Short term photoheterotrophic growth of Lemna minor in the presence of 100 micrograms per milliliter (440 micromolar) cytidine deoxyriboside bleaches the fronds in the absence of effect upon growth rate (Frick 1978 Plant Physiol 61: 989-992). Serial sections of mesophyll cells of green and bleached fronds were compared in the light microscope. The number of plastids in cells of comparable size was reduced during bleaching by more than 50%. The total and average plastid profile area per section in the series was reduced on the order of 70%, and the summed plastid profile area over the entire cell was reduced about 90%. Thus, cytidine deoxyri-boside-bleached mesophyll cells contained fewer identifiable plastids (50%) of smaller volume (10-30%) than the green control cells.
