E6 – PHYLOGENETIC CLASSIFICATION OF PLANT PATHOGENIC MYCOPLASMA-LIKE ORGANISMS OR PHYTOPLASMAS
A Glucosinolate Metabolism Pathway in Living Plant Cells Mediates Broad-Spectrum Antifungal Defense
It is proposed that reiterated enzymatic cycles, controlling the generation of toxic molecules and their detoxification, enable the recruitment of glucosinolates in defense responses.
Detection of the apple proliferation and pear decline phytoplasmas by PCR amplification of ribosomal and nonribosomal DNA.
Results show that it is not possible to detect all strains of the AP and PD phytoplasmas, respectively, with pathogen-specific primers.
'Candidatus Phytoplasma mali', 'Candidatus Phytoplasma pyri' and 'Candidatus Phytoplasma prunorum', the causal agents of apple proliferation, pear decline and European stone fruit yellows,…
It can be concluded that the AP, PD and ESFY phytoplasmas are coherent but discrete taxa that can be distinguished at the putative species level, for which the names 'Candidatus Phytoplasma mali, 'Candidia Phy toplasma pyri' and 'candidatusPhytopLasma prunorum', respectively, are proposed.
Taxonomic relatedness and phylogenetic positions of phytoplasmas associated with diseases of faba bean, sunnhemp, sesame, soybean, and eggplant
The linear chromosome of the plant-pathogenic mycoplasma 'Candidatus Phytoplasma mali'
The small linear chromosome with large terminal inverted repeats and covalently closed hairpin ends, the extremely low GC content and the limited metabolic capabilities reflect unique features of 'Ca.
'Candidatus Phytoplasma', a taxon for the wall-less, non-helical prokaryotes that colonize plant phloem and insects.
The trivial name 'phytoplasma' has been adopted to collectively name wall-less, non-helical prokaryotes that colonize plant phloem and insects, which were formerly known as mycoplasma-like organisms.…
Detection and genetic relatedness of phytoplasmas associated with plant diseases in Thailand
Spacer region sequence analysis showed that the 3 groups of phytoplasmas formed distinct phylogenetic clusters, and within the white leaf cluster, SCWL and SCGS were more closely related to each other than they were to BGWL and CGWL.
Classification of plant-pathogenic mycoplasma-like organisms using restriction-site analysis of PCR-amplified 16S rDNA
Summary: A method has been developed to amplify the 16S rRNA gene of plant-pathogenic mycoplasma-like organisms (MLOs) from infected plant material using the polymerase chain reaction (PCR). The…
Symbiotic Streptomycetes provide antibiotic combination prophylaxis for wasp offspring.
The complementary action of all symbiont-produced antibiotics confers a potent antimicrobial defense for the wasp larvae that parallels the 'combination prophylaxis' known from human medicine.
