Distribution of maize yellow mosaic virus on wheat and maize in Henan Province and variation of their CP sequences
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.
