| Even though much improvement has been made in plant transformation methods, the screening of transgenic plants is often a laborious work. Most approaches for detecting the transgene in transformed plants are still timeconsuming, and can be quite expensive. The objective of this study was to search for a simpler method to screen for transgenic plants. The infiltration of kanamycin (100 mg/mL) into tobacco leaves resulted in conspicuous chlorotic spots on the non-transgenic plant leaves, while no spots were seen on the leaves of transformed plants. This reaction occurred regardless of age of the tested plants, and the method has proven to be simple, fast, non-destructive, relatively cheap, and reliable. These results were comparable to those obtained by the... |

| Genetically modified organisms (GMOs) such as soybeans and corn have garnered considerable consumer attention due to the concern over potential effects from using these commodities as inputs into food production. In the simplest form, segregation of bioengineered and non-bioengineered crops is an identity-preserved system. For these identity-preserved systems to exist, there must be a market discovery mechanism in place whereby supply and demand factors interact to establish a market price. In May 2000, the Tokyo Grain Exchange began a nongenetically modified organism (non-GMO) soybean contract. This article describes information garnered from the first public-offered identity-preserved marketplace. |

| In recent years scientific literature has seen an increase in publications describing new transgenic applications. Although technically-sound, these promising developments might not necessarily translate into products available to the consumer. This article highlights the impact of external factors on the commercial viability of Genetically Modified (GM) animals in the pharmaceutical and food sectors. Through the division of the production chain into three Policy Domains -Science, Market and Public- I present an overview of the broad range of regulatory and socio-economic components that impacts on the path towards commercialisation of GM animals. To further illustrate the unique combination of forces that influence each application, I provide an in-depth... |

| ABSTRACT This study aimed to evaluate the development and reproduction of the black armyworm, Spodoptera cosmioides when larvae fed on leaves of Bt-corn hybrids, expressing a single Cry1F and also Cry1F, Cry1A.105 and Cry2Ab2 in pyramided corn and their non-Bt-isoline (hybrid 2B688), as well as on leaves of two soybean isolines expressing the Cry1Ac protein and its non-Bt isoline (A5547-227). We also assessed the effect of these Bt and non-Bt plants on the leaf consumption rate of S. cosmioides larvae. This pest was unable to develop when fed on any of the corn isolines (Bt and non-Bt). When both 1st and 3rd instar larvae were fed on corn leaf, mortality was 100% in both Bt and non-Bt corn. In contrast, when corn leaves were offered to 5th instar larvae,... |

| This paper analyzes the current and proposed biosafety systems in Kenya, Tanzania, and Uganda using a set of components and characteristics common to functional and protective biosafety regulatory systems. It also assesses how those systems take into account the major international legal obligations that relate to biosafety, such the Cartagena Biosafety Protocol. The paper identifies certain areas in each country’s biosafety regulatory systems where further development and clarification would improve the biosafety system, making it more functional and protective. Those areas include: (1) the addition of procedures to ensure the food safety of genetically engineered organisms; (2) the inclusion of the standard and criteria for making an approval decision;... |

| Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation systems prior to release of GM varieties. In this study, a stochastic optimization model was developed to determine optimal testing strategies. The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system. Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain. The model... |

| Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation (IP) systems prior to release of GM varieties. In this study, a stochastic optimization model was developed to determine optimal testing strategies.

| The economical, environmental and social impacts associated with genetically modified (GM) crops are supported by the increased use of GM species by farmers. This increase in the use of GM species has included a global increase in both the number of hectares with GM crops and the number of countries using this technology. However, the use of GM crops has some drawbacks, due to the environmental risks associated with some of the events and social risks related to intellectual property rights issues and the monopoly associated with this technology. An overview of the current status of the use of GM crops in relation to the production, benefits, associated risks, intellectual property rights, legislation and regulatory framework is presented, focusing in the... |
