A multiplex TaqMan qPCR assay for sensitive and rapid detection of phytoplasmas infecting Rubus species
نویسندگان
چکیده
Rubus stunt is an economically important disease in the production of raspberries, blackberries, and loganberries. A fast, sensitive, and reliable diagnosis of phytoplasmas, the causal agent of the disease, is of prime importance to stop its spread by vegetative propagation and by insect vectors. Therefore, multiplex qPCR assays using TaqMan probes with different kinds of fluorophores in one reaction were developed, allowing the detection of phytoplasmas in general as well as a more specific detection of phytoplasmas belonging to group 16SrV and host DNA (either plant or insect). This assay now provides a practical tool for the screening of motherplants and monitoring the presence and distribution of phytoplasmas in Rubus plants of different geographic origins, cultivars, and cultivation systems, as well as in putative insect vectors like leafhoppers.

Development of a Multiplex TaqMan Real-Time PCR Assay for Sensitive and Rapid Detection of Phytoplasmas Infecting Rubus Species
Rubus stunt, a disease associated with phytoplasma infections in wild and cultivated Rubus species, is a major challenge in the production of raspberries, blackberries, and loganberries. Phytoplasmas are cell wall-less bacteria inhabiting the phloem and are transferred by phloem feeding insects. As the time between infection of a plant and the development of disease symptoms can take up to 1 ye...
متن کاملUniversal detection of phytoplasmas and Xylella spp. by TaqMan singleplex and multiplex real-time PCR with dual priming oligonucleotides
Phytoplasmas and Xylella spp. are bacteria that cause many economically important plant diseases worldwide. TaqMan probe-based quantitative real-time polymerase chain reaction (qPCR) assays have been utilized to universally detect phytoplasmas or Xylella fastidiosa. To develop a superior universal qPCR method, we used a dual priming oligonucleotide (DPO) with two annealing sites as a reverse pr...

Listeria monocytogenes is a species of foodborne pathogen often related to foods, such as poultry, ready-to-eat products, fruits, and vegetables. The culture method is a standard procedure for the detection of bacteria in food products. The real-time quantitative PCR (qPCR) technique can be used for the quantification of foodborne pathogens. The current research was aimed to assess...
متن کاملDevelopment of a duplex TaqMan real-time PCR for the general detection of phytoplasmas and 18S rRNA host genes in fruit trees and other plants
The detection of phytoplasmas in fruit trees and other important crops is demanded from nurseries and certification agencies. We have therefore developed an efficient assay for general detection of phytoplasmas. This duplex assay combines the phytoplasma detection with an internal control, detecting host gene 18S rRNA in the same reaction. The internal control enables the confirmation of an eff...
