Fig. 5

TEM of larval midgut fed inactivated yeast cells. a Normal appearance of gut of L3 fed on inactivated yeast cells (Y) sequestered in the endoperitrophic space. The PM2 (arrows) and extensive microvilli (mv) are visible. Inset shows mv and the PM2 in greater detail. b Midgut epithelial cell showing cell junctions (arrowhead) between adjacent cells, mv, and basal lamina (b). The nucleus (n) and integral nuclear membrane are also visible. c Greater detail of midgut epithelial cells with clearly distinguishable cell junction (arrowhead), mitochondria (m) and microvilli (MV). Abbreviations: PM, Type 2 peritrophic matrix
