| 摘要 |
This invention is directed to the regulatory sequences of the pathogenesis-related (PR) protein genes of the PR-1 group, specifically an inducible PR-1 promoter and, preferably, PR-1 secretion signal sequences, and to genetic constructs containing the regulatory sequences. This invention also relates to the construction and use of a recombinant DNA molecule that includes a PR protein gene, and its regulatory sequences, including the promoter and secretion signal sequences. More specifically, the invention concerns the use of the recombinant DNA molecule that includes a PR-protein gene operably linked to PR protein regulatory sequences that upon expression in a plant will enhance the hypersensitive response of the plant to an invading pathogen. |
