Challenges of phylogenetic analyses of aDNA sequences.

One of the crucial steps of authentication of aDNA sequences is phylogenetic consistency. Amplified sequences should fit into the phylogenetic framework of their supposed origin. An inherent property of aDNA sequences however, is their short sequence length. Additionally, genes for aDNA studies are often chosen by their preservation potential rather than by phylogenetically informative content....

Rapid determination of 16S ribosomal RNA sequences for phylogenetic analyses.

Although the applicability of small subunit ribosomal RNA (16S rRNA) sequences for bacterial classification is now well accepted, the general use of these molecules has been hindered by the technical difficulty of obtaining their sequences. A protocol is described for rapidly generating large blocks of 16S rRNA sequence data without isolation of the 16S rRNA or cloning of its gene. The 16S rRNA...

Coniothyrium zuluense causes a serious canker disease of Eucalyptus in various parts of the world. Very little is known regarding the taxonomy of this asexual fungus, which was provided with a name based solely on morphological characteristics. In this study we consider the phylogenetic position of C. zuluense using DNA-based techniques. Distance analysis using 18S and ITS regions revealed exte...

Sequences and Phylogenetic Analysis of Envelope (E) Gene of Iranian Infectious Bronchitis Virus Isolates in Iran

Background and Aims: Infectious bronchitis virus (IBV) is the etiological agent of infectious bronchitis (IB), which is an acute and highly contagious disease of the respiratory and sometimes the urogenital tracts of chickens. In Iran, the disease has been identified in chicken flocks with serological and virus isolation methods. Gene 3c (E) encode envelop (small membrane) protein. For envelope...

Fasciola gigantica of Ruminants: The phylogenetic analysis based on COX1 sequences

BACKGROUND: Fasciola species are parasitic trematode with world wide distribution that infects wild and domesticated herbivores, particularly ruminants. The aim of the present study was to investigate the intra species variations of F. gigantica, from goats and buffalos isolates in two common geographic climates of Iran. METHODS: Fasciola species were collected from goat, buffalo, sheep, and ca...
