Autonomous replicating sequences are DNA elements that trigger DNA replication and are widely used in the development of episomal transformation vectors for fungi. In this paper, a genomic library from the mycorrhizal fungus Gigaspora rosea was constructed in the integrative plasmid YIp5 and screened in the budding yeast Saccharomyces cerevisiae for sequences that act as ARS and trigger plasmid replication. Two genetic elements (GrARS2, GrARS6)promoted high-rates of yeast transformation. Sequence analysis of these elements shows them to be AT-rich (72-80
