TaFDL2-1A interacts with TabZIP8-7A protein to cope with drought stress via the abscisic acid signaling pathway

Genome-Wide Identification and Analysis of bZIP Gene Family and Resistance of TaABI5 (TabZIP96) under Freezing Stress in Wheat (Triticum aestivum)

“…TabZIP15 can improve salt tolerance of wheat [29]. TaFDL2 interacts with TabZIP8 protein to jointly regulate ABA signaling in response to drought stress [30]. The osmotic stress tolerance of wheat was closely related to the expression level and trend of TaDREB1-D [31].…”

TaFDL2‐1A confers drought stress tolerance by promoting ABA biosynthesis, ABA responses, and ROS scavenging in transgenic wheat

“…Studies have shown that high transcript levels of wheat bZIP transcription factors regulate the rearrangement of carbohydrates (Luang et al., 2018), osmotic adjustment capacity (Li et al., 2016), stomatal closure (Xu et al., 2014), and the expression of ABA‐inducible genes (Kobayashi, Maeta, Terashima, Kawaura, et al., 2008; Kobayashi, Maeta, Terashima, & Takumi, 2008; Wang et al., 2016; Zhang, Zhang, et al., 2015) to contribute to drought stress tolerance via the ABA signaling pathway. Similarly, a previous study demonstrated that the wheat bZIP transcription factor gene TaFDL2‐1A contributes to drought stress resistance via regulating ABA signaling in Arabidopsis (Wang et al., 2021). However, it is unknown whether TaFDL2‐1A increases the transcript levels of ABA‐inducible genes in transgenic wheat.…”

“…Interestingly, the expression of OsLG3 , OsADR3 , and TaASR1‐D can be induced by exogenous abscisic acid (ABA) application, which suggests that the antioxidant system might be connected to the ABA signaling pathway (Hu et al., 2013; Li et al., 2021; Qiu et al., 2021; Xiong et al., 2018). Similarly, we demonstrated that the expression of TaFD‐Like2‐1A ( TaFDL2‐1A ) decreased damage due to ROS under drought conditions via the ABA signaling pathway (Wang et al., 2021), but little is known about the mechanisms underlying the improved ROS scavenging capacity.…”

“…The PP2Cs combine competitively with PYR/PYL/RCARs following the increase in ABA levels under stress conditions, thereby freeing and activating SnRK2s (Ma et al., 2009; Park et al., 2009). The ABA‐activated SnRK2s then phosphorylate many downstream families of transcription factors, for instance, basic leucine zipper (bZIP), WRKY, and NAC transcription factors, and these transcription factors activate the expression of ABA‐inducible genes to transmit the ABA signal (Chen et al., 2021; Kim et al., 2004; Shang et al., 2020; Wang et al., 2021; Yan et al., 2021). Studies have shown that high transcript levels of wheat bZIP transcription factors regulate the rearrangement of carbohydrates (Luang et al., 2018), osmotic adjustment capacity (Li et al., 2016), stomatal closure (Xu et al., 2014), and the expression of ABA‐inducible genes (Kobayashi, Maeta, Terashima, Kawaura, et al., 2008; Kobayashi, Maeta, Terashima, & Takumi, 2008; Wang et al., 2016; Zhang, Zhang, et al., 2015) to contribute to drought stress tolerance via the ABA signaling pathway.…”

“…Therefore, greater sensitivity to ABA and increased drought resistance might be related to the accumulation of ABA (Cohen et al., 2015). Previously, we overexpressed the bZIP transcription factor gene TaFDL2‐1A and found that this results in ABA hypersensitivity and enhanced drought stress resistance (Wang et al., 2021), but the function of TaFDL2‐1A in ABA biosynthesis requires further clarification.…”
