challenges of the identical varieties otherwise of various types. anserina (Fig. six ) . Low-Molecular-Lbs Mitochondrial DNA (Mitochondria1Plasmids) Following the newest finding of your dos y meters plasmid regarding this new fungus Saccharonzyces cerevisiae, a rounded eukaryotic plasmid in the nucleus (select lower than), the first rounded plasmid for the mitochondria are recognized within the Podospora ansen’na [ll-131. It plasmid, that was called plDNA (otherwise an excellent-SEN DNA), is among the most several plasmids that are of a good variety of phenotype-that is, senescence. Within the juvenile societies out-of P. anserina it will be the very first intron of your own mitochondria1 gene programming to possess cytochrome oxidase subunit I (COO(Fig. 4).
During senescence this intron gets liberated and can getting remote due to the fact an autonomous, game feature [to have analysis see fourteen-16]. Due to the fact earliest description of this type out-of hereditary aspects, certain mitochondria1 plasmids was recognized in a lot of kinds.Leggi tutto
