摘　　要：0 引言.河南省是我国玉米小麦的种植大省,玉米和小麦的种植面积常年保持在3 800千公顷和5 670千公顷以上。玉米黄花叶病毒(maize yellow mosaic virus, MaYMV)是2016年在我国云南省玉米上首次发现的一种新病毒[1],属于马铃薯卷叶病毒属(polerovirus),能够引起玉米植株叶片黄化、花叶、红叶等症状[6],之后该病毒在亚洲[1-2]、非洲[3-4]、南美洲[5]等地区禾本科作物上均有发现.Maize yellow mosaic virus(MaYMV)as a newly identified polerovirus causes leaf reddening on maize and yellow dwarf on wheat,leading to severe economic loss.In this study,maize and wheat leaf samples showing viral symptoms were collected in 11 different regions in Henan province in 2022.Analysis results of their full length coat protein nucleotide and amino acid sequence showed that MaYMV was commonly distributed in Henan province with the highest detection rate of 100%in wheat from Zhumadian and Xinxiang;66.7%in maize from Zhengzhou.The amino acid identity was high between different isolates with a variation rate between 0-2.0%.Further phylogenetic analysis showed that the maize and wheat isolates of MaYMV were clustered into a major branch.This study lays a foundation for the surveillance and control of MaYMV.
