Abstract excerpt
Lost traits can reevolve, but the probability of trait reversion depends partly on a trait's genetic complexity. Myxobacterial fruiting body development is a complex trait controlled by the small RNA (sRNA) Pxr, which blocks development under conditions of nutrient abundance. In developmentally proficient strains of Myxococcus xanthus, starvation relaxes the inhibition by Pxr, thereby allowing development to...
