TL;DR: The presence of a second pheromone gene in thea2 allele suggests that the present locus had a multiallelic ancestor and the role of these genes during mating and pathogenic development is investigated and it is speculated that they might affect mitochondrial inheritance.

Abstract: Thea mating type locus ofUstilago maydis contains the structural genes for a pheromone-based cell recognition system that governs fusion of haploid cells. The locus exists in two alleles, termeda1 anda2. We have completed the analysis of the nucleotide sequences unique toa1 anda2. Within these dissimilar regions we find two short patches of DNA sequence similarity. Interestingly, one of these segments corresponds to the transcribed region of thea1 pheromone precursor. As a result of multiple nucleotide exchanges this sequence does not code for a functional product. The existence of a second pheromone gene in thea2 allele suggests that the present locus had a multiallelic ancestor. In addition, we describe the presence of two additional genes in thea2 allele. We have investigated the role of these genes during mating and pathogenic development and speculate that they might affect mitochondrial inheritance.

Prenyl proteins in eukaryotic cells: a new type of membrane anchor
TL;DR: This work has indicated that eukaryotic cells contain proteins that are post-translationally modified by long-chain, thioether-linked prenyl groups, which appears to initiate a set of additional protein modification reactions that promote attachment of the proteins to specific membranes.
