Phylogenetic tree using the NJ method displaying the relationships among the AP2/ERF family of L. chinense. The phylogenetic tree was constructed using AP2/ERF domain sequences by the NJ method with 1000 bootstrap replicates in MEGA 7.0. The evolutionary distances were computed using the Poisson model. All 104 LcERF proteins were categorized into four subfamilies, including the ERF, AP2, RAV, and Soloist subfamilies. The ERF subfamily members were further divided into DREB subfamily (Groups I, II, III, IV) and ERF subfamily (Groups V, VI, VII, VIII, IX, X, VI-L)
