'Candidatus Phytoplasma mali', 'Candidatus Phytoplasma pyri' and 'Candidatus Phytoplasma prunorum', the causal agents of apple proliferation, pear decline and European stone fruit yellows, respectively.
Apple proliferation (AP), pear decline (PD) and European stone fruit yellows (ESFY) are among the most economically important plant diseases that are caused by phytoplasmas. Phylogenetic analyses revealed that the 16S rDNA sequences of strains of each of these pathogens were identical or nearly identical. Differences between the three phytoplasmas ranged from 1.0 to 1.5% of nucleotide positions...
متن کاملCandidate insect vectors of apple proliferation in Northwest Spain
The apple proliferation (AP) disease is spread mostly by two psyllids. Each species plays a predominant role as AP vector that changes regionally. Thus, there is an urgent need to identify the AP vectors in each region where the disease is present. This research aimed at identifying the psyllid community in apple orchards from Asturias (NW Spain) and studying their possible role in AP transmiss...
متن کاملA real-time PCR method for detection and quantification of ‘Candidatus Phytoplasma prunorum’ in its natural hosts
A real-time PCR assay conjugated with the fluorescent SYBR Green I dye has been developed for rapid, sensitive and quantitative detection of ‘Candidatus Phytoplasma prunorum’ in its natural hosts, in stone fruits such as apricot plants and in the insect vector Cacopsylla pruni. The selected primers amplified specifically a fragment 153 bp long from the rplV (rpl22) gene of ‘Ca. P. prunorum’ and...
متن کاملComparison of different techniques for inoculation of "Candidatus Phytoplasma mali" on apple and periwinkle in biological indexing procedure.
As phytoplasmas are non cultivable micro-organisms, the research on phytoplasmal diseases can only be achieved with infected hosts. Biological indexing (by grafting) is the simplest detection method for phytoplasmal diseases. We tested four different grafting techniques for inoculation of apple trees or periwinkles in greenhouse, including whip graft, bark graft, budding and chip-budding. All t...
متن کامل‘Candidatus Phytoplasma mali’: the current situation of insect vectors in northwestern Italy
The two acknowledged vectors of ‘Candidatus Phytoplasma mali’ in north-western Italy, the psyllid Cacopsylla melanoneura and the leafhopper Fieberiella florii, have been compared to highlight their role in the apple proliferation epidemiology in relation to their infectivity, transmission efficiency and permanence in apple orchards and in wild vegetation, predominantly hawthorn formations. The ...
