| This research report highlights the findings from a set of studies undertaken by the International Food Policy Research Institute, along with several national and international research institutions, to assess the economic impact of improved cultivars and management practices on smallholder farmers in the Lake Victoria Region of Uganda and Tanzania— an area where the cooking banana is both economically and culturally important. Genetic transformation is a promising alternative for improving the resistance of banana plants to the pests and diseases that cause serious economic losses, because bananas, unlike rice, wheat, and maize, are difficult to improve through conventional breeding techniques. The team of researchers posed three broad questions: What is... |

| 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;... |

| Cyanobacteria display a large diversity of cellular forms ranging from unicellular to complex multicellular filaments or aggregates. Species in the group present a wide range of metabolic characteristics including the fixation of atmospheric nitrogen, resistance to extreme environments, production of hydrogen, secondary metabolites and exopolysaccharides. These characteristics led to the growing interest in cyanobacteria across the fields of ecology, evolution, cell biology and biotechnology. The number of available cyanobacterial genome sequences has increased considerably in recent years, with more than 140 fully sequenced genomes to date. Genetic engineering of cyanobacteria is widely applied to the model unicellular strains Synechocystis sp. PCC 6803... |

| Abstract: Early humans have domesticated plant and animal species based on ancient empirical concepts (Darwin 1868, 1876). In 1886, Mendel established a new paradigm of hereditary laws (Mendel 1866, 1870, 1950) based on genotypic and phenotypic traits of cross-compatible species, establishing a complex breeding technology that is currently utilized for the development of most food and livestock-derived products. Recently, studies on deciphering the double-helical structure (Watson and Crick 1953a, b) and how to restrict DNA (Arber 2012) have established the foundation of recombinant DNA technology. A new era is paving the way for genetic manipulation of important traits among all the kingdom’s organisms, allowing for the development of innovative and... |

| In the last 15 years, considerable advances were made in coffee genetic transformation. Different research groups in the world have been able to transform coffee with genes for insect resistance, decaffeinated coffee, herbicide resistance and control of fruit maturation. Although the majority of the research is still limited to laboratory and greenhouse studies, initial field tests with transformed coffee are beginning to appear in the literature. In this review we provide an update on the state of coffee genetic transformation, presenting technical aspects related to tissue culture systems, strategies for selection and transformation with particle bombardment, as well as the use of Agrobacterium tumefaciens. We also discuss the potential applications of... |

| Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's. The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined. Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use. On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use. Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use. |

| Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling disadvantaged production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific trait improvements. But these GM products can be installed on Green... |
