These derivatives were generated following homologous recombination with an internal fragment of targeted genes resulting in gene disruption by insertion of a copy of suicide vector pVIK165. The genes disrupted were F-avi5813 encoding a phosphopantetheinyltransferase, F-avi4329 encoding an aminotransferase and F-avi0838 (rirA) encoding an iron responsive transcriptional regulator. Such derivatives control crown gall on grapevines. In addition, these derivatives did not induce roots necrosis but enhanced root development and callus formation. On young stem explants, it was shown as well that the F2/5 derivatives are necrosis-negative."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biological control of crown gall disease on grapevines","description":"Derivatives of Agrobacterium vitis strain F2/5 are disclosed.
