Primers designed for the detection of grapevine pathogens spreading with propagating material by quantitative real-time PCR
Published April 12, 2015

Several grapevine pathogens are disseminated by propagating material as systemic, but latent infections. Their detection and identification have a basic importance in the production and handling of propagating stocks. Thus several sensitive and reliable diagnostic protocols mostly based on molecular techniques have been developed. Of these meth...ods quantitative real-time PCR (q-PCR) has recently got an emerging importance. Here we collected primer data for the detection and identification of grapevine pathogens which are important in the production of propagating stocks by q-PCR. Additional novel techniques that use DNA amplification, hybridization and  sequencing are also briefly reviewed.

Conventional PCR primers for the detection of grapevine pathogens disseminated by propagating material
Published September 7, 2014

Polymerase chain reaction driven by sequence specific primers has become the most widely used diagnostic method to detect and identify plant pathogens. The sensitive and cost-effective pathogen detection is exceptionally important in the production of propagating material. In this paper we have collected primer sequence data from the literature... for the detection of the most important grapevine pathogens disseminated by propagating stocks by conventional polymerase chain reaction. Basic protocols to obtain template nucleic acids have also been briefly rewieved.

Detection and identification of phytoplasmas in peach based on woody indexing and molecular methods
Published March 21, 2001

Symptoms resembling phytoplasma disease have been observed on peach trees in a seed-source plantation of stone fruits in south Hungary quite recently. In this publication we report on the results of woody indexing of symptomatic peach trees on GF 305 indicator in the field and under greenhouse conditions as well as on molecular studies. Phytopl...asma infection detected on GF 305 indicators in greenhouse and field indexing was confirmed by PCR. Nested PCR was conducted using universal primer pairs followed by group and subgroup specific primers for the second amplification. RFLP analysis of nested PCR products was performed using Rsal restriction enzyme. Based on the results of molecular studies it can be concluded that phytoplasmas, belonging to the European stone fruit yellows subgroup (16SrX-B) were identified in peach trees. Further studies on symptomatic peach trees originating from different parts of Hungary are in progress.
