TabZIP60 is involved in the regulation of ABA synthesis-mediated salt tolerance through interacting with TaCDPK30 in wheat (Triticum aestivum L.)

The 14-3-3 Protein BdGF14a Increases the Transcriptional Regulation Activity of BdbZIP62 to Confer Drought and Salt Resistance in Tobacco

“…ABF2 was involved in the abiotic stress response by regulating the transcription of downstream ABA-responsive genes by binding to the ABRE element [ 23 , 24 , 40 , 41 ]. BdGF14a was reported to interact with three BdABRE/ABF TFs [ 32 ], and it could regulate the expression of NtNCED1 , a potential target of ABF2 ( Figure 6 I); thus, yeast two-hybrid (Y2H) and yeast one-hybrid (Y1H) experiments were performed to detect the interaction of NtABF2 with the BdGF14a/ABRE cis -element.…”

“…Moreover, the overexpression of MdGRF11 improved drought tolerance by altering the transcription of marker genes related to ABA signaling [ 53 ]. OsGF14f positively mediated the ABA-based responses induced by drought via interaction with OsbZIP23, a notable ABRE/ABF TF, to activate the transcriptional regulation of downstream target genes by binding to the ABRE elements of their promoters [ 23 , 24 , 40 , 41 ]. Hence, the transcription of the ABA-related genes NtDREB3 , NtERD10C/D , NtTobLTP1 , NtLTP1 , and NtLEA5 , which functioned in coping with abiotic stress, was selected to analyze the molecular mechanisms more thoroughly [ 59 , 60 , 61 ], which were remarkably increased in the OE tobaccos under salt and drought ( Figure 6 A–F).…”

“…In addition to NtNCED1 , a crucial ABA biosynthesis-related gene, NtABF2 , encoding a critical transcriptional regulator of ABA-based signaling, was also highly expressed ( Figure 6 G,I) [ 62 , 63 ]. TabZIP60 directly binds to the promoter of TaNCED2 at the ABRE core sequences to respond positively to salt-induced stress with a higher ABA content [ 40 ]. OsbZIP23 promoted the expression of OsNCED4 , a vital gene related to ABA biosynthesis, by combining with the ABRE element of its promoter to mediate the feedback regulation of the ABA response, and the “OsbZIP23-OsGF14f” interaction enhanced this transcriptional activity while coping with osmotic-state-related stress [ 24 ].…”

Calcium signaling facilitates chilling- and GA- induced dormancy release in tree peony

“…Calcium signaling modulating GA and ABA pathways has been documented in several plants and physiological processes ( Kim et al., 2010 ; Ho et al., 2013 ; Zhang et al., 2023a ). In soybean, low concentrations of CaCl 2 inhibit GA biosynthesis and impede radical protrusion, whereas high concentrations of CaCl 2 suppress ABA biosynthesis ( Wang et al., 2021 ).…”

“…We screened several PsCDPKs involved in the regulation of dormancy release. In wheat, TaCDPK30 interacts with TabZIP60 to regulate salt tolerance via modulating ABA synthesis ( Zhang et al., 2023a ). We speculated that PsCDPKs might function through the phosphorylation of downstream proteins to convey the calcium signal.…”
