris<\/jats:italic>\n                    MB322. Pot experiments were conducted with inoculated\n                    <jats:italic>V<\/jats:italic>\n                    .\n                    <jats:italic>radiata<\/jats:italic>\n                    NM-II seeds grown in soil artificially contaminated with lead (Pb), Nickle (Ni) and chromium (Cr) at a concentration of 300, 200 and 100 mg\/kg respectively. After harvesting various growth parameters were studied (root length, shoot length, fresh weight and dry weight). Bacterial colonization on root surfaces of harvested plants was observed through Scanning electron microscopy (SEM) and Elemental composition was recorded through Energy dispersive X-ray spectroscopy (EDX) attached with SEM. Metabolic response of harvested plants was studied through Gas chromatography Mass spectrophotometry (GC-MS) analysis. Metal accumulation in roots, shoots and soil was analysed by acid digestion method from which Bioaccumulation factor (BF) and Translocation factor (TF) of metal from soil to plant was calculated. Results revealed stimulatory effect of PGPB on growth and phytoextraction ability of\n                    <jats:italic>V<\/jats:italic>\n                    .\n                    <jats:italic>radiata<\/jats:italic>\n                    . Soil metal removal efficiency was in the order Pb&gt;Ni&gt;Cr, whereas metal distribution in each part of plant was root&gt;stem&gt;leaf. The BF and TF values suggested\n                    <jats:italic>V<\/jats:italic>\n                    .\n                    <jats:italic>radiata<\/jats:italic>\n                    as Pb and Ni excluder while moderate accumulator for Cr. Elemental analysis through Energy Dispersive X- ray spectroscopy (EDX) found potassium (K\n                    <jats:sup>+<\/jats:sup>\n                    )and calcium (Ca\n                    <jats:sup>+<\/jats:sup>\n                    )as highly abundant nutrients with least accumulation of sulphur (S). Metabolites study through GC-MS revealed variety of compounds (carbohydrates, amino acids, fatty acids, steroids etc) detected differentially under each metal treatment and their concentration was influenced by different bacterial inoculations. Overall 9-Octadecenamide was found as commonly present lipid compound in most of the treatments which is required for detoxification in plants. The study concluded beneficial role of PGPB for successful phytoremediation of heavy metals and differential response of metabolites towards each metal stress that is related to metal tolerance ability of\n                    <jats:italic>V<\/jats:italic>\n                    .\n                    <jats:italic>radiata<\/jats:italic>\n                    .\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0277101","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T13:35:14Z","timestamp":1668087314000},"page":"e0277101","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":25,"title":["Metabolites produced by inoculated Vigna radiata during bacterial assisted phytoremediation of Pb, Ni and Cr polluted soil"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7932-4646","authenticated-orcid":true,"given":"Uzma","family":"Zulfiqar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Azra","family":"Yasmin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anila","family":"Fariq","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"issue":"3","key":"pone.0277101.ref001","doi-asserted-by":"crossref","first-page":"200","DOI":"10.1080\/15226514.2018.1501334","article-title":"Effect of plant growth promoting bacterium; Pseudomonas putida UW4 inoculation on phytoremediation efficacy of monoculture and mixed culture of selected plant species for PAH and lead spiked soils","volume":"21","author":"SL Afegbua","year":"2019","journal-title":"Int.
