It has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. Plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

Antibiotic selectable marker genes have been widely used to generate transgenic animals. Once transgenic animals have been obtained, the selectable marker is no longer necessary but raises public concerns regarding biological safety. The aim of this study was to prepare competent antibiotic selectable marker free transgenic cells for somatic cell nuclear transfer (SCNT). PhiC31 intergrase was u...

We have developed a new plant vector system for repeated transformation (called MAT for multi-auto-transformation) in which a chimeric ipt gene, inserted into the transposable element Ac, is used as a selectable marker for transformation. Selectable marker genes conferring antibiotic or herbicide resistance, used to introduce economically valuable genes into crop plants, have three major proble...

Development of marker-free transgenic plants is a technical alternative for avoiding concerns about the safety of selectable marker genes used in genetically modified (GM) crops. Here, we describe the construction of a spontaneous self-excision binary vector using an oxidative stress-inducible modified FLP/FRT system and its successful application to produce marker-free transgenic rice plants w...

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....

Approximately fifty marker genes used for transgenic and transplastomic plant research or crop development have been assessed for efficiency, biosafety, scientific applications and commercialization. Selectable marker genes can be divided into several categories depending on whether they confer positive or negative selection and whether selection is conditional or non-conditional on the presenc...
