Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...

potato virus y (pvy) is one of the most important pathogenic agents that reduce the yield and quality of tobacco (nicotiana tabacum l.). dna-based molecular markers are valuable tools for identifying germplasm in gene banks, assessing kinship ties, and doing marker-assisted selection (mas) for resistance to pests, diseases, and some crop traits of interest. this work presents the results of ass...

abstract genetic diversity of german chamomile (matricaria chamomilla l.) populations in iran was evaluated using morphological, agronomical and phonological characteristics and compared with three cultivars from germany, hungary and iran. in this experiment, statistical design of rcbd with three replications was used, sixteen quantitative traits were measured such as yield, flower number per p...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

mimosa pudica lin., known as chue mue, is a stout straggling prostrate shrubby plant, with spinous stipules and globose pinkish flower heads, and grows as weed in almost all parts of the country. it is traditionally used for its various properties and hence in the present study, chloroform extract of mimosa pudica leaves has been screened for its hypolipidemic activity. hypolipidemic activity i...

morphological and rapd markers were used to investigate the genetic diversity among 21 accessions of pomegranate originating from south eastern tunisia. thirteen morphological traits were studied and results showed significant differences for all morphological characters (p< 0.001). clustering based on fruit traits, using ward’s method, divided the accessions into three main groups. in rapd ana...

iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. the amplified fragment length polymorphism (aflp) marker was applied to investigate the genetic variations among five major iranian melon cultigens (cucumis melo) and ‘ananasi’ as a general well-known cultivar. ten primer pairs were used on 90 indiv...

chamomile (matricaria chamomilla), an important medicinal plant belonging to the asteraceae family,has a wide distribution in iran and other parts of the world. the medicinal and pharmacological effects ofchamomile are mainly associated with its essential oil content and it is widely used in food, cosmetics andpharmaceutical industries. despite its wide geographical distribution in iran, little...

due to the significance of multiculturalism in politics, and the central role linguistic devices play in organizing the political discourse, this text-based qualitative study was carried out to compare political interviews in the iranian and english contexts to find out the probable similarities and differences in the use of discourse markers (dms) between the two cultures. to this end, three s...
