False-colour scanning electron micrograph of the pathogenic fungus Fusarium oxysporum, which causes wilt disease in tomato and carnation plants. The micrograph shows the hyphae, or vegetative structure of the fungus in the background coloured green. The pink and organge structures, branching off from main hyphal filaments, are conidiophores or specialised spore producing bodies. The conidia, or spores, are produced from the tips of these structures and when ripe are released into the soil. One such structure that has released its conidia is visible at top right showing a jagged crown-like opening. Magnification: x2000 at 6x4.4cm size.
