Plasmids containing the nontranscribed central and terminal, but not the coding, regions of the extrachromosomal ribosomal deoxyribonucleic acid (rDNA) of Tetrahymena thermophila are capable of autonomous replication in Saccharomyces cerevisiae. These plasmids transform S. cerevisiae at high frequency; transformants are unstable in the absence of selection, and plasmids identical to those used for transformation were isolated from the transformed yeast cells. One plasmid contains a 1.85-kilobase Tetrahymena DNA fragment which includes the origin of bidirectional replication of the extrachromosomal rDNA. The other region of Tetrahymena rDNA allowing autonomous replication of plasmids in S. cerevisiae is a 650-base pair, adenine plus thymine-rich segment from the rDNA terminus. Neither of these Tetrahymena fragments shares obvious sequence homology with the origin of replication of the S. cerevisiae 2-microns circle plasmid or with ars1, an S. cerevisiae chromosomal replicator.

Abstract Objective The objective of the research presented here was to determine whether autonomous replication sequences (ARS) discovered in the eccDNA replicon of glyphosate resistant Amaranthus palmeri enable self-replication in a yeast system. Results Sequence analysis of the eccDNA replicon revealed a region of sharp changes in A + T/G + C content with characteristic bending indicative of an autonomous replication sequence. Further sequence analysis revealed an extended autonomous replication sequence (EACS) in close proximity to multiple DNA unwinding element (DUE) sequences. This region of the eccDNA replicon enabled autonomous replication of an ARS-less yeast plasmid.

Abstract Objective: The objective of the research presented here was to determine whether autonomous replication sequences (ARS) discovered in the eccDNA replicon of glyphosate resistant Amaranthus palmeri enable self-replication in a yeast system. Results: Sequence analysis of the eccDNA replicon revealed a region of sharp changes in A+T/G+C content with characteristic bending indicative of an autonomous replication sequence. Further sequence analysis revealed an extended autonomous replication sequence (EACS) in close proximity to multiple DNA unwinding element (DUE) sequences. This region of the eccDNA replicon enabled autonomous replication of an ARS-less yeast plasmid.
