Both the ecological adaptations of an organism and its evolutionary history are recorded in a genome. We used Agrobacterium biovar 1, a diverse group of plant-associated bacteria as a model to search for genomic signatures of ecological adaptation in relation to diversification. We designed a new phylogenetic approach accounting for horizontal transfer and duplication to reconstruct the evoluti...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Sorrel (Rumex acetosa L.) is a model dioecious plant in genetic and molecular studies for sex determination. In this research, gus reporter gene transformation to leaf disks of this plant via Agrobacterium tumefaciens was evaluated based on transient expression of this gene. Three strains of Agrobacterium( LBA4404, C58 and EHA101) and two kinds of bacterial suspensions (suspension I: Agrobacter...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...

Bovine chymosin enzyme is one of the most commonly used enzymes in the dairy industry. The production of this enzyme from its natural source does not meet the needs of this huge industry. The production of recombinant bovine chymosin in plants can be a good alternative to native enzyme. Insertion and expression of foreign genes in plants can occur in the nucleus and chloroplast organelles. The ...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
during plant infection, fungal pathogens secret polygalacturonase (pg) that are capable of degrading cell wall of susceptible plant tissues. polygalacturonase-inhibiting proteins (pgips) are able to specifically inhibit fungal polygalacturonases (pgs) activity. the inhibition of fungal pgs by pgips suggests that pgips have a role in plant tolerance to fungal infections. in this study bean (dane...
VirB5 is a type 4 secretion system protein of Agrobacterium located on the surface of the bacterial cell. This localization pattern suggests a function for VirB5 which is beyond its known role in biogenesis and/or stabilization of the T-pilus and which may involve early interactions between Agrobacterium and the host cell. Here, we identify VirB5 as the first Agrobacterium virulence protein tha...
agrobacterium tumefaciens is capable of gene transfer to both plant and non-plant organisms. indeed, upon infection of eukaryotic cells, agrobacterium tumefaciens transfers a piece of its tumor inducing (ti)-plasmid, called t-dna, to the host cell nucleus, which subsequently integrates into the host genome. the vird2 virulence protein which has relaxase endonuclease activities covalently binds ...
