Andaliman (Zanthoxylum acanthopodium DC) is a native plant of North Sumatra province. Zanthoxylum member Rutaceae family widely found in northern Sumatra, Indonesia. The aim this study was to barcode Z. province, Indonesia based on cpDNA maturase K (matK). Samples were collected seven localities across six regions Phylogenetic analysis conducted using Maximum Likelihood method. results phylogen...
Symptomatic grapevine samples were collected from vineyards in Zanjan province to detect Grapevine virus A. Total RNA was extracted from symptomatic leaf samples and subjected to cDNA synthesis using random hexamer primers. Then, a DNA fragment around 800 bp including the complete coat protein (CP) gene was amplified from nine out of 57 samples by polymerase chain reaction (PCR) using specific ...
In this paper, we introduce a new phylogenetic tree algorithm that generates phylogenetic trees by repeatedly inserting species one-by-one. The incremental phylogenetic tree algorithm can work on proteins or DNA sequences. Computer experiments show that the new algorithm is better than the commonly used UPGMA and Neighbor Joining algorithms. Keywords—Data structure, Distance matrix, Phylogeneti...
A new species of Cyrtodactylus is described from the southern Western Ghats India. It distinguished all collegalensis complex in colour pattern and resembles Srilankan endemic C. yakhuna overall colouration. Phylogenetic analysis mitochondrial ND2 DNA sequences indicates that most closely related to differs them by an uncorrected pairwise genetic distance 10.5–12.9%.
Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) and phylogenetic analysis were used for molecular identification of lactic acid bacteria (LABs) isolated from Apis mellifera. Eighteen honeybee workers were collected from three different apiaries in West Azerbaijan. LABs from the gut of honeybees were isolated and cultured using routine biochemical proce...
Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selecte...
