“…The bZIP family transcription factor AcePosF21 in kiwifruit [ 46 ] mediates the regulation of AceGP3 expression and AsA biosynthesis, thereby reducing oxidative damage caused by cold stress. PhebZIP47 in moso bamboo [ 47 ] positively regulates drought tolerance in transgenic plants by regulating differentially expressed genes (DEGs), including genes in the drought tolerance regulatory pathway and ABA signaling pathway. It is evident that bZIP transcription factors regulate downstream related genes as well as the response to various stresses through hormonal signaling in most plants [ 44 , 46 ].…”

Background Basic leucine zipper (bZIP) proteins are important transcription factors in plants. To study the role of bZIP transcription factors in walnut explant browning, this study used bioinformatics software to analyze walnut bZIP gene family members, along with their transcript levels in different walnut tissues, to evaluate the transcriptional expression of this gene family during the primary culture of walnut explants and to reveal the mechanism of action of walnut bZIP genes in walnut explant browning. Results The results identified 65 JrbZIP genes in the walnut genome, which were divided into 8 subfamilies and distributed on 16 chromosomes. The results of transcriptome data analysis showed that there were significant differences in the expression of four genes, namely, JrbZIP55, JrbZIP70, JrbZIP72, and JrbZIP88, under both vermiculite and agar culture conditions. There were multiple hormone (salicylic acid, abscisic acid, auxin, and gibberellin) signaling and regulatory elements that are responsive to stress (low temperature, stress, and defense) located in the promoter regions of JrbZIP55, JrbZIP70, JrbZIP72, and JrbZIP88. The walnut JrbZIP55 protein and Arabidopsis bZIP42 protein are highly homologous, and the proteins interacting with Arabidopsis bZIP42 include the AT2G19940 oxidoreductases, which act on aldehyde or oxygen-containing donors. Conclusion It is speculated that JrbZIP55 may participate in the regulation of browning in walnut explants.

“…Thus, efficient water transport capacity was the basis for bamboo growth. Many TFs of moso bamboo have been reported to be involved in response to stress, such as PeTCP10, PhebZIP47, and PhePLATZ1 playing positive regulatory roles in drought resistance (Liu et al ., 2020; K. Zhang et al ., 2022; Lan et al ., 2023). Recent evidence has proposed a novel hypothesis regarding the mechanisms of nonstructural carbohydrate and water balance during the rapid growth of bamboo shoots, with the involvement of aquaporins (Sun et al ., 2018).…”

Summary Water plays crucial roles in expeditious growth and osmotic stress of bamboo. Nevertheless, the molecular mechanism of water transport remains unclear. In this study, an aquaporin gene, PeTIP4‐3, was identified through a joint analysis of root pressure and transcriptomic data in moso bamboo (Phyllostachys edulis). PeTIP4‐3 was highly expressed in shoots, especially in the vascular bundle sheath cells. Overexpression of PeTIP4‐3 could increase drought and salt tolerance in transgenic yeast and rice. A co‐expression pattern of PeSAPK4, PeMYB99 and PeTIP4‐3 was revealed by WGCNA. PeMYB99 exhibited an ability to independently bind to and activate PeTIP4‐3, which augmented tolerance to drought and salt stress. PeSAPK4 could interact with and phosphorylate PeMYB99 in vivo and in vitro, wherein they synergistically accelerated PeTIP4‐3 transcription. Overexpression of PeMYB99 and PeSAPK4 also conferred drought and salt tolerance in transgenic rice. Further ABA treatment analysis indicated that PeSAPK4 enhanced water transport in response to stress via ABA signaling. Collectively, an ABA‐mediated cascade of PeSAPK4‐PeMYB99‐PeTIP4‐3 is proposed, which governs water transport in moso bamboo.

“…Similarly, TabZIP15 can also improve salt tolerance in Triticum aestivum ( Bi et al., 2021 ). Overexpression of Phyllostachys edulis PhebZIP47 in A. thaliana and Oryza sativa can increase the drought resistance of plants at the adult stages ( Lan et al., 2023 ). In transgenic Artemisia annua overexpressing AabZIP9 , the biosynthetic accumulation of artemisinin, dihydroartemisinic acid, and artemisinic acid was significantly increased ( Shen et al., 2019 ).…”

The Basic Leucine Zipper (bZIP) transcription factors (TFs) family is among of the largest and most diverse gene families found in plant species, and members of the bZIP TFs family perform important functions in plant developmental processes and stress response. To date, bZIP genes in Platycodon grandiflorus have not been characterized. In this work, a number of 47 PgbZIP genes were identified from the genome of P. grandiflorus, divided into 11 subfamilies. The distribution of these PgbZIP genes on the chromosome and gene replication events were analyzed. The motif, gene structure, cis-elements, and collinearity relationships of the PgbZIP genes were simultaneously analyzed. In addition, gene expression pattern analysis identified ten candidate genes involved in the developmental process of different tissue parts of P. grandiflorus. Among them, Four genes (PgbZIP5, PgbZIP21, PgbZIP25 and PgbZIP28) responded to drought and salt stress, which may have potential biological roles in P. grandiflorus development under salt and drought stress. Four hub genes (PgbZIP13, PgbZIP30, PgbZIP32 and PgbZIP45) mined in correlation network analysis, suggesting that these PgbZIP genes may form a regulatory network with other transcription factors to participate in regulating the growth and development of P. grandiflorus. This study provides new insights regarding the understanding of the comprehensive characterization of the PgbZIP TFs for further exploration of the functions of growth and developmental regulation in P. grandiflorus and the mechanisms for coping with abiotic stress response.
