In previous research Velicer had found that some M lipitor online . Xanthus strains constructed as social cheaters that do not behave the fruiting bodies on their own, but can take advantage of the fruiting bodies of other cells. Such a fraudsters called OC, or ‘obligate cheater ‘, had spontaneously developed in an earlier experiment. OC cells produce as many as 100 times more spores constructed as wild-type cells within fruiting bodies of both cell types, although OC far fewer spores than wild-type separate separate pure groups. But OC cheating ways have a downside. As OC cells outcompete wild-type cells in mixed groups, subsequent generations have fewer wild-type cells. Since wild-type wild-type performers in number, so do OC opportunities for making spores. Wild type strainpopulations in which OC and wild type allows each low over several cycles of development and growth crash numbers when the cheater become become widespread.
During one such competition, a spontaneously mutated descendent of OC emerged in the population that not only outcompeted both OC and wild-type cells, but also demonstrated renewed capacity for the production of fruiting bodies and spores in pure culture. Velicer name of the mutant PX and uses newly developed genome sequencing technology to identify a single point mutation , differs from the PX OC. Yu then performed experiments to show that this was a mutation, in fact, the immediate cause of the rise and success PX. However, it remained the mechanism by which this mutation fruiting body development in PX again a mystery.
