title: Characterization of the Cephalosporium acremonium ribosomal RNA genes.
abstract: To investigate the organization of the ribosomal RNA genes in Cephalosporium acremonium, we cloned the whole r X DNA repeat in pBR322 and pNEO plasmids. Both the cloned and the genomic r X DNA fragments were characterized by restriction mapping. The r X DNA repeat unit was found to be 8.0 kb long and there was no significant heterogeneity among the individual repeats.
