Distribution and phylogenetics of SoSGV in China. a Distribution of SoSGV identified in various locations in China. The blue-colored region in the map represents China's main soybean production areas. The yellow-colored areas represent the provinces where SoSGV was identified in previous reports. The red-colored areas are the newly reported epidemic areas in this study. The locations where the samples were obtained in this study are written in bold font, followed by the number of SoSGV-positive samples over the total number of SGS samples collected (positive samples/total samples). b The unrooted phylogenetic tree was constructed based on the nucleotide sequence of the full-length genome of different SoSGV isolates. The tree was built with MEGA (version 11.0.11). The branch lengths represent the substitution rate per nucleotide site. Bootstrap values higher than 70 were given at the nodes. The accession numbers and the sampling locations are given for each isolate. Those 22 isolates with accession numbers OQ079694–OQ079715 are sequenced and reported in this study
