BACKGROUND In part due to the ease of visual detection of phenotypic changes, anthocyanin pigment production has long been the target of genetic and molecular research in plants. Specific members of the large family of plant myb transcription factors have been found to play critical roles in regulating expression of anthocyanin biosynthetic genes and these genes continue to serve as important t...

fusarium wilt caused by fusarium oxysporum f.sp. lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. in order to increase the tolerance to this disease, a triple structure containing pr1, chitinase and glucanase genes controlled by 35s promoter was transferred to tomato. eight days after planting on pre-culture medium, exp...

expansin proteins are a type of cell-wall loosening proteins which able to cell wall expansion in ph-dependent manure without hydrolyze of main cell wall structures. the arabidopsis expa1 exhibit guard cell specific expression and trigger the stomatal movements. the objectives of this study were to transfer the atexpa1 gene into tobacco plants and evaluate their phonotypic effects on transforme...

introduction lentil is an important pulse crop in iran. lentil is a seed propagating, self-pollinating crop originating from near east. it is containing 27.5% -31.75% protein and it has high level of iron, calcium, phosphor, thiamin, niacin, and some unusual amino acid as hydroxyarnitin, hydroxyarginin and homo arginin. faostat reported that the world production of lentils was 4,975,621 metric ...

abstract the purpose of this research was to transform two economically important cultivars of strawberry with p5cs gene, which encodes δ1-pyrroline-5-carboxylate synthetase (p5cs), the key enzyme in proline biosynthesis. shoots were obtained on ms basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa and kurdistan cultivars. for genetic transformation, a binary vector pbi121 co...

to investigate the impact of overexpression of atnrt2.1 transgene from arabidopsis on nitrate uptake rate and to understand the regulation of endogenous hats by nitrate and glutamine amino acid (gln) in tobacco plants, wild-type and transgenic (f line) plants grown on soil for 4 weeks were transferred to hydroponic culture in a controlled-environment with a 16/8h l:d photoperiod at 24? c/20...
