the engineering of transgenic canola (brassica napus l. ) to make tolerance to the broad-spectrum herbicide, glyphosate, is one of the most effective approaches for weed management. glyphosate inhibits the enzyme epsps (5-enolpyruvylshikimate-3-phosphate synthase) enzyme which functions in the shikimate pathway and has a key role in biosynthesis of aromatic amino acids required for survival of ...

Abstract Clarias gariepinus growth hormone ( Cg GH) transgenesis was previously used to develop a population of second-generation (G 2 ) transgenic mutiara catfish C. ). The third generation these fish (1-month old fingerlings) had 2–3 times improvement in compared non-transgenic the commercial feed test for 6 weeks rearing. We assessed impact GH transgene expression on and protein amino acid c...

the most popular animal models of alzheimer’s disease (ad) are transgenic mice expressing human genes with known mutations which do not represent the most abundant sporadic form of the disease. an increasing number of genetic, vascular and psychosocial data strongly support that the octodon degus, a moderate-sized and diurnal precocial rodent, provides a naturalistic model for the study of the ...

environmental stresses trigger a wide variety of plant responses, such as altered gene expression to changes in cellular metabolism and growth. the several plant reactions exist to circumvent the potentially harmful effects caused by light, drought, salinity, pathogen infections and other stresses. a-tocopherol is the major vitamin e compound found in leaf chloroplasts. this antioxidant deactiv...

polychlorinated biphenyls (pcbs) are chlorinated biphenyl rings that due to their properties such as heat resistance and stability were widely used in different industries from 1920s to 1980s. due to their characteristics such as stability, resistance to decomposition and harmful effects on human health, their production was banned in 1980s., worldwide contamination of water and soil with pcbs ...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

conclusions in conclusion, ctp-hbcag18-27-tapasin could reduce apoptosis of cd8+ t cells, increase the percentages of ifn-γ+ cd8α+ t cells, and elicit cell-mediated immunity in hla-a2 transgenic mice; these processes were associated with activation of the pi3k/akt signaling pathway. results the results showed that ctp-hbcag18-27-tapasin significantly increased the percentages of ifn-γ+ cd8α+ t ...

It has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. Plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

conclusions by employment of gene optimization strategies, use of viral-based vectors and suppression of plant-derived gene silencing effect, efficient transient expression of hcvcp in tobacco with proper antigenic properties could be possible. background hepatitis c virus (hcv) is major cause of liver cirrhosis in humans. hcv capsid (core) protein (hcvcp) is a highly demanded antigen for vario...

in this study, an efficient agrobacterium-mediated transformation method was developed forpomegranate (punica granatum l.), a difficult-to-transform plant. in vitro shoot segments wereinoculated with agrobacterium tumefaciens strain lba4404 harboring the binary vectorpbi121 carrying the neomycin phosphotransferase (nptii) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter....
