    • The subject invention concerns materials and methods for providing genetically-engineered resistance in plants to geminivirus, such as, using polynucleotides containing all or a portion of a replication associated protein (Rep) gene of TYLCV and all or a portion of a Rep intergenic region (IR). Virus-resistant plants produced according to the present invention have horticulturally acceptable phenotypic traits. Methods of the invention comprise transforming a plant with a polynucleotide wherein when the polynucleotide is expressed in the plant, the transformed plant exhibits resistance to plant viral infections. An exemplified embodiment utilizes a polynucleotide comprising a Rep gene derived from a Florida isolate of TYLCV. The methods of the invention can be used to provide resistance to TYLCV infection in plants such as tomato and tobacco. The present invention also concerns transformed and transgenic plants and plant tissue that comprise a polynucleotide of the invention.
    • 本发明涉及用于在植物中提供遗传工程抗性的双重病毒的材料和方法,例如使用含有TYLCV的全部或部分复制相关蛋白(Rep)基因的全基因组和全部或部分Rep基因间区域 IR)。 根据本发明产生的抗病毒植物具有园艺可接受的表型性状。 本发明的方法包括用多核苷酸转化植物,其中当多核苷酸在植物中表达时,转化的植物表现出对植物病毒感染的抗性。 示例性实施方案使用包含衍生自TYLCV的佛罗里达分离株的Rep基因的多核苷酸。 本发明的方法可用于提供植物如番茄和烟草中对TYLCV感染的抗性。 本发明还涉及包含本发明的多核苷酸的转化和转基因植物和植物组织。
