Última Expression of the bacterial recA gene impairs genetic recombination and sporulation in a Saccharomyces cerevisiae diploid strain Genet. Mol. Biol. Morais Junior,Marcos Antonio de; Santos,José Ferreira dos; Henriques,João Antonio Pegas. The Escherichia coli RecA protein (RecAp) has been demonstrated to induce mutagenesis in yeast cells, although there is still little information on the role of the RecAp in yeast recombination events. We evaluated spontaneous and induced general recombination in vegetative and meiotic cells of the XS2316 strain of the yeast Saccharomyces cerevisiae bearing the recA gene. We found that RecAp decreased reciprocal recombination, gene conversion and intrachromosomal recombination and promoted an increase in error-prone processes in both vegetative and meiotic cells, while its negative effect on meiotic recombination blocked ascospore formation.

The aim of this study was to assess oval conidia production in mutants for the reductase nitrate gene in C. sublineolum and verify the possibility of using them as a tool to transfer the genetic material in this species. The mutants used in the present study lost the ability to form falcate conidia but all produced oval conidia. The number of nuclei by conidium was evaluated. Oval conidia were efficient in the heterokaryon formation and these heterokaryons in liquid culture medium they also produced oval conidia in abundance. Recombinants were obtained and the genetic exchanges were confirmed by the RAPD analyses. Tipo: Info:eu-repo/semantics/article Palavras-chave: Genetic recombination; Nit mutants; Parameiosis.
