“…Leucine zipper is an extremely conserved protein as it contains a motif of five heptads of amino acids placed sequentially with a leucine at seventh spot. Leucine is highly stabilizing as compared to other amino acids (Vincentz et al, 2001). The leucine zippers switch the homo-and heteroconnotation of bZIP members.…”

Basic leucine zipper protein refers to a grand transcriptional factor family of all eukaryotes that is involved in various developmental and stress responses like flower development, plant height, maturation of seeds, biotic and abiotic stress signaling. About 127 bZIPs in Arabidopsis, 70 in cotton (Gossypium hirsutum), 266 in soybean (Glycine max), 47 in tobacco (Nicotiana tabacum), 70 in tomato (Solanum lycopersicum), 140 in rice, 102 in wheat and 218 in maize have been discovered. In this review, the classification of bZIP is according to the binding specificities of bZIPs as well as their role in transcription.

“…Intermediate filament coiled coils were based on Strelkov et al (2003). Viral coat proteins, laminins, fibrinogens, heat shock factors and flagellins were based on Wolf et al (1997) and Singh et al (1999) and the bZIPs according to Newman and Keating (2003), Vincentz et al (2001) and Fassler et al (2002). Dynein heavy chains were annotated according to Gee et al (1997) and by inspection, and kinesin heavy chains after Thormählen et al (1998), Morii et al (1997) and inspection.…”

“…Transcription factors (TFs) are regulators of gene expression in biological systems. TFs interact with other proteins or DNA in the promoter region of their target genes to regulate their expression under specific conditions [ 11 ]. TFs are said to operate either alone or in complex with other molecules to induce or suppress the recruitment of the basal transcriptional machinery to specific genes [ 12 , 13 , 14 , 15 ].…”

The intrinsic defense mechanisms of plants toward pathogenic bacteria have been widely investigated for years and are still at the center of interest in plant biosciences research. This study investigated the role of the AtbZIP62 gene encoding a transcription factor (TF) in the basal defense and systemic acquired resistance in Arabidopsis using the reverse genetics approach. To achieve that, the atbzip62 mutant line (lacking the AtbZIP62 gene) was challenged with Pseudomonas syringae pv. tomato (Pst DC3000) inoculated by infiltration into Arabidopsis leaves at the rosette stage. The results indicated that atbzip62 plants showed an enhanced resistance phenotype toward Pst DC3000 vir over time compared to Col-0 and the susceptible disease controls, atgsnor1-3 and atsid2. In addition, the transcript accumulation of pathogenesis-related genes, AtPR1 and AtPR2, increased significantly in atbzip62 over time (0–72 h post-inoculation, hpi) compared to that of atgsnor1-3 and atsid2 (susceptible lines), with AtPR1 prevailing over AtPR2. When coupled with the recorded pathogen growth (expressed as a colony-forming unit, CFU mL−1), the induction of PR genes, associated with the salicylic acid (SA) defense signaling, in part explained the observed enhanced resistance of atbzip62 mutant plants in response to Pst DC3000 vir. Furthermore, when Pst DC3000 avrB was inoculated, the expression of AtPR1 was upregulated in the systemic leaves of Col-0, while that of AtPR2 remained at a basal level in Col-0. Moreover, the expression of AtAZI (a systemic acquired resistance -related) gene was significantly upregulated at all time points (0–24 h post-inoculation, hpi) in atbzip62 compared to Col-0 and atgsnor1-3 and atsid2. Under the same conditions, AtG3DPH exhibited a high transcript accumulation level 48 hpi in the atbzip62 background. Therefore, all data put together suggest that AtPR1 and AtPR2 coupled with AtAZI and AtG3DPH, with AtAZI prevailing over AtG3DPH, would contribute to the recorded enhanced resistance phenotype of the atbzip62 mutant line against Pst DC3000. Thus, the AtbZIP62 TF is proposed as a negative regulator of basal defense and systemic acquired resistance in plants under Pst DC3000 infection.
