A highly N-phosphonomethylglycine (glyphosate)-resistant Pseudomonas fluorescens G2 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) was mapped to identify potential split sites using a transposon-based linker-scanning procedure. Intein-mediated protein complementation was used to reconstitute glyphosate resistance from the genetically divided G2 EPSPS(More)
The potential impact of transgene escape on the environment and food safety is a major concern to the scientists and public. This work aimed to assess the effect of intein-mediated gene splitting on containment of transgene flow. Two fusion genes, EPSPSn-In and Ic-EPSPSc, were constructed and integrated into N. tabacum, using Agrobacterium(More)
Sweet sorghum [Sorghum bicolor (L.) Moench] accumulates large amounts of sugars in the stem parenchyma and can be used to manufacture sucrose and alcohol. Soluble acid invertase (SAI) plays an important role in sucrose accumulation in the sweet sorghum stem. Characterization of SAI genes and development of functional markers are important for(More)
