Abstract: DREB1 of the AP2/ERF superfamily plays a key role in the regulation of plant response to low temperatures. In this study, a novel DREB1/CBF transcription factor, PnDREB1, was isolated from Iceland poppy (Papaver nudicaule), a plant adaptive to low temperature environments. It is homologous to the known DREB1s of Arabidopsis and other plant species. It also shares similar 3D structure, and conserved and functionally important motifs with DREB1s of Arabidopsis. The phylogenetic analysis indicated that the AP2 do… Show more

“…The expressions of CBF genes in plants are associated with not only abiotic stresses but also hormones. PnDREB1 in Papaver nudicaule is involved in both GA and abiotic stresses pathways [ 61 ]. Furthermore, SwDREB1 from sweet potato participates in the ABA-independent pathway [ 62 ].…”

“…This TF family is associated with a few other pleiotropic roles, like regulating stress tolerance via expression of genes involved in abiotic stress response, disease resistance and ethylene/jasmonic acid/salicylic acid response (Cui et al, 2016; Guo et al, 2016). Based on the number of AP2/ERF DNA binding domains they possess, the AP2/ERF family is further classified into four subfamilies, namely ERF, DREB (one AP2/ERF domain); AP2 (two AP2/ERF domains) and RAV (one AP2 and an additional B3 DNA binding domain; Licausi et al, 2013; Guo et al, 2016; Huang Z. et al, 2016). The ERF subfamily in Arabidopsis is regulated either via a phytohormone dependent (like Ethylene, JA, ABA, auxin, cytokinin and SA; Guo and Ecker, 2004; Arora, 2005; Cheng et al, 2013; Dey and Vlot, 2015) or independent manner ( via Ethylene Insensitive or EIN genes, stress like wounding, etc., Guo and Ecker, 2004; Arora, 2005; Dey and Vlot, 2015).…”
