Archaea have been isolated from the human colon, vagina, and oral cavity, but have not been established as causes of human disease. In this study, we reveal a relationship between the severity of periodontal disease and the relative abundance of archaeal small subunit ribosomal RNA genes (SSU rDNA) in the subgingival crevice by using quantitative PCR. Furthermore, the relative abundance of arch...

Phylogenetic relationships of termitophilic fungi were estimated with Bayesian as well as other phylogenetic methods from partial sequences of the nuclear encoded large subunit ribosomal DNA (nLSU-rDNA) and the mitochondrial encoded small subunit ribosomal DNA (mtSSU-rDNA). Sequences were obtained from basidiomes covering the morphological, taxonomical, and geographical span of termitophilic mu...

Chromatin Assembly Factor 1 (CAF-1) is an evolutionary conserved heterotrimeric chaperone complex that facilitates the incorporation of histones H3 and H4 onto newly synthesized DNA. We demonstrate here that the mutant deficient for the large subunit of the complex, fas1-4, and in minor extent, the mutant deficient for the middle subunit, fas2-1, display chromosome abnormalities throughout Arab...

In the budding yeast of Saccharomyces cerevisiae the tandem repeated of rDNA genes are located onchromosome XII, which is in the nucleolus. There are different types of proteins in the nucleoluskeleton,silencing proteins have got important role in nucleolus.It is shown that meiotic recombination between nonsister chromatids in the rDNA genes are stronglysuppressed, and s...

Common and dwarf bunt of wheat are recognized as being caused by three closely related species, Tilletia caries and T. laevis as common bunt, and T. controversa as dwarf bunt. The morphological characteristics of two species including T. controversa and T. caries were studied from wheat grown in two provinces of Iran, Lorestan and Chaharmahal–o-Bakhtiari duri...

Fungi have unique properties and are used in many areas of agriculture industry because they can produce different enzymes. This study aims to the fungal diversity peat soil from Pontian Johor, Malaysia. The isolates were described on culture media a new medium called EVA identified using phenotypical characteristics molecular D1/D2 domain 28S large subunit ribosomal RNA (28S rRNA) ITS (ITS1-IT...

background: dirofilaria immitis and dirofilaria repens are the most common species of filarial nematodes described in the dogs. a single-step multiplex pcr was applied to detect and differentiate simultaneously and unequivocally d. im­mitis and d. repens on dna extracted from canine peripheral blood and besides to detect the seroprevalance of d. immitis by elisa in elazig province, turkey. a pc...

The morphology of four trachelocercid ciliates, Paratrachelocerca typica gen. nov., spec. Trachelolophos monocaryon ( Dragesco, 1965 ) comb. nov. (original combination: Tracheloraphis ), katzae and colubis Kahl, 1933 Xu et al., 2011 were studied in live protargol-stained specimens. All samples isolated from the intertidal zone sandy beaches at Qingdao, China. new genus can be distinguished othe...
