Efficacy of the biological control agent Rhizobium vitis ARK-1 against tumorigenic Rhizobium vitis, the causal agent of grapevine crown gall
Grapevine crown gall causes significant economic damage in vineyards and nurseries worldwide. Infected vines are not curable due to irreversible genomic transformation by the tumorigenic bacterium Rhizobium vitis. Crown gall results in a gradual decline in yield and vine vigor, then the complete …

Leaf galls in our native trees and shrubs
Plant galls constitute a branch of study and research which has been to me a subject of much interest for some time. At the start of this work, it was intended to include Plant galls in general, but after some months this was found to be too comprehensive a field and would in fact take a great many …

Biological Control Agent Rhizobium vitis, ARK-1 Reduces Incidence and Severity of Grapevine Crown Gall in Virginia
Crown gall of grapevine (Vitis spp.) is a serious and economically important disease caused by the bacterial pathogen Rhizobium vitis, which transforms healthy plant cell genomes leading to hypertrophic and hyperplastic growth of affected plant cells. Recent studies have documented a strong …

Hypersensitive Response in Live Oak: Characterization and Efficacy Against a Host of Specific Gall-Forming Wasp
… in response to oviposition by the host specific gall-forming wasp Belonocnema treatae to assess whether apparent HR functions in plateau live oak as a plant defense, and if so, to estimate its importance. To do this I examined the probability of gall establishment in the presence and absence of …

Agrobacterium-mediated gene transfer into kiwifruit
… the establishment of Agrobacterium-mediated transformation for new plant species. A series of binary vectors have been constructed that express a chimaeric β-D-glucuronidase (GUS) gene in plants cells but not in bacterial cells. This feature allows GUS activity from transformed plant cells to be …

Eco-physiological and molecular manipulation of leaf-level primary and secondary metabolism by arthropod herbivory
… the grape-phylloxera system to reveal that the gall-forming insect parasite phylloxera induces functional stomata and globally reconfigures plant metabolism at the genomic level to enhance insect fitness. Although insect-induced stomata are rare in nature, the transcriptional pattern of gall …
