To investigate maturation of spermatia of Botryotinia fuckeliana, we examined micro-structural changes in spermatia in liquid culture. Three to four spherical lipid bodies were seen in the center of the cell at the start of culturing. After 3-7 days, maturing spermatia had developed large mitochondria along with extensively developed granular endoplasmic reticulum. In contrast, the lipid bodies decreased not only in number but also in size over time. The results obtained here suggest that the maturation of spermatia involves active cell metabolism using the energy supply from lipid bodies.
