[Genetic control of purine biosynthesis in the yeast Pichia methanolica. "Roman's effect" in red adenine-dependent pur6 and pur7 mutants].

Genetika - 1 Oct 1997

Dutova T A, Tolstorukov I I

Abstract excerpt

Most ade1 and ade2 mutants of the yeast Pichia methanolica generate white and pink secondary colonies (SCs) on the surface of red colonies in complete medium. The formation of SCs was shown to be caused by "Roman's effect" described in Saccharomyces cerevisiae. This effect is known to result from the preferential growth in a colony of spontaneous mutations for genes controlling the first five steps of purine...
