In this study phylogenetic relationship of the Jajrud River Brown trout Salmo trutta L. 1758 in the Namak Lake basin was analyzed using complete D-Loop sequence of the mitochondrial genome, compared to other Iranian populations of the species. The results clarified that Jajrud brown trout, similar to other Iranian brown trout populations belongs to the Danube phylogenetic lineage. The observed haplotype in the Jajrud population is similar to the reported haplotype in the Karaj River. Based on the results the Namak Lake basin brown trout affined to the Caspian populations and its relationship to Salmo macrostigma was not confirmed.  Since the Karaj and Jajrud River haplotypes have not been observed in the Caspian Sea basin and because of its relationship to other Iranian and Danube haplotypes it is plausible to consider this haplotype as an old haplotype that also may exist in the Caspian Sea basin. According to the biology of Brown trout, geographic characteristics, and based on the properties of the Namak haplotype it may be inferred that the Namak Basin Brown trout populations are native to the basin and are not introduced.

Garra rufa is one of the 73 Garra species of the family Cyprinidae. Scales are used more commonly than any other structure in population dynamic studies, because of their transparency, ease of sampling, and the minimal in-juries caused to the fish during their removal. To discriminate fish from different rivers including Bashar, Behbahan, Gerdab, Kheirabad, Kooshk-e-Bahram, Mazoo, Palangan, Sendegan, Shoor-Abad, and Sirvan Rivers using geometric morphometric analyses of the scale shape, landmark based geometric morphometrics method was used. Seven landmark points were depicted on each scale using the software TpsDig2. After procrustes analyses, landmark data were exposed to principle component analysis (PCA), CVA, and cluster analyses using the past software. The results showed that th-ere were significant scale shape differences among some populations, but most of the samples showed overlapping sh-ape distribution and could not be separated robustly. Among the samples which were analyzed, only the Sendegan and Gerdab river samples did not show significant difference in scale shape compared to all other samples.

Thirty eight ecotypes of watermelon were collected from different parts of Iran. After the preparation of the field, these eotypes were cultivated in a completely randomized block design with three replications. In order to invest-igate genetic diversity, genomic DNA samples were extracted from leaves and Polymerase chain reactions were optimized using 14 SRAP primer pairs. One hundred thirty six polymorphic bands were detected, of which the EM10-Me4 was the most abundant primer pair with 19 bands and EM16-Me4 and EM16-Me14 were the least primer pairs with 7 bands. PIC index varied from 0.20 to 0.32 and genetic diversity was 0.17 to 0.28 on the basis of Nei index. Fisher's Linear Detection Analysis showed that the UPGMA method and the grouping accuracy of about 90% are more appropriate than other cluster analysis methods. Cluster analysis, using Jakard method, was performed and the ecotypes studied were classified into five distinct groups. Based on the PCA, the first and second components included 92.5% of the variation, which represents the proper distribution of the markers on the whole genome.

S-layer proteins of Deinococcus radiodurans are the best self-assemble systems among other proteins that have an essential role in the fabrication of nanowires. Therefore, the purification of these proteins is necessary. The purpose of this research was to optimize the purification of s-layer protein from D. radiodurans with the response surface method. The three factors of SDS concentration, incubation time and mass percent in five levels were considered, and 20 runs were designed by Design-Expert software with a central composite method. Each run includes microbe culture, mass cell preparation, microbe incubation in specific SDS concentration and time and mass percent, separation of the bacteria from detergent with a centrifuge at 5000g, sedimentation of s-layer proteins from detergent solution with a centrifuge at 20000g, determination of protein concentration, and protein purity by Bradford and SDS-PAGE methods, respectively. Finally, the data obtained were analyzed.  Analysis of the results demonstrated that at the 95% confidence level, the effect of the detergent concentration factor on the purified protein percent was more than other factors. The optimization results of factors are 5.64% SDS concentration, 7.33% mass percent, and 3 hours incubation time. At optimized conditions the protein concentration and purity percent were obtained 0.584 mg/ml and 47.61% respectively.
