We describe a set of replicative, integrative and single-stranded shuttle vectors constructed from the pUC19 plasmid that we use routinely in our experiments. They bear a yeast selectable marker: URA3, TRP1 or LEU2. Replicative vectors carrying different yeast replication origins have been constructed in order to have plasmids based on the same construction with a high or low copy number per cell and with different mitotic stabilities. All the vectors are small in size, provide a high yield in Escherichia coli and efficiently transform Saccharomyces cerevisiae. These plasmids have many of the unique sites of the pUC19 multicloning region and many of them allow for the screening of plasmids with an insert by alpha-complementation. The nucleotide sequence of each of them is completely known.
