Fuente: WIPO "tomato" Use of a Glycine soja zinc finger protein 4 (GsZFP4) or a genetic material thereof are provided. A gene GsZFP4 encoding the GsZFP4 has the nucleotide sequence of SEQ ID NO: 1. A constructed plant overexpression vector pBA002-GsZFP4 is transformed into soybean. After 21 d of treatment with an SMV strain SC7, it is found that disease symptoms in the soybean overexpressing GsZFP4 are significantly alleviated and the SMV content is significantly reduced, demonstrating resistance to the SMV. In summary, the GsZFP4 may positively regulate soybean resistance to the SMV.
