“…In potato, StWRKY8 positively regulated the production of benzylisoquinoline alkaloids (BIAs) through increasing the transcript levels of TyDC, NCS, and COR-2 genes. BIAs as antimicrobial agents and cell wall enforcement agents were validated to eventually forbid the pathogen colonization in the late blight infestation [68]. Moreover, the maize TF ZmWRKY79 regulates the biosynthesis of phytoalexins in response to various stress conditions.…”

Plants are adapted to sense numerous stress stimuli and mount efficient defense responses by directing intricate signaling pathways. They respond to undesirable circumstances to produce stress-inducible phytochemicals that play indispensable roles in plant immunity. Extensive studies have been made to elucidate the underpinnings of defensive molecular mechanisms in various plant species. Transcriptional factors (TFs) are involved in plant defense regulations through acting as mediators by perceiving stress signals and directing downstream defense gene expression. The cross interactions of TFs and stress signaling crosstalk are decisive in determining accumulation of defense metabolites. Here, we collected the major TFs that are efficient in stress responses through regulating secondary metabolism for the direct cessation of stress factors. We focused on six major TF families including AP2/ERF, WRKY, bHLH, bZIP, MYB, and NAC. This review is the compilation of studies where researches were conducted to explore the roles of TFs in stress responses and the contribution of secondary metabolites in combating stress influences. Modulation of these TFs at transcriptional and post-transcriptional levels can facilitate molecular breeding and genetic improvement of crop plants regarding stress sensitivity and response through production of defensive compounds.

“…Indeed, the expression of the TYDC gene has been shown to be higher in disease-resistant plants than in susceptible plants. 73 In one case, the TYDC gene from parsley was introduced into potatoes to catalyze the metabolism of tyrosine, this increased the tyramine content in the cell wall and effectively improved the disease resistance of the potatoes. 74 Similarly, introducing the poppy TYDC gene into rapeseed significantly improved the binding of tyramine to the cell wall and reduced the digestibility of cells.…”

Dopamine (3-hydroxytyramine or 3,4-dihydroxyphenethylamine) has many functions in animals, but also shows several other functions in plants. Since the discovery of dopamine in plants in 1968, many studies have provided insight into physiological and biochemical functions, and stress responses of this molecule. In this review, we describe the biosynthesis of dopamine, as well as its role in plant growth and development. In addition, endogenous or exogenously applied dopamine improved the tolerance against several abiotic stresses, such as drought, salt, and nutrient stress. There are also several studies that dopamine contributes to the plant immune response against plant disease. Dopamine affects the expression of many abiotic stresses related genes, which highlights its role as a multi-regulatory molecule and can coordinate many aspects of plant development. Our review emphasized the effects of dopamine against environmental stresses along with future research directions, which will help improve the yield of eco-friendly crops and ensure food security.

“…To the authors' best knowledge, no expression data are available on ScWRKYs and SchWRKYs; by contrast, StWRKYs have previously received attention. Among them, only Shahzad et al 71 and Yogendra et al 72 found StWRKY010 (PGSC0003DMP400029302) and StWRKY020 (PGSC0003DMP400028763) to be active in P. infestans-potato interaction. Consistently with these data, our results indicated that the same genes increased their expression after BABA treatment, known to Scientific RepoRtS | (2020) 10:7196 | https://doi.org/10.1038/s41598-020-63823-w www.nature.com/scientificreports www.nature.com/scientificreports/ confer protection against several biotic threats.…”

Wild potatoes, as dynamic resource adapted to various environmental conditions, represent a powerful and informative reservoir of genes useful for breeding efforts. WRKY transcription factors (TFs) are encoded by one of the largest families in plants and are involved in several biological processes such as growth and development, signal transduction, and plant defence against stress. In this study, 79 and 84 genes encoding putative WRKY TFs have been identified in two wild potato relatives, Solanum commersonii and S. chacoense. Phylogenetic analysis of WRKY proteins divided ScWRKYs and SchWRKYs into three Groups and seven subGroups. Structural and phylogenetic comparative analyses suggested an interspecific variability of WRKYs. Analysis of gene expression profiles in different tissues and under various stresses allowed to select ScWRKY045 as a good candidate in woundingresponse, ScWRKY055 as a bacterial infection triggered WRKY and ScWRKY023 as a multiple stressresponsive WRKY gene. Those WRKYs were further studied through interactome analysis allowing the identification of potential co-expression relationships between ScWRKYs/SchWRKYs and genes of various pathways. Overall, this study enabled the discrimination of WRKY genes that could be considered as potential candidates in both breeding programs and functional studies.Plants experience environmental constrains and pathogen attacks during their life. Being sessile organisms, their survival depends on the ability to properly and promptly reprogram cellular networks. Several and different classes of transcription factors (TFs) work as "master regulators" and "selector genes", being able to control processes that specify cell types and developmental patterning and modulate specific pathways. Among them, WRKY factors are drawing a great deal of interest in the scientific community due to their ability to simultaneously cope with multiple stresses 1,2 . They are notorious for coordinating signals in plant immunity response against several pathogens and pest attacks 3,4 . More recently, it has been confirmed that WRKYs also base defence mechanism to abiotic stresses and play a key role in cross-talk pathway networks between plant response and development 5,6 . Their involvement into multiple stress response and in plant growth regulation is evidenced by their W-box specific DNA binding 7,8 . Besides, WRKY binds sugar responsive elements and, very recently, it has been demonstrated that they activate sugar responsive genes through an epigenetic mechanism of control 9 . The systematic classification of components of the WRKY family is well organized. It is based on the WRKY binding domain (WD) characteristics along with those of the Zinc Finger (ZF) motif, which is typically present downstream the WD. WD consists of 60 amino acids structured as four-stranded β-sheets able to enter the major groove of B-form DNA. The highly conserved motif is "WRKYGQK". According to the number of WDs and the type of zinc finger motif, WRKY proteins can be classified into three Groups,...
