Gα signaling pathway as well as the global regulator LaeA were demonstrated to positively regulate the biosynthesis of chaetoglobosin A (ChA), a promising biotic pesticide produced by Chaetomium globosum. Recently, the regulatory function of Zn2Cys6 binuclear finger transcription factor CgcheR that lies within the ChA biosynthesis gene cluster has been confirmed. However, CgcheR was not merely a pathway specific regulator. In this study, we showed that the homologs gene of CgcheR (designated as Cgtf1) regulate ChA biosynthesis and sporulation in C. globosum NK102. More importantly, RNA-seq profiling demonstrated that 1,388 genes were significant differentially expressed as Cgtf1 deleted. Among them, a putative C2H2 transcription factor, named Cgtf6, showed the highest gene expression variation in zinc-binding proteins encoding genes as Cgtf1 deleted. qRT-PCR analysis confirmed that expression of Cgtf6 was significantly reduced in CgTF1 null mutants. Whereas, deletion of Cgtf6 resulted in the transcriptional activation and consequent increase in the expression of ChA biosynthesis gene cluster and ChA production in C. globosum. These data suggested that CgTF6 probably acted as an end product feedback effector, and interacted with CgTF1 to maintain a tolerable concentration of ChA for cell survival.

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering the morphological, physiological, and biochemical processes of the plants. It is estimated that about 50% + of the productivity of several crops is limited due to various types of abiotic stresses either presence alone or in combination (s). However, there are two ways plants can survive against these abiotic stresses; a) through management practices and b) through adaptive mechanisms to tolerate plants. These adaptive mechanisms of tolerant plants are mostly linked to their signalling transduction pathway, triggering the action of plant transcription factors and controlling the expression of various stress-regulated genes. In recent times, several studies found that Zn-finger motifs have a significant function during abiotic stress response in plants. In the first report, a wide range of Zn-binding motifs has been recognized and termed Zn-fingers. Since the zinc finger motifs regulate the function of stress-responsive genes. The Zn-finger was first reported as a repeated Zn-binding motif, comprising conserved cysteine (Cys) and histidine (His) ligands, in Xenopus laevis oocytes as a transcription factor (TF) IIIA (or TFIIIA). In the proteins where Zn2+ is mainly attached to amino acid residues and thus espousing a tetrahedral coordination geometry. The physical nature of Zn-proteins, defining the attraction of Zn-proteins for Zn2+, is crucial for having an in-depth knowledge of how a Zn2+ facilitates their characteristic function and how proteins control its mobility (intra and intercellular) as well as cellular availability. The current review summarized the concept, importance and mechanisms of Zn-finger motifs during abiotic stress response in plants.

“…Furthermore, DkERF10, DkERF9 and DkERF19 were themselves regulated by upstream DkERF20/21, DkMYB10, and DkERF18/19, respectively [10,12]. Apart from these TFs, WRKYs [6], NACs [14], ZFs [15] and other family transcription factors have also been reported to be associated with persimmon fruit deastringency caused by high CO 2 treatment. Dof genes are plant specific transcription factors [16].…”

High CO2 treatment is a widely used deastringency technology that causes the accumulation of acetaldehyde which precipitates the astringent soluble tannins from persimmon fruit, making them more attractive to consumers. The identification of DkADH1 and DkPDC2 (the key genes for acetaldehyde accumulation) and their regulators (e.g., ERFs), has significantly advanced our understanding of the fruit deastringency mechanism, but other TFs are also involved in the high CO2 response. Here, 32 DkDofs genes were identified from ‘Gongcheng-shuishi’ persimmon, with nine of them shown to differentially respond to high CO2 treatment. Dual luciferase assay indicated that DkDof3 and DkDof6 could repress the promoters of DkADH1 and DkPDC2, respectively. EMSA assay showed that DkDof3 and DkDof6 physically interacted with probes containing T/AAAAG elements from the DkADH1 promoter, whereas they failed to recognize similar elements from the DkPDC2 promoter. The expression of DkDof3 and DkDof6 was also found to be repressed in different persimmon cultivars in response to high CO2 treatment. It is proposed that DkDof3 and DkDof6 were involved in fruit deastringency by regulating the expression of DkADH1 and DkPDC2 in different persimmon cultivars.
