background and aims: tomato yellow leaf curl virus (tylcv) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. in this study, the complete sequence of tylcv isolate from hormozgan province, iran and its recombination evsent was determined. methods: tylcv infected tomato was collected from hormozgan province. total d...

Medicinal use of the opium poppy (Papaver somniferum L) has ancient history, but the isolation of morphine was not described until the early nineteenth century. Morphine is the most important alkaloid of opium poppy in the last 50 years. In the morphine pathway has been reported to generate morphine in this species, CODM has a crucial role as the gene coding the enzyme respons...

In the 'omic' era, hundreds of genomes are available for protein sequence analysis, and some 30 per cent of all sequences are of membrane proteins. Unlike globular proteins, a 3D model for membrane proteins can hardly be computed starting from the sequence. Why is this so? What can we really compute and with what reliability? These and other matters are outlined.

  The problem of lot sizing, sequencing and scheduling multiple products in flow line production systems has been studied by several authors. Almost all of the researches in this area assumed that setup times and costs are sequence –independent even though sequence dependent setups are common in practice. In this paper we present a new mixed integer non linear program (MINLP) and a heuristic me...

Background: Members of this genus Aureobasidium are ubiquitous microorganisms which can be isolated from wide ranges of substrates such as plant materials (phyllosphere, plant debris, bark, roots, fruits and wood), soil, dead wood, air, and as rare etiologic agent of pheohyphomycosis, keratomycosis, septicemia, peritoneal sepsis, and dermatological infections in human. Very little is known on t...

Every year lots of black tea (Camellia sinensis (L.) Kuntze) residue will produce in the factories. These residue are unusable whereas the bio active compounds can be extracted and used in the drag and food industries. Due to mentioned problems, this project was conducted years 2011 - 2012 with the aim to make a study on consecutive isolation of all bio active compounds from tea residu...

Mycoplasma synoviae expressed variable lipoprotein haemagglutinin (VlhA) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. The aim of this study was sequencing Iranian M. synoviae isolates for the detection of nucleotide variation in the M. synoviae vlhA gene. Using oligonucleotide primers complementary to the single-copy conserved 5´ end...

Background: Lipophosphoglycan 3 (LPG3) is required for the LPG assembly, a well known virulent molecule. In this study, the LPG3 gene of the lizard and mammalian Leishmania species were cloned and sequenced. A three-dimensional structure (3D) for the target sequence was also predicted by comparative (homology) modeling. Materials and Methods: An optimization PCR amplification was performed o...
