Expression of GFP in <i>G. lucidum</i>.

<p>A GFP-expressing <i>G. lucidum</i> transformant was cultivated on CYM agar medium at 28°C and examined microscopically. Fluorescence of wild-type <i>G. lucidum</i> (A and C) and the GFP transformant (B and D) was examined. Mycelia were removed from actively growing colonies, suspended in sterile water, and viewed microscopically. Samples shown in panels A and B were examined using bright-field microscopy, and samples in panels C and D were viewed using blue-field microscopy. Bars = 50 µm.
