Abstract
Two morphologically distinct strains, 63–76 and 63H1, were isolated from a protoplast and a hyphal tip of the parentalSclerotium rolfsii strain S-63, respectively. Strains 63–76 and 63H1 showed reduced mycelial growth and lacked clamp connections on hyphae. The two strains also differed from each other and from their parent in RAPD patterns generated by several primers, suggesting that 63–76 and 63H1 were homokaryons isolated from the hetereokaryon S-63. Whereas the parent S-63 belonged to ITS-RFLP group 1, RFLP patterns of internal transcribed spacer (ITS) regions of rDNA of 63–76 and 63H1 were similar to those of ITS-RFLP groups 5 and 3, respectively. The sequence similarity of ITS regions were more than 99% between 63–76 and group 5 strains, 100% between 63H1 and the group 3 strain, and 96.3% between 63–76 and 63H1. Direct sequencing failed in the parental strain S-63. S-63 was considered to contain ITS types of groups 5 and 3.
