My research is focused on the use of plant growth-promoting rhizobacteria (PGPR) for promoting plant growth, plant health, and nutrient uptake. The emphasis is on various species and strains of the spore-forming bacilli because spores of these PGPR remain viable as seed treatments for a long period of time, thereby increasing the opportunities of integrating the PGPR into current agricultural practices. Modes of action are studied, and effects on plant pathogens as well as plant-damaging insects are evaluated in collaborations with other faculty in the College of Agriculture at Auburn University.
