This study established a new system for potato transformation using toxoflavin as selection agent and toxoflavin lyase (tflA) as selectable marker gene. Potato plants expressing tflA was successfully transformed on toxoflavin medium with 27% efficiency, similar to that for the hygromycin/hpt selection system. The transgenic potato expressing tflA also showed resistance to Burkholderia glumea in...
Transgene technology provides a powerful tool for developing traits that are otherwise difficult to achieve through conventional methods. The development of transgenic plants requires the use of selectable marker genes, as the efficiency of plant transformation is less than optimal for many important species, especially for monocots such as durum wheat (Triticum turgidum var. durum). Many conce...
presence of antibiotic resistance markers has always been considered as one of the main safety concerns in transgenic plants and their derived products. elimination of antibiotic selectable markers from transgenics is a major hurdle for finding efficient and safe candidates. herbicide tolerance genes might be attractive alternatives. in this study, a variant form of the 5-enoylpyruvyl shikimate...
A three-plasmid yeast expression system utilizing the portable small ubiquitin-like modifier (SUMO) vector set combined with the efficient endogenous yeast protease Ulp1 was developed for production of large amounts of soluble functional protein in Saccharomyces cerevisiae. Each vector has a different selectable marker (URA, TRP, or LEU), and the system provides high expression levels of three ...
The development of selectable markers for transformation has been a major factor in the successful genetic manipulation of plants. A new selectable marker system has been developed based on bacterial gentamicin-3-N-acetyltransferases [AAC(3)]. These enzymes inactivate aminoglycoside antibiotics by acetylation. Two examples of AAC(3) enzymes have been manipulated to be expressed in plants. Chime...
In this study, an efficient Agrobacterium-mediated transformation method was developed forpomegranate (Punica granatum L.), a difficult-to-transform plant. In vitro shoot segments wereinoculated with Agrobacterium tumefaciens strain LBA4404 harboring the binary vectorpBI121 carrying the neomycin phosphotransferase (nptII) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter....
