Leveraging Bacterial Endophytes as Bio-fertilizer Products

Event Details

Endophytes are microorganism that live within plant tissues not causing harm. Bacterial endophytes often possess capabilities that can benefit the host plant such as nitrogen fixation, solubilization of recalcitrant phosphate, decreasing stress responses through the production of 1-aminocyclopropane-1-carboxylate (ACC) deaminase, the production of plant hormones like indole-3-acetic acid (IAA), or suppressing the growth of pathogenic fungi. The production of ammonia and ammonium phosphate fertilizers are polluting processes highly energy intensive, and the run-off of over fertilization can cause dead zones in rivers, lakes, and gulfs. The goal of these studies was to examine 20 bacterial endophytes isolated from Brassica carinatafor their plant growth promoting capabilities and their possible use as bio-fertilizers to decrease the input requirements of nitrogen and phosphorus. We conducted in vitroassays to determine the bacterial endophytes’ plant growth promoting capabilities. We also conducted several in plantaexperiments from short root architecture trials, to greenhouse and field trials. Our research explores some of the many bacterial endophyte abilities to decrease abiotic and biotic stresses on plants.
