“…ZmNF-YA3 binds to the promoter of bHLH92 , FAMA , and MYC4 to improve drought tolerance in maize ( Su et al., 2018 ). Furthermore, GO and KEGG enrichment analysis results showed that multiple co-expression genes were enriched into plant hormone signaling transduction pathway, which is in line with the fact that plants cope with various environmental stresses via regulating hormone synthesis and hormone signal transduction ( Li et al., 2008 ; Xu et al., 2013 ; Zhang et al., 2022 ). Last but not least, a number of MdPLATZ genes were upregulated under ABA treatments in apple roots.…”

“…At present, more than fifty TFs families have been identified in plants. The zinc finger transcription factor is one of the largest TF families in plants, including ERF, PHD, PLATZ, ZFP, TZF, and WRKY ( Zhang et al., 2022 ). Previous studies have found that they were involved in various environmental stresses, especially drought stress ( Han et al., 2019 ; Sun et al., 2019 ).…”

Plant AT-rich sequences and zinc-binding proteins (PLATZ) play crucial roles in response to environmental stresses. Nevertheless, PLATZ gene family has not been systemically studied in Rosaceae species, such as in apple, pear, peach, or strawberry. In this study, a total of 134 PLATZ proteins were identified from nine Rosaceae genomes and were classified into seven phylogenetic groups. Subsequently, the chromosomal localization, duplication, and collinearity relationship for apple PLATZ genes were investigated, and segmental duplication is a major driving-force in the expansion of PLATZ in Malus. Expression profiles analysis showed that PLATZs had distinct expression patterns in different tissues, and multiple genes were significantly changed after drought and ABA treatments. Furthermore, the co-expression network combined with RNA-seq data showed that PLATZ might be involved in drought stress by regulating ABA signaling pathway. In summary, this study is the first in-depth and systematic identification of PLATZ gene family in Rosaceae species, especially for apple, and provided specific PLATZ gene resource for further functional research in response to abiotic stress.

“…Moreover, ABA can induce the expression of AIN1 in Arabidopsis, thereby affecting the elongation of the primary root [10]. PhePLATZ genes in moso bamboo were significantly regulated by GA, ABA, and MeJA treatments [41]. In the present study, hormone-responsive elements related to ABA, MeJA, SA, GA, and IAA were examined in the promoter region of FtPLATZ genes; however, their distribution across different FtPLATZ genes was diverse, which is similar to the findings of Fu et al in the identification of TaPLATZs [1].…”

Background Plant AT-rich sequence and zinc-binding (PLATZ) proteins belong to a novel class of plant-specific zinc-finger-dependent DNA-binding proteins that play essential roles in plant growth and development. Although the PLATZ gene family has been identified in several species, systematic identification and characterization of this gene family has not yet been carried out for Tartary buckwheat, which is an important medicinal and edible crop with high nutritional value. The recent completion of Tartary buckwheat genome sequencing has laid the foundation for this study. Results A total of 14 FtPLATZ proteins were identified in Tartary buckwheat and were classified into four phylogenetic groups. The gene structure and motif composition were similar within the same group, and evident distinctions among different groups were detected. Gene duplication, particularly segmental duplication, was the main driving force in the evolution of FtPLATZs. Synteny analysis revealed that Tartary buckwheat shares more orthologous PLATZ genes with dicotyledons, particularly soybean. In addition, the expression of FtPLATZs in different tissues and developmental stages of grains showed evident specificity and preference. FtPLATZ3 may be involved in the regulation of grain size, and FtPLATZ4 and FtPLATZ11 may participate in root development. Abundant and variable hormone-responsive cis-acting elements were distributed in the promoter regions of FtPLATZs, and almost all FtPLATZs were significantly regulated after exogenous hormone treatments, particularly methyl jasmonate treatment. Moreover, FtPLATZ6 was significantly upregulated under all exogenous hormone treatments, which may indicate that this gene plays a critical role in the hormone response of Tartary buckwheat. Conclusions This study lays a foundation for further exploration of the function of FtPLATZ proteins and their roles in the growth and development of Tartary buckwheat and contributes to the genetic improvement of Tartary buckwheat.

“…The transgenic Arabidopsis thaliana with GhPLATZ1 may promote seed germination and seedling formation under salt stress by increasing the GA and ethylene content and reducing the ABA content ( Han et al., 2022 ). It was found that PhePLATZ23 and PLATZ27 are highly responsive to cold stress and play an extremely important role in regulating bamboo’s response to external environmental stimuli ( Zhang et al., 2022 ). UVR8 mainly involves the perception and transduction of light signals, while the PLATZ transcription factor is more related to plant transcriptional regulation and stress response.…”

Low temperature and cold damage seriously hinder the growth, development, and morphogenesis of cotton seedlings. However, the response mechanism of cotton seedlings under cold stress still lacks research. In this study, transcriptome sequencing, gas exchange parameters, and rapid chlorophyll fluorescence parameters were analyzed in leaves of cold-tolerant upland cotton variety “ZM36” under different temperature stress [25°C (T25, CK), 15°C (T15), 10°C (T10), and 4°C (T4)]. The results showed that the net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), PSII potential maximum photochemical efficiency (Fv/Fm), and performance index (PIabs) of cotton leaves significantly decreased, and the intercellular CO2 concentration (Ci) and Fo/Fm significantly increased under cold stress. The transcriptome sequencing analysis showed that a total of 13,183 DEGs were involved in the response of cotton seedlings at each temperature point (T25, T15, T10, and T4), mainly involving five metabolic pathways—the phosphatidylinositol signaling system, photosynthesis, photosynthesis antenna protein, carbon fixation in photosynthetic organisms, and carotenoid synthesis. The 1,119 transcription factors were discovered among all the DEGs. These transcription factors involve 59 families, of which 15.8% of genes in the NAC family are upregulated. Through network regulatory analysis, the five candidate genes GhUVR8 (GH_A05G3668), GhPLATZ (GH_A09G2161), GhFAD4-1 (GH_A01G0758), GhNFYA1 (GH_A02G1336), and GhFAD4-2 (GH_D01G0766) were identified in response to cold stress. Furthermore, suppressing the expression level of GhPLATZ by virus-induced gene silencing led to the reduction of low temperature resistance, implying GhPLATZ as a positive regulator of low temperature tolerance. The findings of the study revealed a piece of the complex response mechanism of the cold-tolerant variety “ZM36” to different cold stresses and excavated key candidate genes for low temperature response, which provided support for accelerating the selection and breeding of cotton varieties with low temperature tolerance.
