Cellulose synthase and other members of the family 2 glycosyltransferases are ubiquitous in all kingdoms of life. To date, no attempt has been made to construct a phylogeny that positions cellulose synthases in relation to other members of this family or to elucidate relationships within the cellulose synthase group. In this study, a sequence from the unicellular, marine cyanobacterium Synechoc...
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 ...
Phylogenetic relationships were investigated among North American species of Laetiporus, Leptoporus, Phaeolus, Pycnoporellus and Wolfiporia using ITS, nuclear large subunit and mitochondrial small subunit rDNA sequences. Members of these genera have poroid hymenophores, simple septate hyphae and cause brown rots in a variety of substrates. Analyses indicate that Laetiporus and Wolfiporia are no...
The sequence of the genomic region that contains the Adh and Adhr genes of Drosophila funebris was used to demonstrate that both genes are present in species of the funebris group. The sequence of this genomic region reveals a 2.9-kb tandem duplication which encompasses 1.6 kb of the 5' flanking region, the entire Adh gene, and two thirds of the first exon of the Adhr gene in D. funebris. This ...
Aphelinus mali (Haldeman) (Hymenoptera: Aphelinidae) is an effective natural enemy used in China to control the woolly apple aphid (Eriosoma lanigerum [Hausmann]) (WAA). Population of A. mali in China falls into two distinct genetic clades (Shandong clades and Liaoning clades). In the present results, the developmental threshold temperature of the Shandong clade (9.82 ± 1.44 °C) was lower than ...
Species distributed across vast continental areas and across major biomes provide unique model systems for studies of biotic diversification, yet also constitute daunting financial, logistic and political challenges for data collection across such regions. The tree frog Dendropsophus minutus (Anura: Hylidae) is a nominal species, continentally distributed in South America, that may represent a ...
In the present study, phylogenetic relationships of European and Far Eastern representatives of the genus Aspidogaster Baer, 1827 were analysed: A. conchicola Baer, 1827, A. limacoides Diesing, 1834, A. ijimai Kawamura, 1915 and A. chongqingensis Wei, Huang & Dai, 2001. Based on ITS1-5.8S-ITS2 rDNA sequence data, an obvious differentiation was seen between specimens of A. limacoides s ensu stri...
We sequenced to near completion the entire mtDNA of 28 Sardinian goats, selected to represent the widest possible diversity of the most widespread mitochondrial evolutionary lineage, haplogroup (Hg) A. These specimens were reporters of the diversity in the island but also elsewhere, as inferred from their affiliation to each of 11 clades defined by D-loop variation. Two reference sequences comp...
