title: A chromosome map of the Flavescence doree phytoplasma.
abstract: The Flavescence dorée phytoplasma (FD-P), a non-cultivable, plant-pathogenic bacterium of the class Mollicutes, is the causal agent of a quarantine disease affecting vineyards of southern Europe, mainly in southern France and northern Italy. To investigate FD-P diversity and phytoplasma genetic determinants governing the FD-P life cycle, a genome project has been initiated. A physical map of the chromosome of FD-P strain FD92, purified from infected broad beans, was constructed by performing restriction digests of the chromosome and resolving the fragments by PFGE. Single and double digestions of the chromosome with the enzymes SalI, BssHII, MluI and EagI were performed and used to map 13 restriction sites on the FD-P chromosome. The size of the chromosome was calculated to be 671 kbp. Southern blot analyses using cloned phytoplasma probes were carried out to assist in the arrangement of contiguous restriction fragments and to map eight genetic loci, including the two rRNA operons, the tuf, uvrB-degV and secY-map (FD9) genes, the FD2 marker and two orphan sequences (FDDH29 and FDSH05) isolated through subtractive suppression hybridization.
