Abstract

We developed a new series of Gateway binary vectors for plant transformation, R4L1pGWBs, which allow easy construction of promoter:reporter clones. R4L1pGWBs contain a recombination attR4-attL1-reporter cassette, and thus an attL4-promoter-attR1 entry clone was efficiently incorporated by the Gateway LR reaction, resulting in the generation of an attB4-promoter-attB1-reporter construct. The reporters employed in R4L1pGWBs were β-glucuronidase (GUS), luciferase (LUC), enhanced yellow fluorescent protein (EYFP), enhanced cyan fluorescent protein (ECFP), G3 green fluorescent protein (G3GFP), G3GFP-GUS, and tag red fluorescent protein (TagRFP).
