Tema(s): Recursos en línea: Resumen: A screen for insertional mutants of Colletrichum lindemuthianum, the causative agent of common bean anthracnose, led to the identification of a non-pathogenic, lightly colored transformant. This mutant is unable to induce disease symptoms on intact or wounded primary leaves of seedlings and plantlets of Phaseolus vulgaris. In vitro, it exhibits normal vegetative growth, sporulation and conidial germination, but the cultures remain beige instead of becoming black. Microscopic examination revealed that this mutant forms fewer appressoria than the wild-type strain, and these are misshapen and poorly melanized. Molecular analyses indicated that the mutagenic plasmid had targeted clap1, a gene encoding a putative copper-transporting ATPase sharing 35
