The putative replication initiation protein (Rep) of Coconut foliar decay virus (CFDV) was expressed as a 6x His recombinant protein in E. coli and in recombinant baculovirus. Purified 6x His-Rep protein was demonstrated to possess sequence non-specific RNA- and ssDNA-binding activities as well as magnesium-dependent ATPase/GTPase activity. The yeast two-hybrid system revealed that CFDV Rep cou...
As their names imply, parvoviruses of the genus Dependovirus rely for their efficient replication on the concurrent presence of a helpervirus, such as herpesvirus, adenovirus, or papilloma virus. Adeno-associated virus 2 (AAV2) is such an example, which in turn can efficiently inhibit the replication of each helpervirus by distinct mechanisms. In a previous study we have shown that expression o...
Nucleic acid polymers (NAPs) block the release of subviral particles from hepatocytes, a mechanism consistent with their antiviral activity against hepatitis B virus (HBV) in patients. Analysis of immunostimulatory properties of NAPs were conducted with several NAP species: REP 2006, the prototypic degenerate NAP [dN]40, containing TLR9-stimulatory CpG; REP 2055 a clinically active NAP with a s...
pseudomonas syringae pv. syringae (pss) با دارا بودن بیش از 180 میزبان، بعنوان یکی از مهمترین بیمارگرهای گیاهی تلقی شده و سالیانه خسارات قابل توجهی را در سراسر دنیا به محصولات مختلف وارد می کند. به منظور بررسی خصوصیات ژنوتیپی باکتری مذکور، 58 جدایه از میزبان های مختلف شامل هسته داران، غلات، دانه داران، برخی علف های هرز و گیاهان زینتی در استان های فارس، کهگیلویه و بویراحمد، چهارمحال و بختیاری و ...
Replication initiation of nanoviruses, plant viruses with a multipartite circular single-stranded DNA genome, is triggered by the master Rep (M-Rep) protein. To enable the study of interactions between M-Rep and viral or host factors involved in replication, we designed oligohistidine-tagged variants of the nanovirus Faba bean necrotic yellows virus (FBNYV) M-Rep protein that allow affinity pur...
سابقه و هدف: جنس آزوسپیریلوم شامل ریزوباکتریهای آزادزی، تثبیتکنندهی نیتروژن و محرک رشد گیاه هستند که می-توانند رشد و عملکرد بسیاری از محصولات زراعی مهم از جمله برنج و گندم را تحت تأثیر قرار دهند. این مطالعه با هدف جداسازی و شناسایی گونههای بومی مختلف آزوسپیریلوم و بررسی تنوع ژنتیکی آنها به عنوان عوامل محرک رشد گیاه انجام شد.مواد و روشها: در این مطالعه نمونههای خاک و ریشهی مزارع گن...
DNA helicases catalyze separation of double-helical DNA into its complementary single strands, a process essential for DNA replication, recombination, and repair. The Escherichia coli Rep protein, a superfamily 1 DNA helicase, functions in DNA replication restart and is required for replication of several bacteriophages. Monomers of Rep do not display helicase activity in vitro; in fact, DNA un...
Listeria monocytogenes strains possess short repetitive extragenic palindromic (REP) elements and enterobacterial repetitive intergenic consensus (ERIC) sequences. We used repetitive element sequence-based PCR (rep-PCR) to evaluate the potential of REP and ERIC elements for typing L. monocytogenes strains isolated from humans, animals, and foods. On the basis of rep-PCR fingerprints, L. monocyt...
