[Phylogenetic classification of plant pathogenic mycoplasma].
Reductive evolution suggested from the complete genome sequence of a plant-pathogenic phytoplasma
The phytoplasma genome encodes even fewer metabolic functions than do mycoplasma genomes, and lacks the pentose phosphate cycle and ATP-synthase subunits, which are thought to be essential for life.

Phytoplasma can increase fecundity and survival of insect vectors, and may influence flight behaviour and plant host preference of their insect hosts, but generally do not negatively affect the fitness of their major insect vectors.
The family Closteroviridae revised
The mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine), and the family now comprises three genera.

It is shown that a single virulence factor, tengu-su inducer (TENGU), induces witches' broom and dwarfism and is a small secreted protein of the plant-pathogenic bacterium, phytoplasma.
'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.…

This study focused on an abundant cell-surface membrane protein of the phytoplasma named antigenic membrane protein (Amp), which is not homologous with any reported functional protein, and reported interactions between pathogens and mammalian microfilaments between a bacterial surface protein and a host microfilament in insect cells.
Transferring Cucumber Mosaic Virus-White Leaf Strain Coat Protein Gene into Cucumis melo L. and Evaluating Transgenic Plants for Protection against Infections
Flow cytometry analysis of leaf tissue revealed that a significant number of transgenic plants were tetraploid or mixoploid, whereas the commercial nontransformed cultivars were diploid, while in a study of young, germinated cotyledons, a mixture of diploids, tetraPloid, and octoploid cells were found at the shoot regeneration sites.
Complete nucleotide sequence of wheat yellow mosaic bymovirus genomic RNAs
The sequence data indicate that WYMV and WSSMV are not strains of the same virus, which has long been suggested, but are distinct virus species within the genus Bymovirus of the family Potyviridae.
Lectin-Mediated Resistance Impairs Plant Virus Infection at the Cellular Level[C][W][OA]
Analysis of resistance of certain Arabidopsis thaliana ecotypes to a potexvirus to show the existence of lectin genes that show a variety of levels of virus resistance, their targets, and their properties, which are distinct from those of known R genes, suggests the generality of Lectin-mediated resistance in plant innate immunity.
