Genetically modified wheat has not been commercially utilized in agriculture largely due to regulatory hurdles associated with traditional transformation methods. Development of marker-free transgenic wheat plants will help to facilitate biosafety evaluation and the eventual environmental release of transgenic wheat varieties. In this study, the marker-free transgenic wheat plants previously obtained by Agrobacterium-mediated co-transformation of double T-DNAs vector were identified by fluoresce...
