Title : Rhizobium spp and Pseudomonas fluorescents promote growth and alleviate salt stress in Arabidopsis thaliana
Abstract:
Application of rhizobacteria (Rhizobium leguminosarum 1, Sinorhizobium meliloti, Pseudomonas fluorescens PF.64 and Pseudomonas fluorescens BB.10) induced a change in phenotype and root architecture of Arabidopsis thaliana (Col-0) under abiotic stress (Salinity stress, 120 mM). Plants treated with rhizobacteria and sodium chloride showed symptoms between purple, yellowing and wilting, whereas plants treated with NaCl alone could not survive. These beneficial bacteria did not stimulate growth under no stress situation, but their effect was stronger against salt stress with induction of tolerance (90-100%).
