Figure 10From: Aberrant stalk development and breakdown of tip dominance in Dictyosteliumcell lines with RNAi-silenced expression of calcineurin BLongitudinal sections of stalks analyzed by electron microscopy. Wild type stalk cells (A, bright cells) are larger than 01–5 mutant stalk cells (B). Note that some of the mutant stalk cells appear to be not vacuolated (arrow). The size of spore cells (S) from wild type and mutant 01–5 (dark or grey cells outside the stalk) are similar.Back to article page
