Precision of Transgene Integration by Site-Specific Recombination ! Possibility of site-specific recombination and homologous recombination process has been exploited in recent days to potentially increase transgene integration. It has been developed into the genetic engineering tool for higher eukaryotes. Despite the efficiency of using Agrobacterium for transformation, integration is still random and has no control over the impact of genomic [...]
In this article we will discuss about the transgenic strategy of stress in plants. In Arabidopsis, overexpression of cDNA encoding DREB1 and DREB2 triggered expresÂsion of many stress tolerance genes under normal growing conditions. Thus, transgenic stratÂegy resulted in increased tolerance to drought, salinity and cold stress. Researchers from Japan International Research Center for Agricultural Science (JIRCAS) identified 12 stress-inducible [...]
In this article we will discuss about the types of abiotic stress. Extreme environmental conditions such as drought, salinity and freezing temperature cause adverse effect on the growth and productivity of crop plants. The temperature (heat, chilling and freezing), drought and salinity stress together represent abiotic stress. Exposure of plants in general to these abiotic stresses is inevitable in nature [...]
