The fi rst of the fastidious prokaryotic plant pathogens to be grown in axenic culture was the phloem-limited Spiroplasma citri, which causes stubborn disease of citrus. Other fastidious prokaryotic plant pathogens followed and include Spiroplasma kunkelii (corn stunt) and Spiroplasma phoeniceum (periwinkle yellows). The vast majority of spiroplasmas are associated with arthropods and do not ca...
Droplet digital polymerase chain reaction (ddPCR) is a method for performing digital PCR that is based on water-oil emulsion droplet technology. It is a unique approach to measure the absolute copy number of nucleic acid targets without the need of external standards. This study evaluated the applicability of ddPCR as a quantitative detection tool for the Spiroplasma citri, causal agent of citr...
Spiroplasma citri, a phloem-limited pathogen, causes citrus stubborn disease (CSD). Losses due to CSD in California orchards have grown over the past decade. To investigate the possibility of introduction or emergence of a new strain, a study of genetic diversity among S. citri strains from various locations was conducted using random amplified polymorphism DNA-polymerase chain reaction (RAPD-P...
