Epifluorescent (left hand panels) and TEM micrographs (right hand panels) of wild-type (line 43A9) and mutant Arabidopsis leaf mitochondria.
Epifluorescent micrographs are false-coloured for GFP (green) and chlorophyll autofluorescence (red). a & b, Wild-type, arrows = mitochondria, * = chloroplast. c & d, mmt1 mutant, * = chloroplast. e & f mmt2 mutant, plain arrows = large mitochondria, arrows with circle = small mitochondria, the boxes indicate an area magnified to highlight the heterogeneity of mitochondria size within a single cell, * = chloroplast with dense mass of internal membranes. g & h bmt1 mutant, arrow = mitochondria. i & j nmt mutant, arrows indicate small mitochondria, * = chloroplast. k & l fmt mutant, arrow = large mitochondrial cluster, boxes indicate an area magnified to highlight a large cluster of mitochondria, * = chloroplast. Scale bars in epifluorescent images = 5 μm; in TEMs = 1μm, except in d where the bar = 5μm.
