FIG. 4.

GAL1 memory does not require nuclear pore localization or H2A.Z. Schematics at the top depict regimens of growth in different carbon sources. Raf, 2% raffinose; Gal, 2% galactose; Glc, 2% glucose. (a) RT-PCR analysis of GAL10 induction and reinduction in nup2Δ cells following long-term glucose repression (12 h). Long-term memory does not require Nup2p. Data represent data from three independent experiments. (b) Short-term GAL1 memory is unaffected in nup2Δ (left) and sac3Δ (right) mutants. (c) Northern analysis of wild-type (left) and htz1Δ (right) strains showing rapid GAL1 reinduction following short-term glucose repression (1 h). Data are representative of data from three independent experiments.
