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