mRNA is sequestered and turned over in cytoplasmic processing bodies (PBs), which are induced by various cellular stresses. Unexpectedly, in Saccharomyces cerevisiae, mutants of the small GTPase Arf1 and various secretory pathway mutants induced a significant increase in PB number, compared with PB induction by starvation or oxidative stress.

The roles of inversion and crossover recombination in determining the spacing between two functionally linked genes on an individual strand of DNA and the resulting genetic organization throughout the population is not well understood. We employ a computer simulation to look at the spacing between functionally linked genes after many generations of a(More)
