Method of enhancing plant resistance to geminiviruses by transformation with a SNF-1 polynucleotide

摘要

The present invention relates to a method of preparing transformed plant cells which are resistant to infection by a Geminivirus, comprising transforming said plant cells with a DNA construct comprising a polynucleotide that encodes a plant or yeast SNF-1 protein kinase and is operably linked to a promoter, and expressing said SNF-1 protein kinase in said plant cells. Also disclosed is a method for conferring viral resistance to plants, comprising regenerating the transformed plant cells to produce transgenic plants that express the SNF-1 kinase and are resistant to infection by Geminivirus.
