Agrobacterium tumefaciens-mediated transformation (ATMT)was used for random insertional mutagenesis to identify pathogenicity genes in the hemibiotrophic fungus Colletotrichum higginsianum. A high-throughput primary infection assay on Arabidopsis thaliana seedlings allowed the rapid screening of 8,850 transformants. Forty mutants showing reproducible pathogenicity defects on Arabidopsis and Brassica plants were obtained, and their infection phenotypes were characterized microscopically. Six mutants were impaired in appressorial melanization, fifteen had reduced penetration ability, 14 induced host papillae or hypersensitive cell death, and five were affected in the transition from biotrophy to necrotrophy. Southern blot analysis showed 58
