Figure 6From: The pathway of cell dismantling during programmed cell death in lace plant (Aponogeton madagascariensis) leavesPlasma membrane intactness, demonstrated by Evans Blue staining. (A) Window stage leaf stained with Evans Blue. Note the gradient of PCD that exists, with the outermost cells being non-PCD (NPCD) stage cells and the centermost being late-PCD (LPCD) stage cells and the centermost being late-PCD stage cells (LPCD). Also note that only LPCD stage cells, with collapsed PMs, stain blue. (B) Higher magnification of a similar leaf as shown in panel A, again note that only cells with collapsed PMs possess blue staining. Scale Bars: A = 100 μm, B = 50 μm.Back to article page
