Opis:: The protein encoded by the IRR1/SCC3 gene is an element of the cohesin complex of Saccharomyces cerevisiae, responsible for establishing and maintaining sister chromatid cohesion during mitotic cell division. We noticed previously that lowering the level of expression of IRR1/SCC3 affects colony formation on solid support. Here we describe two dosage suppressors (IST2, NOG2) overcoming the inability to form colonies of an Irr1p-deficient strain. Ist2 is probably involved in osmotolerance, Nog2p is a putative GTPase required for 60S ribosomal subunit maturation, but may also participate in mRNA splicing.

Tytuł:: Ultrastructure and SSU rDNA Phylogeny of Paraphysomonas vestita (Stokes) De Saedeleer Isolated from Laguna de Bay, Philippines

Tematy:: Paraphysomonas vestita, chrysophyte, protist, ultrastructure, small subunit ribosomal RNA gene, Philippines
Opis:: Paraphysomonas vestita is a unicellular, colorless, silica-scaled chrysophyte that plays an important ecological role in freshwater microbial communities as a consumer of prokaryotic and eukaryotic prey. There is little biogeographical information for this minute protist despite its significant role in aquatic food webs. In addition, the phylogenetic relationship of P. vestita to other taxa is unclear as P. vestita may be polyphyletic or a cryptic species complex. In this study, a clonal isolate from a freshwater sample of Laguna de Bay, Philippines was subjected to morphological study by electron microscopy and its small subunit ribosomal RNA (SSU rRNA) gene was sequenced. Morphological studies showed that the isolate possesses two unequal flagella emerging from the anterior part of the cell. Negative staining revealed the structure of the scales which consist of a baseplate with slightly thickened rim. The narrowing spine arises from the center of the baseplate. These results agree with previously studied isolates of P. vestita. The 18S rRNA gene sequence of the isolate had a very high similarity (99%) to P. vestita strain PV10. Phylogenetic analysis also showed that the isolate clustered with other Paraphysomonas sequences with high bootstrap support. Phylogenetic studies confirmed that P. vestita may be polyphyletic. No studies on the ultrastructure and phylogeny of a silica-scaled chrysophyte isolated in the Philippines have been reported so far. Results from this study may contribute to further ultrastructural and phylogenetic studies on aquatic flagellates and specifically to a revision of this potentially polyphyletic species.

Tytuł:: Morphology and Molecular Phylogeny of Pseudouroleptus jejuensis nov. spec., a New Soil Ciliate (Ciliophora, Spirotrichea) from South Korea

Tematy:: Pseudouroleptus jejuensis, soil ciliate, morphology, small subunit ribosomal RNA gene, oxytrichid, South Korea
Opis:: A new soil ciliate, Pseudouroleptus jejuensis, was discovered from Jeju Island, South Korea and described based on live observation, protargol impregnation, and SSU rRNA gene sequence analyses. Pseudouroleptus jejuensis differs from other congeneric species mainly by number of dorsal kineties (5 vs. 4). Based on our observation of late dividers, we confirm that the dorsal kinety anlage 3 forms 3 kineties (i.e., dorsal kineties 3–5), and the dorsal kinety anlagen 1–3 form 3–5/1–2/0 caudal cirri, respectively. Our gene trees support the assignment of this new species in Pseudouroleptus to full supporting values.

Opis:: The ribosome is a macromolecular assembly that is responsible for protein biosynthesis in all organisms. It is composed of two-subunit, ribonucleoprotein particles that translate the genetic material into an encoded polypeptides. The small subunit is the site of codon-anticodon interaction between the messenger RNA (mRNA) and transfer RNA (tRNA) substrates, and the large subunit catalyses peptide bond formation. The peptidyltransferase activity is fulfilled by 23S rRNA, which means that ribosome is a ribozyme. 5S rRNA is a conserved component of the large ribosomal subunit that is thought to enhance protein synthesis by stabilizing ribosome structure. This paper shortly summarises new results obtained on the structure and function of 5S rRNA.
