Black Pomfret (Parastromateus niger) is one of the commercially important pelagic fishes of the southern coasts of Iran. Its stocks are decreasing due to over exploitation, pollution and lack of fishing management programs. In order to assess the population size of this species and to preserve its valuable genetic resources, genetic structure of 32 fish samples was investigated using AFLP marke...

Malus transitoria (Batalin) C. K. Schneider is a shrub or small tree species native to in and around the Qinghai-Tibetan Plateau (QTP). Using 18 pairs of EST-SSR markers, we examined 142 samples from 8 wild populations M. obtained QTP. Genetic diversity had been high at level showed mean expected heterozygosity (He) Shannon's information index (I) per population were 0.573 0.921, as well geneti...

Pomegranate (Punica granatum L.) is a multipurpose plant that is important as nutrition, medical, horticulture, landscape and environment. The plant has been cultivated since old Iran and Egypt which is mentioned in Bible and Quran. Origin of the plant is Iran and some neighbour countries, although it is cultivated in many countries, now a day. Botanically, it is classified in Punicaceae and ha...

Survey of genetic diversity is essential for breeding program. The genetic diversity of A. andreanum, 10 cultivars were analyzed using seven Start Codon Targeted (SCoT) and 40 RAPD markers in which 22 RAPD markers and all of SCoT marker produced polymorphic bands. Matrix genetic distance ranged from 0.01 to 0.37 for RAPD and from 0.02 to 0.52 for SCoT marker analysis. Polymorphism percentage ge...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

Along with the majority of Muslims in Iran, there are non-Muslim minorities with Iranian nationality. This article tries to explain the exclusive rights of religious minorities in Iranian political system; that means although religious minorities tend to be treated as the majority, they would like to preserve and protect their cultural-religious characteristics with the support of the governmen...

Many salmonid species have recently become at risk of extinction. For fish species where eggs cannot be cryopreserved, establishment of techniques to preserve genetic resources other than egg and embryo cryopreservation is imperative. In the present study, spermatogonia from male trout were transplanted into the peritoneal cavity of newly hatched sterile triploid salmon. Transplanted trout sper...
