the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
The genetic diversity of 20 Iranian populations of Bunium persicum has been evaluated with random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers. Fresh leaves of seedlings from each population were used for genomic DNA extraction. Analysis of banding patterns of 15 RAPD primers and 17 AFLP primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
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...
Having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. In present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and RAPD markers. Significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
the genetic structure of the genus alburnus is not well known and the phylogenetic relationships among its species are uncertain. in the present study, simple sequence repeats (ssrs or microsatellites) were used to evaluate genetic diversity and genetic differentiation between alburnus mossulensis heckel, 1843 from kashgan river in lorestan province and alburnus caeruleus heckel, 1843 from gama...
