cotton cultivar coker has been already transformed with recombinant pbi121-chi via agrobacterium tumefaciens. the t-dna region of pbi121-chi carries the chitinase (chi ) gene from bean and is under the control of the camv35s promoter. t1 and t2 progenies of transgenic cotton containing the chi gene were used in this study. polymerase chain reaction (pcr), southern and western blotting data con...
ABSTRACT: Streptomyces sampsonii is a kind of biocontrol bacterium with antifungal effects, and chitinase one the main substances. To improve further study structure function gene S. sampsonii, we amplified target fragment by PCR, ligated to expression vector pET-32a, introduced resulting plasmid into Escherichia coli BL21 (DE3) induced chitinase. Then, recombinant was purified is-labelled prot...
potato (solanum tuberosum l.) an agro-economically important food crop in the world, is sensitive to many fungal pathogens including rhizoctonia solani (ag-3), the causal agent of stem and root rot diseases. chitinase and glucanase are cell wall degrading enzymes which have been shown to have high antifungal activity against a wide range of phytopathogenic fungi. in the present study, plasmid p...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
Thermostable chitinases are useful for industrial and biotechnological applications. This paper reports the stabilization of chitinase from Serratia marcescens B4A through rational mutagenesis. Changing of Ser 390 to Ile in S. marcescens. The stabilization was enhanced through entropic stabilization by reduction of the loop length and also by increasing of the beta chain length. With this repla...
Effects of induced mutation via gamma irradiated with 250 Gy dose (in Nuclear Agriculture Research School- Nuclear Science and Technology Research Institute) on Trichoderma harzianum conidiaon chitinase activity by STS molecular marker have been evaluated in this study. Among 20 irradiated mutants which selected via improved antagonistic capability against Rhizoctonia sola...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
Chitinases are hydrolytic enzymes that have been employed in biotechnology in attempts to increase plants' resistance against fungal pathogens. Genetically modified plants have given rise to concerns of the spreading of transgenes into the environment through vertical or horizontal gene transfer (HGT). In this study, chitinase-like sequences from silver birch (Betula pendula) EST-libraries were...
