A group I intron-like sequence in the nuclear small ribosomal subunit gene of the ophiostomatoid fungus Gondwanamyces proteae.
During a phylogenetic study of ophiostomatoid fungi, a group I intron-like sequence was noted in the SSU rDNA gene of Gondwanamyces proteae. Secondary structure and sequence characteristics assigned the intron to the I E class. We then examined 27 related Group I-like sequences deposited in GenBank, and as a result 15 additional and previously uncategorized I E rDNA introns were identified. This study, with other recent publications, suggests that the I E class might represent a major family of group I introns that are located within the nuclear SSU and, to some extent LSU, genes in fungi.
