Fig. 3. Bright-field and fluorescent micrographs of stolon tips from colonies of P. carnea. (A,B) A healthy stolon tip (A) from a control colony exhibits relatively little NO-related fluorescence (B). (C,D) A regressing stolon tip (C) after 60 min treatment with 5 mmol l–1 H2O2 (D) exhibits an elevated level of NO-related fluorescence. (E,F) A regressing stolon tip (E) after 60 min treatment with 0.5 mmol l–1 SNAP (F) exhibits an elevated level of NO-related fluorescence. Scale bar, 25 µm.
