Chimaeric genes can be constructed which fuse the transit peptide of a small subunit of the chloroplast-located ribulose 1,5-bisphosphate carboxylase with a bacterial protein. The fusion protein is translocated into chloroplasts and cleaved in a similar way to the small subunit polypeptide precursor.
Limitations in the current availability of bioenergy feed-stocks are a major problem in next-generation biofuels. There are global economic, political and environmental pressures to increase biofuel production and utilization, to offset gasoline and diesel fuel use, especially in the transportation sector. Many countries, such as the USA and China, have(More)
Light regulates many varied physiological and developmental phenomena during plant growth and differentiation, including the formation of a photosynthetically competent chloroplast from a proplastid. The expression of ribulose 1,5-bisphosphate carboxylase small subunit (rbcS) genes is regulated by light in a development- and tissue-specific manner2,3. In(More)
Done correctly, cellulosic bioenergy should be both environmentally and economically beneficial. Carbon sequestration and decreased fossil fuel use are both worthy goals in developing next-generation biofuels. We believe that biotechnology will be needed to significantly improve yield and digestibility of dedicated perennial herbaceous biomass feedstocks,(More)
Since their initial discovery, transposons have been widely used as mutagens for forward and reverse genetic screens in a range of organisms. The problems of high copy number and sequence divergence among related transposons have often limited the efficiency at which tagged genes can be identified. A method was developed to identity the locations of Mutator(More)
Sex determination in maize involves the production of staminate and pistillate florets from an initially bisexual floral meristem. Pistil elimination in staminate florets requires jasmonic acid signaling, and functional pistils are protected by the action of the silkless 1 (sk1) gene. The sk1 gene was identified and found to encode a previously(More)
Wide crosses have been used for decades as a method for transferring novel genetic material and traits in plant breeding. Historically, many products of wide crosses require tedious and inefficient surgical embryo rescue prior to embryo abortion to recover single plantlets. We have utilized transgenic switchgrass (Panicum virgatum L. cv Alamo) as a pollen(More)
Advanced genetic and biotechnology tools will be required to realize the full potential of food and bioenergy crops. Given current regulatory concerns, many transgenic traits might never be deregulated for commercial release without a robust gene confinement strategy in place. The potential for transgene flow from genetically modified (GM) crops is widely(More)
