Phylogenetic relationship of VcARF genes with the ARFs in other plant species. The sequences of publicly known ARF genes in Arabidopsis (23), apple (28), grape (26), tomato (25) and rice (25) were downloaded from NCBI (www.ncbi.nlm.nih.gov), TAIR (www.arabidopsis.org) or RAP-DB (https://rapdb.dna.affrc.go.jp/) database. A maximum likelihood tree was generated with the CDS sequences of 187 ARF genes using the MEGA7 software, which were clustered into 5 groups (I-V). The numbers indicate the bootstrap values, which were calculated using 1000 replicates. The ARFs in the same species are represented with the same symbol: blue diamond, Vaccinium corymbosum; purple triangle, Vitis vinifera; dark purple triangle, Malus domestica; red triangle, Solanum lycopersicum; green triangle, Arabidopsis thaliana; light green triangle, Oryza sativa
