From: Overexpression of PtrABF gene, a bZIP transcription factor isolated from Poncirus trifoliata, enhances dehydration and drought tolerance in tobacco via scavenging ROS and modulating expression of stress-responsive genes

Figure 1

Multiple alignments of the deduced amino acid sequence of PtrABF and those of Arabidopsis thaliana (AtABF1, NP_564551.1; AtABF3, NP_567949.1), Catharanthus roseus (CrABF1, AF329450_1), Populus suaveolens (PsABF2, ABF29696.1), Populus trichocarpa (PtABF, XP_002313119.1), Ricinus communis (RcABF, XP_002518757.1), Solanum lycopersicum (SlABF, AAS20434.1) and Populus trichocarpa (PtABF2, ABN58425.1). Black and gray shaded backgrounds indicated that the amino acids were identical or similar to PtrABF, respectively. The basic region and the three heptad leucine repeats, two important bZIP signatures, are shown by double line and arrows, respectively. C1, C2, C3 and C4 are conserved regions containing residues of serine ('•') and threonine ('').
