A comparison of the nucleotide sequence of the cerato-ulmin gene and the rDNA ITS between aggressive and non-aggressive isolates of Ophiostoma ulmi sensu lato, the causal agent of Dutch elm disease.

Abstract excerpt

Little genetic information exists comparing aggressive and non-aggressive isolates of the causal agent of Dutch elm disease, Ophiostoma ulmi. Two genetic elements were compared between the subgroups. The ceratoulmin cu gene product has been associated with disease symptoms. Nucleotide-sequence analysis of cu and the internal transcribed spacer (ITS) region of the rDNA were made from three aggressive and three...
