pistacia atlantica subsp. mutica is one of the most valuable forest tree species in iran that has been severely exploited for a long time. therefore, understanding the genetic diversity of different populations can be an important step towards the development and restoration of the habitat of this invaluable tree species. in this study, in order to study the genetic diversity, 10 populations in...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
Recogniting the genetic diversity and classification of inheritancepools is one of important activities in the field of breeding and maintaining genetic resources in plants. In order to assess the genetic diversity in 48 genotypes of soybean amplification of gene loci was performed by using 10 ISSR primers In Genetics and Plant Breeding laboratory, College of Agriculture andNatural Resources, U...
the following null hypothesis was proposed: there is no significant difference between the efl students listening comprehension development receiving pictorial cues and those receiving no cuse. to test the null hypothesis, 52 male and femal freshmen students of medicine studing at iran university of medical scinces were randomly selected from a total population of 72 students. to ensure that th...
Powdery mildew (Blumeria graminis f. Sp. Hordei) is one of the most destructive foliar diseases in barley that cause yield reduction worldwide. DNA molecular markers can be used to study the genetic diversity and better understanding of genetic predisposition to disease resistance to powdery mildew in barley at early growth stage. Selection of resistance and tolerance need to identify molecul...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
the effectiveness of irap, remap, ssr, and issr markers were investigated to assess genetic diversity among and within eight medicago sativa l. populations. a total of 101, 119, 117 loci and 31 alleles were amplified using 10 irap, 14 remap, 16 issr and eight ssr primers, respectively. irap markers generated the maximum proportion of polymorphic loci per primer (pplp) while the maximum value of...
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
abstract this study evaluated and compared medical terminology and english for the students of medicine (ii) as two representatives of the textbooks available on the iranian market for teaching english to the students of medicine. this research was performed on the basis of a teacher’s and a number of students’ attitudes and the students’ needs analysis for two reasons: first, to investigate...
