Trans-Graft Protection Against Pierce's Disease Mediated by Transgenic Grapevine Rootstocks.

A field study showed that transgenic grapevine rootstocks can provide trans-graft-mediated protection to a wild type scion against Pierce's disease (PD) development. We individually field-tested two distinct strategies. The first expressed a chimeric antimicrobial protein (CAP) that targeted the functionality of the lipopolysaccharide (LPS) surface of (), the causative agent of PD.
