    ..Together, these results suggest that AM fungus induced a defense response against RKN in the mycorrhizal grapevine roots, which appeared to involve transcriptional control of VCH3 expression throughout the whole root tissue...

The Soybean Rhg1 locus for resistance to the soybean cyst nematode Heterodera glycines regulates the expression of a large number of stress- and defense-related genes in degenerating feeding cells. Plant Physiol. 2011;155:1960-75 pubmed publisher
    ..Our study demonstrates that a network of molecular events take place during Rhg1-mediated resistance, leading to a highly complex defense response against a root pathogen...
