The chemolithoautotrophic bacterium Nitrosospira multiformis is involved in affecting the process of nitrogen cycling. Here we report the existence and characterization of a functional quorum sensing signal synthase in N. multiformis. One gene (nmuI) playing a role in generating a protein with high levels of similarity to N-acyl homoserine lactone (AHL) synthase protein families was identified....
Many pathogenic bacteria use quorum sensing (QS) systems to regulate the expression of virulence genes in a density-dependent manner. In one widespread QS paradigm the enzyme LuxI generates a small diffusible molecule of the acyl-homoserine lactone (AHL) family; high cell densities lead to high AHL levels; AHL binds the transcription factor LuxR, triggering it to activate gene expression at a v...
چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...
among factors causing disagreement of shiites and sunnis is commentatorial hadiths. such hadiths are of great significance in the process of understanding as well as commenting on the quran–and even inferring juristic precepts. hence, attitude of muslims towards such hadiths play a significant role in the process of formation of their beliefs and inferring islamic precepts. attitude of sunn...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
In Gram-negative bacteria, quorum sensing is mediated by N-acylhomoserine lactones (AHL) to regulate different biological functions, including production of virulence factors. Quorum quenching refers to the interruption of quorum sensing, and the most attractive way is to degrade the AHL molecules. With the aim of isolating soil bacteria capable of blocking quorum sensing by inactivating AHL, a...
BACKGROUND Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food chain. Though vaccine against A. hydrophila is available, its use is limited due to multiple serotypes of this pathogen and problems of safety and ...
Mullah Mohsen Faiz-e-Kashani (996-1077 AH) is one of the great Imami thinkers in the second period of the Safavid dynasty in Iran, who is influenced by two views of Sadra and Hadith’s philosophy. He has presented his thoughts on politics by relying on the traditions of the Ahl al-Bayt (PBUT) and focusing on the virtues of Islamic philosophy. Thus, the main question of this article is how Feyz-e...
Citrobacter freundii strain ST2, isolated from the algae bloom sample, possesses an N-acylhomoserine lactone (AHL) production activity that secretes short-chain AHL molecules. In this study, we sequenced the complete genome of C. freundii strain ST2 to understand the molecular regulation of the AHL system and to search for the AHL gene in this bacterium. The results show that the genome size is...
