The distribution, phylogeny, and expression of VNS and SND2 genes. A Gene copy numbers (represented by dot size) in orthologous groups of VNS family and SND2 genes across 14 plant species. The dashed line marks the boundary between angiosperms and other plants. B–C Phylogenies of VNS (B) and SND2 (C) genes from 14 species. D Pie charts show the transcript detection of VNS and SND2 in each species. Darker color region in each pie chart represents the proportion of cells with detectable transcript abundance of VNS or SND2 genes. The proportion of darker color region in each pie is shown at the bottom-right. Light color region represents the proportion of cells with zero UMI of VNS or SND2 genes
