In other organisms, such procedures have depended for their success on the identification of important regulatory sequences and novel genetic elements, providing a means to develop appropriate vectors for the cloning, in vitro manipulation, reintroduction, and controlled expression of important genes. 2004 Jan 21;325:79-87. doi: 10.1016/j.gene.2003.09.041. Here, we report a remarkable exception in the slime mold Physarum polycephalum. Currently a project targeting the whole genome of this organism is underway at the Genome Sequencing Center of Washington University [ 11 ]. The slime mold's genome is comprised of 188 million nucleotides, encoding 34 000 genes, which is over 50 percent more than the human genome has. Evidence for a homolog of the yeast cell cycle regulatory gene product of cdc2+ in Physarum polycephalum. Prior, C. P., Cantor, C. R., Johnson, E. M., Littau, V. C., and Allfrey, V.

The Physarum polycephalum genome reveals extensive use of prokaryotic two-component and metazoan-type tyrosine kinase signaling. RNAs transcribed from the mitochondrial genome of Physarum polycephalum are heavily edited. Unable to display preview. Please enable it to take advantage of the complete set of features! The substantially larger genome of Physarum polycephalum (estimated to be ∼300 Mb; Mohberg and Rusch 1971) could potentially harbor a substantially higher number of genes, but thus far there is no indication this is so (Baekmann and Sauer 1982). Comparison of insertional RNA editing in Myxomycetes. 1822: taxonomy/phylogenetic: Index Fungorum: Physarum polycephalum Schwein.  |  Insertional editing in mitochondria of Physarum. Physarum polycephalum is a well-studied microbial eukaryote with unique experimental attributes relative to other experimental model organisms. Despite the basic aspect of Physarum, this can be shapeless yellow protoplasm, flagellate unicellular, and fruit bodies; the life cycle suggests a sophisticated genome with a complex organization (Aldrich and Daniel, 1982, Sauer, 1982) ()..
