“…An increasing number of studies have shown that WRKY TFs can positively respond to the tolerance of plants to high temperatures. For example, CaWRKY40 in pepper participates in the response of plants to high-temperature stress [ 89 ], and the overexpression of CaWRKY40 reduces the sensitivity of tobacco to high-temperature treatment, whereas the loss of this TF reduces this tolerance [ 90 ]. Similar results were found for CaWRKY40 and GhWRKY39 , expressed in upland cotton [ 91 , 92 ].…”

Plant growth and development are closely related to the environment, and high-temperature stress is an important environmental factor that affects these processes. WRKY transcription factors (TFs) play important roles in plant responses to high-temperature stress. WRKY TFs can bind to the W-box cis-acting elements of target gene promoters, thereby regulating the expression of multiple types of target genes and participating in multiple signaling pathways in plants. A number of studies have shown the important biological functions and working mechanisms of WRKY TFs in plant responses to high temperature. However, there are few reviews that summarize the research progress on this topic. To fully understand the role of WRKY TFs in the response to high temperature, this paper reviews the structure and regulatory mechanism of WRKY TFs, as well as the related signaling pathways that regulate plant growth under high-temperature stress, which have been described in recent years, and this paper provides references for the further exploration of the molecular mechanisms underlying plant tolerance to high temperature.

“…A previous study indicated that AtWRKY52 (group III member) in Arabidopsis thaliana confers resistance to the bacterial soil-borne pathogen R. solanacearum (Deslandes et al, 1998 , 2002 ). CaWRKY28, CaWRKY30 (group III member), CaWRKY40, CaWRKY41 (group III member), and CaWRKY58 in pepper regulated the defense response to R. solanacearum in plants (Wang et al, 2012 ; Muhammad et al, 2018 ; Dang et al, 2019 ; Hussain et al, 2021 ; Liu et al, 2021 ; Yang et al, 2021 ). Overexpression of sugarcane class III WRKY5 increased bacterial wilt resistance (Wang et al, 2020 ).…”

As one of the most important and largest transcription factors, WRKY plays a critical role in plant disease resistance. However, little is known regarding the functions of the WRKY family in cultivated peanuts (Arachis hypogaea L.). In this study, a total of 174 WRKY genes (AhWRKY) were identified from the genome of cultivated peanuts. Phylogenetic analysis revealed that AhWRKY proteins could be divided into four groups, including 35 (20.12%) in group I, 107 (61.49%) in group II, 31 (17.82%) in group III, and 1 (0.57%) in group IV. This division is further supported by the conserved motif compositions and intron/exon structures. All AhWRKY genes were unevenly located on all 20 chromosomes, among which 132 pairs of fragment duplication and seven pairs of tandem duplications existed. Eighteen miRNAs were found to be targeting 50 AhWRKY genes. Most AhWRKY genes from some groups showed tissue-specific expression. AhWRKY46, AhWRKY94, AhWRKY156, AhWRKY68, AhWRKY41, AhWRKY128, AhWRKY104, AhWRKY19, AhWRKY62, AhWRKY155, AhWRKY170, AhWRKY78, AhWRKY34, AhWRKY12, AhWRKY95, and AhWRKY76 were upregulated in ganhua18 and kainong313 genotypes after Ralstonia solanacearum infection. Ten AhWRKY genes (AhWRKY34, AhWRKY76, AhWRKY78, AhWRKY120, AhWRKY153, AhWRKY155, AhWRKY159, AhWRKY160, AhWRKY161, and AhWRKY162) from group III displayed different expression patterns in R. solanacearum sensitive and resistant peanut genotypes infected with the R. solanacearum. Two AhWRKY genes (AhWRKY76 and AhWRKY77) from group III obtained the LRR domain. AhWRKY77 downregulated in both genotypes; AhWRKY76 showed lower-higher expression in ganhua18 and higher expression in kainong313. Both AhWRKY76 and AhWRKY77 are targeted by ahy-miR3512, which may have an important function in peanut disease resistance. This study identified candidate WRKY genes with possible roles in peanut resistance against R. solanacearum infection. These findings not only contribute to our understanding of the novel role of WRKY family genes but also provide valuable information for disease resistance in A. hypogaea.

“…The cis-elements analysis of the promoter sequence of CmGLP2-5 (2000 bp) found that its promoter sequence contained a large number of MYB-binding sites and W-box ( Figure 4 ). Among them, W-box is considered to be the potential binding site of the WRKY transcription factor [ 31 , 32 , 33 ]. We cloned a fragment P in the CmGLP2-5 promoter, which contains a W-box and three MYB-binding sites ( Figure 7 A).…”

Germin-like protein (GLP) participates in plant growth and development and plays an important role in plant stress. In the present study, 22 CmGLPs belonging to five classes were identified in the melon genome. Each member of the CmGLPs family contains a typical Cupin_1 domain. We conducted a genome-wide analysis of the melon GLP gene family characterization. CmGLPs were randomly distributed in the melon chromosomes, with the largest number on chromosome 8, having eight family members. Gene duplication events drive the evolution and expansion of the melon GLP gene family. Based on the phylogenetic tree analysis of GLP proteins in melon, rice, Arabidopsis, and cucumber, it was found that the GLP gene families of different species have diverged in evolution. Based on qRT-PCR results, all members of the CmGLP gene family could be expressed in different tissues of melon. Most CmGLP genes were up-regulated after low-temperature stress. The relative expression of CmGLP2-5 increased by 157.13 times at 48 h after low-temperature treatment. This finding suggests that the CmGLP2-5 might play an important role in low-temperature stress in melon. Furthermore, quantitative dual LUC assays indicated that CmMYB23 and CmWRKY33 can bind the promoter fragment of the CmGLP2-5. These results were helpful in understanding the functional succession and evolution of the melon GLP gene family and further revealed the response of CmGLPs to low-temperature stress in melon.
