The Effects of Expressing a Plant Elicitor Peptide on Nematode Infection on Soybean.

There is a pressing need to develop alternative management strategies for the soybean cyst nematode (), the most costly pathogen to soybeans. Plant elicitor peptides (PEPs), which are produced by plants in response to stress and stimulate broad-spectrum disease resistance, were previously shown to reduce soybean cyst nematode infection on soybeans when applied as a seed treatment. Here, we introduce an alternative method to deliver PEPs to soybean using a common plant growth-promoting rhizobacterium, , as a bacterial expression system.
