Fluorescent protein gene induction by CUP1 and ADH1 promoter.

<p>(A) Yeast cells (YS129 strain) transformed with pCM25 (<i>CUP1</i>-yEVenus-Cln2 -NLS) were cultured in the presence or absence of copper nitrate for 1 hr (middle panels) and 6 hrs (bottom panels). Cells with no copper nitrate are also shown in the upper panel. (B) Yeast cells (YS129) with pDHM57 (<i>ADH1</i>-yEVenus-Cln2 -NLS). (C) Yeast cells (YS129) with pRN1 (<i>ADH1</i>-yEVenus-NLS). Note that the fluorescence images in (B) and (C) were captured with the same exposure time. DIC: differential interference contrast; YFP: YFP filter channel for the detection of Venus fluorescence. .
