METHOD FOR CULTIVATING PLANT RESISTANT TO GRAY LEAF SPOT

The present invention discloses a method for cultivating a plant resistant to gray leaf spot. The proteins provided by the present invention are obtained from maize and named as ZMPK protein， and are the proteins represented by seq. 2， seq. 4， seq. 7 or seq. 9 in the sequence list. Nucleic acid molecules encoding the ZMPK proteins are also within the scope of the present invention. The invention further sets forth a method for preparing a transgenic plant， comprising the step of: introducing the nucleic acid molecules into a starting plant to obtain the transgenic plant with reduced resistance to gray leaf spot. The invention further sets forth a method for preparing a transgenic plant， comprising the step of: knocking out or inhibiting the expression of the nucleic acid molecules in a starting plant to obtain the transgenic plant with increased resistance to gray leaf spot. The present invention is of great application value to the breeding of maize resistant to gray leaf spot.
