  • Patent number: 9085768
    Abstract: In this study, we used a wound-inducible promoter of the broccoli (Brassica oleracea var. italica) GLUCOSE INHIBITION of ROOT ELONGATION1 (GIR1) gene fused to ?-glucuronidase (GUS, pBoGIR1::GUS) as a selectable marker. Transgenic broccoli plants expressing pBoGIR1::GUS appear blue in planta at wounded regions after GUS staining for 30 min. Similarly, the blue color is visible in transgenic Arabidopsis and rice plants expressing pBoGIR1::GUS at wounded areas after GUS staining for 2 h, indicating that this promoter is wound-inducible in both dicots and monocots. GUS staining is very rapid and the partial wounding in this study is a nondestructive method that does not affect further plant growth and development. Thus, pBoGIR1::GUS could serve as an effective substitute for antibiotic- and herbicide-resistance genes in the generation of genetically modified crops.
