Fig 3. Changes (%) of the ultrastructure of plastids induced by high light, Botrytis infection, and senescence.

Fig 3

Data in graphs (A) are means with standard errors determined by image analysis on ultra-thin cross sections of leaves according to Table 1. Changes of the area of plastid fine structures were determined by TEM and image analysis of ultra-thin sections of control plants (B), plants grown under high light conditions of 1,500 μmol m-2 s-1 (C), inoculated with Botrytis (D), and after dark induced senescence (E). Significant differences were calculated using the Mann- Whitney U test; ** and *** indicate a significance at a level of confidence of p<0.01 and p<0.001. C = chloroplasts, IS = intercellular space, M = mitochondria, N = nucleus, St = starch, V = vacuoles. Arrows = plastoglobules, Arrowheads = thylakoids. Bars = 1 μm.
