Phylogenetic evidence for recombination among GLRaV-4 strains. Nucleotide sequence corresponding to (a) the CP, (b) ORF1a, recombinant regions identified for putative (c) event-1 (nt 4105–5240) and (d) event-2 (nt 627–1551) in ORF1a of the LR106 isolate, and (e) event-3 (nt 1–6312) in the Estellat isolate were used for constructing the Maximum-likelihood method-besed trees with 1000 replicates, using the MEGA 7 software. Recombinant isolates showing phylogenetic discordance are indicated in red color. Refer to Fig. 1b and Table 2 for details of putative recombinant event-1, event-2 and event3
