Salvia reuterana Boiss of the Labiatae family is naturally distributed in many parts of Iran. Recent pharmacological studies have confirmed some medicinal properties of S. reuterana including antibacterial, carminative and anti-oxidant effects. In order to domestication of this valuable plant, morphological diversity were studied among seven S. reuterana population (Absard, Delichai, Shahmirzad...
Rice Diversity PIC SSR marker Diversity at molecular level among thirty rice genotypes, selected based on earliness and morphometric diversity was evaluated through five SSR markers associated with days to heading. Three primers viz., RM147, RM167 and RM215 showed polymorphism for growth duration related traits. A total of 17 alleles were detected among the 30 rice genotypes with an average of ...
Genetic diversity of 45 wheat varietions were studied using AFLP markers. From 11 primer combinations of PstI and Mse1for obtaining AFLP polymorphism, six primer combinations (P-CGA/M-CTA, P-ATG/M-CTG, P-ATG/M-CAT, P-AGT/M-CTA, P-AGT/M-CAG and P-ATG/M-CAG) produced polymorphic bands. Totally, 328 bands be produced that 207 bands (63.10%) were polymorphic, which showing high polymorphism among g...
A biological assessment of the Tang Sorkh River (Iran) was studied from July 2013 to August 2014 using benthic macroinvertebrate communities. Samples were gathered every two months, from five stations using a Surber sampler( 30×30cm), fixed in formalin (4%) and then separated and identified in the laboratory. Environmental conditions (current velocity, temperature, depth, width, dissolve oxygen...
Morphological and molecular characterization of twenty six landraces rice and four high yielding rice accessions were studied to observe genetic diversity assessment and identification of superior genotypes for crop improvement program. Fourteen morphological and twenty seven DNA based molecular markers, simple sequence repeat (SSR), were used extensively to carry out this study. A wide range o...
The study site is located in an environmentally protected area known as an "APA" in São Pedro and Analândia, State of São Paulo, southeastern Brazil, whose watercourses are under strong anthropogenic pressure. Two basins were studied (sub-basin of the Corumbataí River and basin of the Jacaré-pepira River) with the purpose of characterizing the ichthyofauna of various streams, comparing fish div...
The genetic diversity of 19 bitter vetch landraces (Vicia ervilia L.) from four provinces (East Azerbaijan, West Azerbaijan, Ardabil and Zanjan) of Iran was evaluated using 18 pairs of SSR primers. The extracted genomic DNA was amplified with eight pair primers and PCR products were separated on DNA sequencing gels. In this research, eight pair of SSR primers detected a total of 27 alleles...
based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. this research was carried out in a part ofhighland mountainous rangeland of mount alborz range in iran. diversity and richnesswere assessed as an ecosystem health indicator. the study area was locate...
Extended Abstract Introduction and Objective: Medicinal plants have many applications in the treatment of humans, among which chamomile is one of the most valuable and widely used medicinal plants in the world. One of the most important breeding programs is the recognition of genetic diversity for the initial evaluation of plant masses. For this purpose, a study of genetic diversity and classi...
This study aimed to compare plant species diversity indices (diversity and richness) and some physico-chemical properties of soil among forest, ecotone and rangeland habitats. Vegetation sampling was done randomly at each habitat. One dominant community was selected in each habitat and one key area was distinguished in each community and 8×1m2 plots were randomly established in each key area. I...
