Interaction of PH3 and TTG2 with WD40 Proteins.
Yeast strains expressing the indicated GAL4AD and GAL4BD fusions were grown on dropout media lacking leucine (−L), tryptophan (−T), histidine (−H), and/or adenine (−A). Activation of the GAL4-regulated HIS and ADE reporter genes is seen as growth on –LTH and –LTHA media and of the lacZ gene as a blue staining after overlaying the cells with X-Gal.
