Abstract: (11 Views)
Members of the genus Garra, with about 185 species, are one of the most diverse genera of Cyprinidae, which is widely distributed from Southeast Asia to West Africa. Approximately 43 species of this genus have been recorded from the Middle East. This study investigated the molecular systematics of this genus in the Middle East based on mitochondrial cytochrome oxidase 1 sequences. For this purpose, 78 sequences were obtained from the GenBank. Maximum likelihood and Bayesian trees were constructed with 10,000 bootstrap replicates and 25,000,000 generations, respectively, in RaxML and MrBayes software. Genetic distances between the studied species were calculated. The PTP and mPTP model-based species delimitation approaches were determined. Phylogenetic tree results place species of this genus in their specific clades, while species delimitation results based on the PTP model combine a number of species and introduce them as a single entity, which is consistent with the results of other molecular studies. Therefore, the results of the analysis of COI sequences provide very suitable information for investigating the systematic status of the genus Garra, in addition to which, the use of other genetic sequences, including mitochondrial and nuclear, as well as morphological features, is also recommended for a comprehensive assessment of the systematic status of this genus.
