The increasing need for food can be met through an increase in crop productivity and reduction in pest associated losses. Recombinant DNA technology has created new avenues for genetic enhancement of crops through the development of transgenic plants with resistance to insects. Bacillus thuringiensis (Bt) genes have been widely used as candidate genes for genetic transformation of crop plants f...

Cloning technology is an emerging biotechnological tool that could provide commercial opportunities for livestock agriculture. However, the process is very inefficient and the molecular events underlying the technology are poorly understood. The resulting uncertainties are causing concerns regarding the safety of food products derived from cloned livestock. There are similar concerns for livest...

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...

cotton (gossypium hirsutum l.)  is an important fiber crop in iran, cultivated on 150000-200000 ha of land.  in iran the estimated loss due to the insect pest is more than 30%. traditionally, pests are controlled by 10-12 times spraying per growing season of environmentally harmful chemical insecticides (e.g. endosulfan and/or methosystox). in order to produce transgenic cotton resistance to in...

BACKGROUND Cadmium (Cd) is a major heavy metal pollutant which is highly toxic to plants and animals. Vast agricultural areas worldwide are contaminated with Cd. Plants take up Cd and through the food chain it reaches humans and causes toxicity. It is ideal to develop plants tolerant to Cd, without enhanced accumulation in the edible parts for human consumption. Glutathione transferases (GST) a...

abstract background: selectable marker gene (smg) systems are critical for generation of transgenic crops. transgenic crop production background: selectable marker gene (smg) systems are critical for generation of transgenic crops. transgenic crop production without using smg is not economically feasible. however, smgs are non-essential once an intact transgenic plant has been established. elim...

There is a new resolve, provoked by recent hikes in food prices around the world, to increase global food production in order to feed a rapidly growing population. In response made optimistic claims about the ability of genetically engineered (GE) crops changed using spliced genes that are often from unrelated organisms Agricultural biotechnology has shown to increase countries, far beyond the ...

Agouti-related protein (Agrp) encodes a hypothalamic neuropeptide that promotes positive energy balance by stimulating food intake and reducing energy expenditure. Agrp expression in the brain is restricted to neurons within the arcuate nucleus of the hypothalamus, and expression levels are elevated as a consequence of food deprivation. We tested a series of bacterial artificial chromosome repo...
