Molecular phylogeny of three desert truffles from Iran based on ribosomal genome
Authors
Abstract:
The ITS region including the 5.8S gene of rDNA of three desert truffle species were amplified using ITS4 and ITS1 primers. The ITS sequences were compared to those of other related authentic sequences obtained from GenBank. Among 12 specimens studied, seven isolates corresponded to Terfezia claveryi reported by other authors. Iranian T. claveryi specimens had an average similarity of 99.4% (range 98.7–100%) among themselves, while all T. claveryi sequences analyzed had an average of 95.2% (range 87.2–100%) similarity. Four specimens corresponded to Trimania pinoyi, being a sister taxon to Tirmania nivea, of whichonly one specimen could be studied. Iranian T.pinoyi specimenshad an average of 99.9% similarity (range 99.8–100%) among themselves, and 97.2% (range 93.1– 100%) between all T. pinoyi sequences compared.

hosts and distribution of desert truffles in iran, based on morphological and molecular criteria
terfezia, picoa and tirmania, so called desert truffles, are mycorrhizal fungi mostly endemic to arid and semi-arid areas of the mediterranean region, where they are associated with helianthemum and carexspecies. the aim of this work was to study the identification, molecular analysis, distribution and hosts of these pezizalean hypogeous fungi in iran. among the specimens, terfezia claveryi, ti...

The internal transcribed spacer regions of nuclear ribosomal DNA are widely used to infer phylogenetic relationships in plants. In this study, it was obtained the ITS sequences from 24 samples of Araceae in Iran, representing 3 genera: Arum L., Biarum Schott. and Eminium (Blume) Schott. Phylogenetic analyses were conducted by Bayesian inference and maximum Parsimony methods. Cladistic analysis ...

Abstract: Background: Hemiscorpius lepturus is a medically important scorpion found along the Iranian borders, especially near to Khuzestan Province in the south-west of Iran. This is the only non-buthid scorpion which is potentially lethal in southern Iran and is responsible for severe dermonecrotic scorpionism. OBJECTIVES: In this study, DNA fragment of the mitochondrial cytochrome c oxidase ...

15 صفحه اولArchaeal phylogeny based on ribosomal proteins.
Until recently, phylogenetic analyses of Archaea have mainly been based on ribosomal RNA (rRNA) sequence comparisons, leading to the distinction of the two major archaeal phyla: the Euryarchaeota and the Crenarchaeota. Here, thanks to the recent sequencing of several archaeal genomes, we have constructed a phylogeny based on the fusion of the sequences of the 53 ribosomal proteins present in mo...
