Asexual Propagation of Grapevine Transmits Pierce’s Disease Pathogen (Xylella fastidiosa) to Rooted Cuttings

摘要: ABSTRACTAn objective of this study was to investigate rooting success grape cuttings propagated from vines symptomatic Pierce’s disease. Additional objectives were assess if rooted could survive and produce viable plants, determine Xylella fastidiosa (causal agent disease) be found in cuttings. In Jan. 2008, taken asymptomatic ‘Merlot’ ‘Cabernet Sauvignon’ grapevines growing the Hill Country Gulf Coast regions Texas. Six weeks after propagated, each cutting uprooted evaluated for infection parameters. Cuttings then planted containers held greenhouse evaluate survivability. To confirm presence X. fastidiosa, tested by real-time polymerase chain reaction. Data indicate several positive appeared healthy. Therefore, infected with have ability p...
