Wild-type filaments (A) grown in complete medium and (B) in medium lacking nitrogen to induce heterocysts (arrowheads) are shown below. (C) Overexpression of the patS gene prevented heterocyst formation, and (D) deletion of the patS gene resulted in additional heterocysts with an abnormal pattern. Brackets indicate chains of contiguous heterocysts. Scale bars, 10 µm.
