Excision of a selective marker in transgenic rice using a novel Cre/loxP system controlled by a floral specific promoter

Abstract

Based on the Cre/loxP system, we have developed a novel marker-free system mediating a direct auto-excision of loxP-flanked marker genes from T1 transgenic rice without any treatment or further offspring crossing. To achieve this, the floral-specific promoter OsMADS45 was isolated from rice and the expression patterns of OsMADS45 promoter was characterised… (More)
