Abstract

To investigate the activity of the regulatory region of the maize (Zea mays L.) proteinase inhibitor (mpi) gene, we transferred into rice (Oryza sativa L.) plants the -689/+197 (C1) fragment of the mpi genomic clone fused to either the uidA gene or a synthetic Bacillus thuringiensis cry1B gene. Although uidA and cry1B encode very different proteins consistent results were obtained from their respective histochemical and fluorometric and immunoblot detections in T3 transgenic rice lines. In response to mechanical wounding, a 4-5 fold increase in GUS activity and a Cry1B accumulation reaching 0.1-0.2% of total soluble proteins were observed from basal and undetectable levels respectively in leaf tissue. The establishment of the time-course of wound response in both systems revealed a maximum induction level 12-16 h after treatment. From both systems we also deduced that the C1 region is not active in pollen and seed endosperm. Three independent transformation events expressing cry1B under the control of the C1 region exhibited protection against striped stem borer damage and showed 100% mortality of second instar larvae 8 days after release. These results illustrate the first evidence that wound-inducible expression of a Bacillus thuringiensis endotoxin gene affords full protection to transgenic rice plants.

  • The feasibility of using wound-inducible promoters to drive cry genes has been documented in glasshouse and field for rice where cry genes were driven by the wound-inducible mpi promotor from maize.

    “The feasibility of this approach has been documented in the glasshouse and in the field for rice where cry genes were driven by the woundinducible mpi promotor from maize (Breitler et al., 2001(Breitler et al., , 2004).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
