Analysis of genomic sequences encoding a sex pheromone from theClosterium peracerosum-strigosum-littorale complex

Genes for 19-kDa and 42-kDa subunits of protoplast-release-inducing protein (PR-IP) were cloned from theClosterium peracerosum-strigosum-littorale complex mt^sup +^ cells. Genomic sequences and transcriptional initiation sites for both genes were determined. Sequence data revealed that typical TATA boxes are located immediately upstream of both transcriptional initiation sites. Several similar sequences were observed at nearly the same location in the promoters of both genes. Based on these data, we propose some possible hypotheses regulating the expression of the PR-IP subunit genes.[PUBLICATION ABSTRACT]
