Maximum Likelihood (ML) phylogenetic tree constructed using IQ-TREE 1.6.12 based on nearly complete genome sequences [open reading frames (ORFs) 0–5] from 50 sugarcane yellow leaf virus (SCYLV) isolates. ML analysis was carried out using nucleotide identity distances and 1000 bootstrap replicates (Bootstrap values > 60% are shown at nodes). The scale bar indicates the number of substitutions per nucleotide. Different geographic regions are represented with red, green, and purple lines for Asia (filled square), Africa (filled circle), and America (filled triangle), respectively. The six SCYLV isolates from sugarcane obtained in the present study are indicated by the solid pentagram (filled star). A potato leafroll virus (PLRV; NCBI accession no. NC_001747) isolate served as an outgroup (filled diamond). The acronyms of each SCYLV genotype based on their originally geographical origins: BRA (Brazil), HAW (Hawaii), PER (Peru), CHN (China), REU (Reunion), FLA (Florida), IND (India), and CUB (Cuba).
