The reaction of pepper breeding lines under organic production conditions to Verticillium wilt, viruses and phytoplasma was observed at Maritsa Vegetable Crop Research Institute, Plovdiv, Bulgaria during two successive years. diseases severity recorded, when symptoms dahliae, Phytoplasma were deeply expressed. dahliae attack index for early varied widely from 15.04% line O58/14 43.83% O26/16. F...

background: the witches’ broom disease of lime caused by candidatus phytoplasma aurantifolia, is the most devastating disease of acidian lime in the southern parts of iran. objectives: at present, no effient method has been developed for controlling the disease, therefore quarantine approaches such as early detection and subsequent eradication of infected trees is very important. toward this ...

The bacterial genus "Candidatus Phytoplasma" contains a group of insect-transmitted plant pathogens in the class Mollicutes. Here, we report a draft genome assembly and annotation of strain NCHU2014, which belongs to the 16SrII-A subgroup within this genus and is associated with purple coneflower witches' broom disease in Taiwan.

We report here the draft genome sequence of a Dyella-like bacterium (DLB) isolated from Hyalesthes obsoletus, the insect vector of the uncultivable mollicute bacterium "Candidatus Phytoplasma." This isolate inhibits Spiroplasma melliferum, a cultivable mollicute. The draft genome of DLB consists of 4,196,214 bp, with a 68.6% G+C content, and 3,757 genes were predicted.

Paulownia witches' broom (PaWB) disease caused by phytoplasma is a fatal disease that leads to considerable economic losses. Although there are a few reports describing studies of PaWB pathogenesis, the molecular mechanisms underlying phytoplasma pathogenicity in Paulownia trees remain uncharacterized. In this study, after building a transcriptome database containing 67,177 sequences, we used i...

Witches' broom disease of lime (WBDL), caused by 'Candidatus Phytoplasma aurantifolia', is a very serious disease of acid limes. The disease destroyed more than one million lime trees in the Middle East. WBDL results in the production of small, clustered leaves in some branches of lime trees. Branches develop symptoms with time and become unproductive, until the whole tree collapses within 4-8 ...

Background and Aims Maize bushy stunt phytoplasma (MBSP) is a bacterial pathogen of maize ( Zea mays L.) across Latin America. MBSP belongs to the 16SrI-B sub-group within the genus ' Candidatus Phytoplasma'. MBSP and its insect vector Dalbulus maidis (Hemiptera: Cicadellidae) are restricted to maize; both are thought to have coevolved with maize during its domestication from a teosinte-like an...

Phytoplasmas are bacterial plant pathogens that can affect different vegetal hosts. In South America, a phytoplasma belonging to ribosomal subgroup 16SrIII-J has been reported in many crops. Here we report its genomic draft sequence, showing a total length of 687,253 bp and a G+C content of 27.72%.

Phytoplasmas are unculturable plant-pathogenic bacteria causing devastating damage to agricultural production worldwide. Here, we report the draft genome sequence of "Candidatus Phytoplasma asteris" strain OY-V. Most of the known virulence factors and host-interacting proteins were conserved in OY-V. This genome furthers our understanding of genetic diversity and pathogenicity of phytoplasmas.
