Fig. 5From: Characteristic analysis of BpbZIP family genes and BpbZIP26 significantly enhanced triterpenoid production in Betula platyphylla under S-nitrosothiol treatmentCis-elements in the promoter regions of BpbZIPs. The 2.0 kb promoter region located upstream of each BpbZIP gene was used to predict by PlantCARE. The number of different kinds of cis-elements were represented with the colored circleBack to article page
