Green: medial confocal optical sections through apical initial cells of protonemal filaments (A and B) or rhizoids (A) displaying estradiol-titratable expression at minimal detectable level of the indicated full-length (A) or truncated (B) YFP fusion proteins, or of free YFP. Distribution patterns were highly reproducible (n >= 20). Grayscale: transmitted light reference images (Nomarski). Scale bars, 25 μm (protonemal cells) and 50 μm (rhizoid cells).
