Fig. 1From: Identification of WRKY transcription factor family genes in Pinus massoniana Lamb. and their expression patterns and functions in response to drought stressPhylogenetic tree analysis of PmWRKYs in P. massoniana. Reconstructed phylogenetic trees for P. massoniana., Arabidopsis (At, 72), Pinus taeda (Pta, 20), and Picea glauca (Pgl, 16). Different colours represent different subfamilies. The phylogenetic trees were generated using MEGA 7 software and iTOLBack to article page
