Use of the Pseudomonas sp. OBA 2.4.1 Strain for Presowing Treatment of Pea Seeds (Pisum Sativum L.) in the Presence of Heavy Metals and Glyphosate

— The results of study of the effects of the Pseudomonas sp. OBA 2.4.1 PGPB strain resistant to NiCl 2 (up to 3 mM), Pb(CH 3 COO) 2 (up to 5 mM), and glyphosate (up to 8 mg/mL) on Pisum sativum L. plants at different concentrations of the heavy metals and the herbicide are reported. It was found tha...

Description
Summary:— The results of study of the effects of the Pseudomonas sp. OBA 2.4.1 PGPB strain resistant to NiCl 2 (up to 3 mM), Pb(CH 3 COO) 2 (up to 5 mM), and glyphosate (up to 8 mg/mL) on Pisum sativum L. plants at different concentrations of the heavy metals and the herbicide are reported. It was found that this strain had a positive effect on the root length of pea seedlings in the presence of heavy metals indicating an increase in the plant resistance to nickel and lead stress. However, no such effect was observed in the experiment with glyphosate, which confirmed the high toxicity of this compound. The results obtained demonstrated that the Pseudomonas sp. OBA 2.4.1 strain promoted the growth of Pisum sativum L. under nickel and lead stress; these findings can further be used for the development of complex biopreparations intended both for the protection of agricultural plants from the effects of heavy metals and for remediation of contaminated soils.
