Fig. 4From: Genome-wide identification and characterization of the SBP-box gene family in PetuniaPhylogenetic tree based on the cDNA sequence alignment of PhSPLs, PaSPLs, PiSPLs, PintSPLs and PeSPLs. PaSPL, the SPL genes of P. axillaris. PiSPL, the SPL genes from P. inflata. PintSPL, the SPL genes from P. intergrifolia. PeSPL, the SPL genes from P. exserta. The tree was generated with MEGA v6.0 software using the Neighbor-Joining (NJ) method and 1000 bootstrap replicatesBack to article page
