Abstract excerpt
Starvation and cell density regulate the developmental expression of Myxococcus xanthus gene 4521. Three classes of mutants allow expression of this developmental gene during growth on nutrient agar, such that colonies of strains containing a Tn5 lac Omega4521 fusion are Lac(+). One class of these mutants inactivates SasN, a negative regulator of 4521 expression; another class activates SasS, a sensor...
