“…ZATs appear to have a general role in mediating abiotic stress tolerance (e.g. cold, drought) (Yin et al, 2017), while ZAT14 integrates phosphate starvation responses (Devaiah et al, 2007). Interestingly, WRKY18 showed a clear cell type-specific pattern.…”

Root pathogens are a major threat in global crop production and protection strategies are required to sustainably enhance the efficiency of root immunity. Our understanding of root immunity is still limited relative to our knowledge of immune responses in leaves. In an effort to reveal the organisation of immunity in roots, we undertook a cell type-specific transcriptome analysis to identify gene networks activated in epidermis, cortex and pericycle cells of Arabidopsis roots upon treatment with two immunity elicitors, the bacterial microbe-associated molecular pattern flagellin, and the endogenous damageassociated molecular pattern Pep1. Our analyses revealed that both elicitors induced immunity gene networks in a cell type-specific manner. Interestingly, both elicitors did not alter cell identity-determining gene networks. Using sophisticated paired motif promoter analyses, we identified key transcription factor pairs involved in the regulation of cell typespecific immunity networks. In addition, our data show that cell identity networks integrate with cell immunity networks to activate cell type-specific immune response according to the functional capabilities of each cell type.All rights reserved.

“…Among them, C2H2 ZFP is a eukaryotic transcription factor, which contains 1-4 zinc finger structures, and, in plants, it has a highly conserved QALGGH motif, which plays an important role in abiotic stress [23]. Since the first C2H2 ZFP gene EPF1 was isolated from petunia [24], more C2H2 ZFP family genes have been found in plants and widely reported to be involved in responses to biotic and abiotic stresses [25]. In Arabidopsis, constitutive expression of AtZAT7 or AtZAT10 improved salt tolerance [25,26].…”

Aluminum (Al) toxicity limits plant growth and has a major impact on the agricultural productivity in acidic soils. The zinc-finger protein (ZFP) family plays multiple roles in plant development and abiotic stresses. Although previous reports have confirmed the function of these genes, their transcriptional mechanisms in wild soybean (Glycine soja) are unclear. In this study, GsGIS3 was isolated from Al-tolerant wild soybean gene expression profiles to be functionally characterized in Arabidopsis. Laser confocal microscopic observations demonstrated that GsGIS3 is a nuclear protein, containing one C2H2 zinc-finger structure. Our results show that the expression of GsGIS3 was of a much higher level in the stem than in the leaf and root and was upregulated under AlCl 3 , NaCl or GA3 treatment. Compared to the control, overexpression of GsGIS3 in Arabidopsis improved Al tolerance in transgenic lines with more root growth, higher proline and lower Malondialdehyde (MDA) accumulation under concentrations of AlCl 3 . Analysis of hematoxylin staining indicated that GsGIS3 enhanced the resistance of transgenic plants to Al toxicity by reducing Al accumulation in Arabidopsis roots. Moreover, GsGIS3 expression in Arabidopsis enhanced the expression of Al-tolerance-related genes. Taken together, our findings indicate that GsGIS3, as a C2H2 ZFP, may enhance tolerance to Al toxicity through positive regulation of Al-tolerance-related genes.

“…Overexpression of other ZFPs also results in an increase in tolerance to the stress that induces them. [7][8][9][10][11][12] Shi et al demonstrated that OEZat6 lines enhance tolerance to bacterial infection, freezing, drought and salinity stress, while artificial microRNA of Zat6 reduce tolerance. 11 Yin et al found that OEZat18 lines were more tolerant to drought stress while T-DNA mutant Zat18 lines were less tolerant.…”

Tobacco hornworm (Manduca sexta, THW) is a voracious pest of tomato and potato. StZFP2 is a Q-type C2H2 zinc finger transcription factor (TF) that is induced upon wounding and infestation. Previous work has shown that Q-type C2H2 TFs are involved in stress responses and when over expressed, can enhance protection against drought, salinity or pathogen infection. Twelve transgenic lines (S1-S12) were tested that over-express StZFP2. Feeding S6 or S8 to THW significantly lowered larval weight (21-37%) as well as increased expression of StPIN2 in comparison to untransformed Kennebec. The increase in StPIN2, a classic marker for insect defense in potato, is consistent with the decreases in larval weight gain.
