摘　　要：Maize(Zea mays L.)stands as one of the most extensively cultivated crops worldwide[1].With its widespread cultivation comes a plethora of challenges,including diseases caused by a wide range of pathogens[2].Gray leaf spot(GLS)is a foliar disease that drastically reduces worldwide maize production.Since it wasfirst identified in the US in the 1920s,the disease has spread around the globe,severely affecting corn production.GLS is predominantly instigated from infection by Cercospora zeae-maydis and Cercospora zeina[3].In many parts of China,GLS is an important disease[4].In severe cases,GLS can lead to a reduction of yield by up to 40%.Hence,it is urgent to control the spread of this disease[3].Developing and utilizing pathogen-resistant crop cultivars is the most economical and environment-friendly measure for controlling plant diseases.Scientists have dedicated significant efforts to characterize GLS resistance genes in maize.To date,ZmCCoAOMT2(caffeoyl-CoA O-methyltransferase 2)and ZmMM1(Mexicana lesion mimic 1)are the only two genes that have been shown to confer resistance to GLS[5,6].However,to facilitate the development of resistant cultivars,there is an urgent need for additional genes that are effective against GLS and a clearer understanding of the molecular mechanisms underlying the regulation of host plant resistance to GLS.
