Background and Objectives: Expression of genes related to biofilm formation in methicillin-resistant staphylococcus aureus (MRSA) can play an effective role in biofilm formation and pathogenicity. Due to the significance of antimicrobial activity of Artemisia species against biofilm producer genes, this study aimed to evaluate the effect of ethanolic extract of Artemisia oliveriana on the...
The results of diallel analysis of 7 parents and 21 F2 progenies of Burley tobacco cultivars, which were transplanted in 2002 as RCBD with 3 replications in the Tobacco Research Center, Rasht, Iran, showed significant genetic differences among genotypes and high GCA and SCA for most of the traits. Therefore the role of additive and non-additive (dominant) effects of genes on the formation of th...
Plant R-genes involved in gene-for-gene interactions with pathogens are expected to undergo coevolutionary arms races in which plant specificity and pathogen virulence continually adapt in response to each other. Lending support to this idea, the solvent-exposed amino acid residues of leucine-rich repeats, a region of R-genes involved in recognizing pathogens, often evolve at unusually fast rat...
Extracellular exosomes and preeclampsia: a microarray-based study and functional enrichment analysis
Background: Preeclampsia (PE) is a heterogeneous pregnancy disease which the exact pathophysiology of it is unknown. Recently exosomes have been indicated as a causative factor in the pathogenesis of PE. The aim of the study was to investigate in microarray library data to extract the differentially expressed genes (DEGs) in PE and to perform a functional enrichment analysis to predict the rol...
the present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (i/r) injury in rats.forty male rats were randomly divided into sham, control (i/r injury) and three crocin-pretreated groups. to induce i/r lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. pretreated-rats rec...
بیماری های گیاهی یکی از محدودیت های بزرگ در تولید محصولات کشاورزی به شمار می روند. نوار قهوه ای باکتریایی برنج با عامل acidovorax avenae subsp. avenae از جمله بیماری های برنج است که در خزانه روی برگ و غلاف گیاهچه ها نوارهای آبسوخته و قهوه ای ایجاد می کند. با توجه به این که در سال های اخیر استفاده وسیع از مواد شیمیایی در کشاورزی به منظور کنترل بیماری های گیاهی خطرات زیست محیطی زیادی را در پی داش...

wheat is a crop with spring and winter types and wide adaptability to different climate conditions. the wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (vrn) genes play pivotal role in determining spring and winter types. in this study, 395 iranian wheat landraces were characterized with specific primer pairs designed based on vrn-...
