Fig. 3

Tomato and tobacco anthers at stage 9–11 showing the degeneration process of the tapetum. Transmission electron micrographs (TEMs) of tobacco (a) or tomato (b) anthers at anther developmental stage 9–11. Arrowheads point at intact Golgi apparatus. Arrows point at the plasma membrane of the tapetal cells. Asterisks highlight mitochondria. Msp, microspores; N, nucleus; T, tapetum; V, vacuoles. Bars = 5 μm for overall images, i.e. the top panel images in (ab); = 2 μm for close-up images, i.e. the bottom panel images in (ab)
