Nuclear omnipotent suppressors of premature termination codons in mitochondrial genes affect the 37S mitoribosomal subunit.

abstract：:To gain a deeper insight into the evolution of mating-type genes from filamentous ascomycetes, a comprehensive sequence analysis of PCR-amplified sequences corresponding to A- and a-specific mating-type sequences was undertaken. The study included nine homothallic (compatible) and eight heterothallic (incompatible) me...
