In addition to lethal minute colony mutations which correspond to loss of mitochondrial DNA, acriflavin induces in Chlamydomonas reinhardtii a low percentage of cells that grow in the light but do not divide under heterotrophic conditions. Two such obligate photoautotrophic mutants were shown to lack the cyanide-sensitive cytochrome pathway of the respiration and to have a reduced cytochrome c ...

Whiteflies are economically important plant pests that cause damage to crops worldwide. This study aimed update the status of whiteflies in Jordan by combining classical morphological identification and DNA markers using mitochondrial cytochrome oxidase I (mtCOI) gene. Over course three consecutive years, 111 were collected from different geographical regions hosts Jordan. The results showed th...

This study reports on the molecular identification of fish species from processed products which had a priori been classified as belonging to 5 important species in Iran for human consumption. DNA barcoding using direct sequencing of an approximately 650bp of mitochondrial Cytochrome oxidase subunit I (COI) gene revealed incorrect labeling of Narrow-barred Spanish mackerel samples. High occurre...

cattle have an important role in primary human civilization, so molecular studies for more accurate recognition of their origin are effective to identify unknown historical aspects. cattle can be divided in to 2 main groups including bos tuarus and bos indicus. both types of cattle can be found in iran; therefore study of their origin has particular importance. the aim of this study was to inve...

One of the top species in aquaculture sector, known as striped catfish or Pangasianodon hypophthalmus, is an important and valuable freshwater fish many countries. Due to high demand for this species, their number has declined "threatened" levels. Hence, purpose study analyse genetic variation wild cultured collected from five producers Asian countries; Thailand, Vietnam, Indonesia, India, Phil...

We tested the mitochondrial DNA cytochrome b gene-based (1065 bp.) phylogeny and genetic diversity of tooth-carp fish (Aphaniidae Hoedeman, 1949 family), many which are endemic, with a very high species in Anatolia. A total 107 individuals were studied from 29 stations belonging to 19 Aphaniid species. For Cytb gene, 44 haplotypes identified, all species-specific. The phylogenetic relationships...

A polycephalic larva of Taeniidae family isolated from abdominal cavity of a great gerbil (Rhombomys opimus) from Golestan province, northern Iran, was subjected to molecular analysis. Genomic DNA from the larva was obtained using a DNA extraction tissue kit. Polymerase chain reaction was performed for amplification of the partial 12S rRNA, cytochrome c oxidase subunit 1 (cox1...

Two cichlid populations each found on separate islands in the Bocas del Toro archipelago, Panama were identified as members the genus Astatheros. DNA from each population was isolated and purified and the mitochondrial gene cytochrome b was used as a molecular marker. Resulting sequences were compared with already published cytochrome b sequences of Astatheros from an internet database. Phyloge...
