“…In tomato, WRKY8 plays a regulatory role in pathogen defense responses as well as in drought and salt stress responses [ 21 ]. The AhWRKY75 gene conferred salt stress tolerance in transgenic peanut plants by improving the efficiency of the ROS scavenging and photosynthesis under stress treatments [ 22 ]. Understanding the function and evolution of WRKY transcription factors will help to identify common connections in complex signaling pathways, to promote improvements in agricultural crop yield and quality [ 14 ].…”

The WRKY transcription factors are unique regulatory proteins in plants, which are important in the stress responses of plants. In this study, 113 WRKY genes were identified from the apple genome GDDH13 and a comprehensive analysis was performed, including chromosome mapping, and phylogenetic, motif and collinearity analysis. MdWRKYs are expressed in different tissues, such as seeds, flowers, stems and leaves. We analyzed seven WRKY proteins in different groups and found that all of them were localized in the nucleus. Among the 113 MdWRKYs, MdWRKY70L was induced by both drought and salt stresses. Overexpression of it in transgenic tobacco plants conferred enhanced stress tolerance to drought and salt. The malondialdehyde content and relative electrolyte leakage values were lower, while the chlorophyll content was higher in transgenic plants than in the wild-type under stressed conditions. In conclusion, this study identified the WRKY members in the apple genome GDDH13, and revealed the function of MdWRKY70L in the response to drought and salt stresses.

“…Numerous studies have indicated the crucial regulatory roles of WRKY transcription factors in plant growth and development, physiological and biochemistry processes, biotic and abiotic stress response [ 13 , 14 , 15 , 16 ]. For instance, overexpression of the transcription factor TaWRKY2 enhances drought stress tolerance and increase grain yield in transgenic wheat ( Triticum aestivum L.) [ 17 ]; while overexpression of OsWRKY29 represses seed dormancy by directly downregulating the expression of OsABF1 and OsVP1 in rice ( Oryza sativa L.) [ 18 ].…”

WRKY transcription factors constitute one of the largest gene families in plants and are involved in many biological processes, including growth and development, physiological metabolism, and the stress response. In earlier studies, the WRKY gene family of proteins has been extensively studied and analyzed in many plant species. However, information on WRKY transcription factors in Acer truncatum has not been reported. In this study, we conducted genome-wide identification and analysis of the WRKY gene family in A. truncatum, 54 WRKY genes were unevenly located on all 13 chromosomes of A. truncatum, the highest number was found in chromosomes 5. Phylogenetic relationships, gene structure, and conserved motif identification were constructed, and the results affirmed 54 AtruWRKY genes were divided into nine subgroup groups. Tissue species analysis of AtruWRKY genes revealed which were differently exhibited upregulation in flower, leaf, root, seed and stem, and the upregulation number were 23, 14, 34, 18, and 8, respectively. In addition, the WRKY genes expression in leaf under cold stress showed that more genes were significantly expressed under 0, 6 and 12 h cold stress. The results of this study provide a new insight the regulatory function of WRKY genes under abiotic and biotic stresses.

“…Studies also showed that TaWRKY1 and TaWRKY33 in wheat (He et al, 2016), and ZmWRKY40 in maize (Wang L. et al, 2018) could enhance drought tolerance of Arabidopsis plants. Furthermore, overexpression of HbWRKY82 enhanced drought and salt tolerance and reduced sensitivity to ABA in transgenic Arabidopsis thaliana (Kang et al, 2021), and overexpression of AhWRKY75 enhanced salt tolerance in transgenic peanut (Zhu et al, 2021).…”

Dendrobium catenatum has become a rare and endangered medicinal plant due to habitat loss in China. As one of the most important and largest transcription factors, WRKY plays a critical role in response to abiotic stresses in plants. However, little is known regarding the functions of the WRKY family in D. catenatum. In this study, a total of 62 WRKY genes were identified from the D. catenatum genome. Phylogenetic analysis revealed that DcWRKY proteins could be divided into three groups, a division supported by the conserved motif compositions and intron/exon structures. DcWRKY gene expression and specific responses under drought, heat, cold and salt stresses were analyzed through RNA-seq data and RT-qPCR assay. The results showed that these genes had tissue-specificity and displayed different expression patterns in response to abiotic stresses. The expression levels of DcWRKY22, DcWRKY36 and DcWRKY45 were up-regulated by drought stress. Meanwhile, DcWRKY22 was highly induced by heat in roots, and DcWRKY45 was significantly induced by cold stress in leaves. Furthermore, DcWRKY27 in roots and DcWRKY58 in leaves were extremely induced under salt treatment. Finally, we found that all the five genes may function in ABA- and SA-dependent manners. This study identified candidate WRKY genes with possible roles in abiotic stress and these findings not only contribute to our understanding of WRKY family genes, but also provide valuable information for stress resistance development in D. catenatum.
