Abstract |
: |
Some molecular markers (Inter simple sequence repeats or ISSR and Sequencing of some TMO-4C4 gene fragments) were developed to detect genetic signature and re-construct the phylogenetic relationships among some parrotfish species (CR-CQ = Leptoscarus vaigiensis, CI= Cetoscarus bicolor, CV= Calotomus carolinus, YSC= Scarus niger, YSE= Scarus ferrugineus) collected from the Red Sea, KSA. Genetic similarity and dissimilarity values among applied fish samples were calculated. The percentages of polymorphic bands were 42%, 8%, 11.5%, 15.5% and 28% in CR-CQ, CI, CV, YSC and YSE samples respectively. The evaluated TMO-4C4 gene nucleotide contents were calculated. A number of 63 polymorphic sites and 68 mutations were detected in the selected TMO-4C4 gene region. In addition, the GC contents (form 44.4% to 48.1%) and GC3 contents (from 35.1% to 36.6%) were calculated. The lowest genetic distance value was calculated between YSE and YSC fish species. The study outputs increased our scientific information about the parrotfish biodiversity in the Red sea, Saudi Arabia. Parrotfish genetic resources (in the Red Sea) needs more biological studies including molecular characterization for characterization and good management. Construction of research unit at KAU for Red Sea fish management was recommended. |
