Obiettivo del progetto (Objective)
'By detailed evolutionary comparisons among multiple sequenced yeast genomes, we have identified several unusual regions where our preliminary evidence suggests that previously unknown molecular biology phenomena, involving rearrangement of genomic DNA, are occurring. I now propose to use a combination of dry-lab and wet-lab experimental approaches to characterize these regions and phenomena further. One region is a 24-kb section of chromosome XIV that appears to undergo recurrent 'flip/flop' inversion between two isomers at a fairly high rate in five species as diverse as Saccharomyces cerevisiae and Naumovia castellii, leading to a 1:1 ratio of the two isomers in each species. We hypothesize that this region is the site of a programmed DNA rearrangement analogous to mating-type switching. We have also identified two new genes related to the mating-type switching endonuclease HO, but different from it, that are potentially involved in rearrangement processes though not necessarily the inversion described above. We will determine the sites of action of these endonucleases. Separately, we have found evidence for a process of recurrent deletion of DNA from regions flanking the mating-type (MAT) locus in all yeast species that are descended from the whole-genome duplication (WGD) event, causing continual transpositions of genes from beside MAT to other locations in the genome. In related computational work, we propose to investigate an hypothesis that evolutionary loss of the MATa2 transcriptional activator may have been the cause of the WGD event.'
