Fig. 4From: Characteristic analysis of BpbZIP family genes and BpbZIP26 significantly enhanced triterpenoid production in Betula platyphylla under S-nitrosothiol treatmentGene structures of the BpbZIP genes. (a) The phylogenetic tree of 51 BpbZIP proteins. (b) 20 motifs in the BpbZIPs were represented by different colored boxes. (c) Exon/intron structures of BpbZIP genes. Yellow boxes, blue boxes, and gray line indicated exons, untranslated regions (UTR), and introns at each BpbZIP gene, respectivelyBack to article page
