Heavy metals (HMs) exert a negative impact on physiological processes in plants, which can adversely affect the productivity of agricultural crops. In this experiment, we assessed potential to mitigate toxic effects HMs soft wheat through use rhizospheric microorganisms from genus Azospirillum. initial phase identified most resistant Azospirillum strains Cu (from 1.5 15 mg/L), Ni 2 20 and Pb 15.9 159.4 mg/L). Both significantly inhibited bacterial growth induced substantial oxidative stress majority studied strains. The strain A. picis B-2897T exhibited highest resistance all HMs. cultivation soil supplemented with led an increased rate enhanced productivity. Conversely, reduced by 65% 27%, respectively. This was accompanied chlorophyll depletion decrease expression genes NDOR GST, are involved xenobiotic detoxification. Pre-inoculation seeds HM concentration plant seedlings; particular, level 0.005% below detectable (i.e., 0.001%), 0.014% 0.008%. bacteria stimulated responsible for detoxification contributed wheat. Thus, be utilized as bioproduct alleviate
