Transmission electron microscopy (TEM) images of the tissues with structural changes during seed abortion. The original (a, c, e, g, i, and k) and zoomed-in (b, d, f, h,j, and l) TEM images are shown for different stages, namely 5DAF (a-b), 10DAF (c-d), 15DAF (e-f), 20DAF (g-h), 25DAF (i-j), and 30DAF (k-l). Red frames in a, c, e, g, i, and k indicate zoomed-in regions in these images. N, Nu, M, V, Chl, CW, RER, SG, LD, Go, P, and Pb indicate nucleus, micronucleus, mitochondrion, vacuole, chloroplast, cell wall, rough endoplasmic reticulum, starch granule, lipid droplet, Golgi complex, proteosomes, and protein body respectively
