biostudies-literatureUnknown9(11)Kumar SThe present study was carried out in a pot experiment to examine the bioefficacy of three biocontrol agents, viz., <i>Trichoderma viride</i>, <i>Bacillus subtilis</i>, and <i>Pseudomonas fluorescens</i>, either alone or in consortium, on plant growth promotion and activation of defense responses in potato against the early blight pathogen <i>Alternaria solani</i>. The results demonstrate significant enhancement in growth parameters in plants bioprimed with the triple-microbe consortium compared to other treatments. In potato, the disease incidence percentage was significantly reduced in plants treated with the triple-microbe consortium compared to untreated control plants challenged with <i>A. solani</i>. Potato tubers treated with the consortium and challenged with pathogen showed signifiHeliyone22148https://www.ebi.ac.uk/biostudies/studies/S-EPMC10692827biostudies-literatureMicrobial consortium mediated acceleration of the defense response in potato against <i>Alternaria solani</i> through prodigious inflation in phenylpropanoid derivatives and redox homeostasis.PMC10692827Meena MSudhir IBehera LChandra RKeswani CSingh SKumar SfalseMicrobial consortium mediated acceleration of the defense response in potato against <i>Alternaria solani</i> through prodigious inflation in phenylpropanoid derivatives and redox homeostasis.The present study was carried out in a pot experiment to examine the bioefficacy of three biocontrol agents, viz., <i>Trichoderma viride</i>, <i>Bacillus subtilis</i>, and <i>Pseudomonas fluorescens</i>, either alone or in consortium, on plant growth promotion and activation of defense responses in potato against the early blight pathogen <i>Alternaria solani</i>.
