Methylotrophs bacteria are ubiquitous, and they have the ability to consume single carbon (C1) which makes them biological conversion machines. It is first study find facultative methylotrophic in contaminated soils Iraq. Conventional PCR was employed amplify MxaF that encodes methanol dehydrogenase enzyme. DNA templates were extracted from isolated five sites Basra. The gene specific detected ...

Avian interspecific brood parasites differ considerably in their commitment to parasitism; 87 species are obligate brood parasites, whereas 35 species are known to be facultative brood parasites. This variation is strongly related to mode of development. Obligate parasitism is found almost exclusively in altricial species, whereas facultative interspecific parasitism is predominant in precocial...

Many diploid organisms undergo facultative sexual reproduction. However, little is currently known concerning the distribution of neutral genetic variation among facultative sexual organisms except in very simple cases. Understanding this distribution is important when making inferences about rates of sexual reproduction, effective population size, and demographic history. Here we extend coales...

گسترش فعالیتهای صنعتی، ازدیاد جمعیت و دخالت بشر در محیط زیست میزان ورود فاضلابهای صنعتی، شهری و کشاورزی را به اکوسیستم های دریایی افزایش داده است. این فاضلابها حاوی آلاینده هایی از قبیل سموم کشاورزی، ازت، فسفر و فلزات سنگین می باشند. فلزات سنگین به علت پایداری و تجزیه ناپذیر بودن، قابلیت ورود به زنجیره های غذایی و تجمع زیستی در آبزیان از مهمترین آلاینده های دریایی محسوب می شوند. راهکارهای بسیار...

Facultative heterochromatin regulates gene expression, but its assembly is poorly understood. Previously, we identified facultative heterochromatin islands in the fission yeast genome and found that RNA elimination machinery promotes island assembly at meiotic genes. Here, we report that Taz1, a component of the telomere protection complex Shelterin, is required to assemble heterochromatin isla...

objectives: with side effects of antibiotics taken into consideration, the necessity of antibiotic therapy after simple implant placement procedures is still a subject of debate and the existing literature on this topic is widely controversial. the aim of this study was to assess the effect of postoperative amoxicillin therapy on early colonization of peri-implant sulcus after implant placement...

Brucella species are Gram-negative, facultative intracellular bacteria that cause zoonotic brucellosis. Survival and replication inside macrophages is critical for establishment of chronic Brucella infection. Virulent smooth B. abortus strain 2308 inhibits programmed macrophage cell death and replicates inside macrophages. Cattle B. abortus vaccine strain RB51 is an attenuated rough, lipopolysa...
