  • Geminivirus-based gene expression system
    Patent number: 5981236
    Abstract: A geminivirus based vector system for obtaining controlled expression of a nucleic acid fragment of interest is disclosed. Tissue specific regulatory regions are identified employing cDNA screening and the resulting tissue-specific regulatory regions are manipulated for use in geminivirus constructs to provide for transcription and/or expression of nucleic acid sequences nonindigenous to the geminivirus vector for introduction into plant cells. The vector system may be used to provide transformed plants having cells, tissues or parts with a modified phenotypic property.
