Several phytoplasmas, wall-less phloem limited plant pathogenic bacteria, have been shown to contain extrachromosomal DNA (EcDNA) molecules encoding a replication associated protein (Rep) similar to that of geminiviruses, a major group of single stranded (ss) DNA plant viruses. On the basis of that observation and of structural similarities between the(More)
Sequence analysis of five of the six endopolygalacturonase-encoding genes (Bcpg1, Bcpg2, Bcpg3, Bcpg4, Bcpg5) from 32 strains of Botrytis cinerea showed marked gene to gene differences in the amount of among-strains diversity. Bcpg4 was almost invariable in all strains; Bcpg3 and Bcpg5 showed a moderate variability, similar to that of(More)
Notwithstanding the availability of several different real time PCR protocols for “Candidatus Phytoplasma mali”, it is still unclear how informative is the estimation of the concentration of phytoplasma cells in the leaves of apple proliferation infected trees, and how the reliability of the estimations may be affected by an erratic and uneven distribution(More)
