provides direct evidence that this arthropod is a competent vector (4). We report the first identification and characterization of an HGE-like agent in a blacklegged tick collected in a tick-endemic area of Canada (6). Sixty male and 60 female I. scapularis were collected from five white-tailed deer shot on Long Point Peninsula, Ontario, during November 1999. Live ticks were cut longitudinally ...

This study aimed to compare the occurrence and level of Bacillus cereus sensu stricto (B. cereus) in chili, previously isolated white pepper from traditional supermarkets around Bogor, determine phylogenetic relationship between obtained isolates based on their 16S rDNA gene, potential toxicity ces nheA genes using Polymerase Chain Reaction. The highest presumptive B. samples was 5.95×105 2.6×1...

Microbial activity in spent nuclear fuel pools which contain ultrapure and radioactive water has been previously observed. The aim of the present research was to isolate and identify the microorganisms attached to the nuclear pool wall of a Spanish nuclear power plant. Amplification of 16S rDNA fragments from the culturable microorganisms by PCR using universal primers for the domain 'Bacteria'...

A macrofungi species, Cortinarius bulliardii is collected from Tokat city province during field trips in 2019. It has a smooth, finely light fibrous, brownish-red pileus, whitish to lilac-brownish flesh, broadly ellipsoidal spores, brown when young, then dark lamellae with age. In addition morphological analysis, molecular sequence data based on the ITS and LSU rDNA gene regions indicated that ...

A circular plasmid containing a complete Tetrahymena thermophila rRNA gene (rDNA), with a tandem repeat of a 1.9-kilobase-pair segment encompassing the replication origin and the rRNA promoter, and a polylinker in the 3' nontranscribed spacer, was used to transform T. thermophila by microinjection. Most (20/21) stable transformants contained only recombinant linear palindromic rDNA molecules ca...

The target of rapamycin (TOR) kinase is an evolutionarily conserved key regulator of eukaryotic cell growth and proliferation. Recently, it has been reported that inhibition of TOR signaling pathway can delay aging and extend lifespan in several eukaryotic organisms, but how lifespan extension is mediated by inhibition of TOR signaling is poorly understood. Here we report that rapamycin treatme...

Although recombinant adeno-associated virus (rAAV) vectors are proving to be efficacious in clinical trials, the episomal character of the delivered transgene restricts their effectiveness to use in quiescent tissues, and may not provide lifelong expression. In contrast, integrating vectors enhance the risk of insertional mutagenesis. In an attempt to overcome both of these limitations, we crea...

Ribosomal RNA (rRNA) is transcribed from the ribosomal DNA (rDNA) genes by RNA polymerase I (Pol I). Despite being responsible for the majority of transcription in growing cells, Pol I regulation is poorly understood compared to Pol II. To gain new insights into rDNA transcriptional regulation, we developed a genetic assay in Saccharomyces cerevisiae that detects alterations in transcription fr...

The movement of nuclear DNA from one vascular plant species to another in the absence of fertilization is thought to be rare. Here, nonnative rRNA gene [ribosomal DNA (rDNA)] copies were identified in a set of 16 diploid barley (Hordeum) species; their origin was traceable via their internal transcribed spacer (ITS) sequence to five distinct Panicoideae genera, a lineage that split from the Poo...
