title: Presence of Ty1-copia group retrotransposon sequences in the potato late blight pathogen Phytophthora infestans.
abstract: Multiple copies of retrotransposon reverse transcriptase coding sequences were identified in Phytophthora infestans by polymerase chain reaction (PCR) amplification using degenerate primers. The P. infestans sequences belong to the Ty1-copia superfamily, and putative elements from different P. infestans isolates show restriction site polymorphisms. Some contain complete open reading frames while others do not, indicating the presence of potentially active as well as inactive elements.
