Spatial distribution of microtubules in Neurospora crassa GFP in constraining meandered channels. (A) Single-plane fluorescence image of GFP-tagged microtubules. The microtubule alignment largely follows the initial direction of growth at the entry into the constraining channel. The colors represent the relative spatial density of microtubules (see color map, Right). (B) Microtubule density profiles, plotted as the fluorescence intensities along the vertical lines (1 to 3) drawn across the hyphal cross-section in A.
