Scanning electron microscopy of B. cinerea conidia. A: Overview showing the jagged spore surface (scale bar: 1 μm). B, C: Higher magnifications, showing irregular jags of wild type (B) and triple mutant (C) spores. D: After treatment of wild type conidia with chloroform, the jags appeared abraded. E: Treatment of wild type conidia with hexane does not cause obvious changes in surface topography. F, G: Repeated washing with water caused minor abrasions of the spiny surface of wild type (F) and triple mutant (G) conidia. Scale bar for higher magnifications in B-G: 250 nm.
