The Onion yellows phytoplasma OY-M genome is 0.86 Million bp long and contains approximately 793
predicted genes.
The sequence was released 12/09/2003 by the University of Tokyo, Japan, and was described
in Nat Genet :27-9 (2004) Oshima K, Kakizawa S, Nishigawa H, Jung HY, Wei W, et al. "Reductive evolution suggested from the complete genome sequence of a plant-pathogenic phytoplasma.

Abstract: The minimal gene set essential for life has long been sought. We report the 860-kb genome of the obligate intracellular plant pathogen phytoplasma (Candidatus Phytoplasma asteris, OY strain). The phytoplasma genome encodes even fewer metabolic functions than do mycoplasma genomes. It lacks the pentose phosphate cycle and, more unexpectedly, ATP-synthase subunits, which are thought to be essential for life. This may be the result of reductive evolution as a consequence of life as an... [Click above reference link for full abstract]
