Western X-disease (WX) phytoplasma is an uncultivable, intracellular pathogen of plants and insects with an AT-rich genome of 670 kb. As part of the genome sequencing project of WX phytoplasma, we have cloned approximately 50% of its genome into the pcosRW2 cosmid vector using DNA purified from pulsed-field gels. One of the cosmid clones with an insert of 24.6 kb was sequenced, which along with the cosmid end sequences, represents 60 kb of unique sequence from the WX phytoplasma genome. The putative genes identified in this sequence represent a wide variety of functions and many had not been previously identified in a phytoplasma.
