“…The plant AT-rich sequences and zinc-binding (PLATZ) proteins belong to a novel class of plant specific zinc finger transcription factor, with two distant-conserved domains ( Nagano et al., 2001 ). PLATZ genes play important roles in several biological processes, including plant growth and development ( Gonzalez-Morales et al., 2016 ; Kim et al., 2018 ; Zenda, 2019 ; Jun et al., 2020 ; Liu et al., 2020 ; Dong et al., 2021 ). In rice, GL6 as a rice grain length QTL, positively affected grain length and yield by regulating cell division ( Wang et al., 2019 ).…”

“…ORESARA15 (ORE15), a PLATZ-type transcriptional activator in Arabidopsis , positively regulates the expression of leaf size related- and senescence related-genes ( Kim et al., 2018 ). Furthermore, PLATZ proteins in plants are also involved in response to abiotic stresses ( Zhang et al., 2018 ; Blair et al., 2019 ; Zenda, 2019 ; Liu et al., 2020 ; Dong et al., 2021 ). For example, the PLATZ family member AIN1 participated in the regulation of ROS homeostasis in Arabidopsis after ABA treatment ( Dong et al., 2021 ).…”

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.

“…Those secondary metabolites are necessary for ABA biosynthesis ( Xie et al., 2022 ) ( Figure 6 ). The plant hormone abscisic acid (ABA) is the key active regulator functioning in plant stress response and tolerance through the regulation of stress-responsive genes or stomatal movement and modulating ROS homeostasis ( Smyk-Randall and Brown, 1987 ; Fujita et al., 2011 ; Nakashima and Yamaguchi-Shinozaki, 2013 ; Dong et al., 2021 ). Transcriptome and metabolome integrative analyses linked DEGs with the Diffexp metabolites.…”

Drought stress usually causes huge economic losses for tobacco industries. Drought stress exhibits multifaceted impacts on tobacco systems through inducing changes at different levels, such as physiological and chemical changes, changes of gene transcription and metabolic changes. Understanding how plants respond and adapt to drought stress helps generate engineered plants with enhanced drought resistance. In this study, we conducted multiple time point-related physiological, biochemical,transcriptomic and metabolic assays using K326 and its derived mutant 28 (M28) with contrasting drought tolerance. Through integrative analyses of transcriptome and metabolome,we observed dramatic changes of gene expression and metabolic profiles between M28 and K326 before and after drought treatment. we found that some of DEGs function as key enzymes responsible for ABA biosynthesis and metabolic pathway, thereby mitigating impairment of drought stress through ABA signaling dependent pathways. Four DEGs were involved in nitrogen metabolism, leading to synthesis of glutamate (Glu) starting from NO−3 /NO−2 that serves as an indicator for stress responses. Importantly, through regulatory network analyses, we detected several drought induced TFs that regulate expression of genes responsible for ABA biosynthesis through network, indicating direct and indirect involvement of TFs in drought responses in tobacco. Thus, our study sheds some mechanistic insights into how plant responding to drought stress through transcriptomic and metabolic changes in tobacco. It also provides some key TF or non-TF gene candidates for engineering manipulation for breeding new tobacco varieties with enhanced drought tolerance.

“…GbPLATZ expression differed significantly between tissues, indicating that the family may have a variety of functions. Indeed, AtPLATZ1 ( Dong et al, 2021 ) induces expression of ABA in roots and controls the growth of taproots; AtPLATZ7 ( Yamada et al, 2020 ) controls the size of the root meristem through ROS signals; AtPLATZ3 ( Jun et al, 2020 ) promotes leaf growth by promoting the rate and duration of cell proliferation in leaves. In seeds, SG6/GL6 ( Wang et al, 2019 ; Zhou and Xue, 2020 ) of rice and ZmPLATZ2/12 ( Li et al, 2017 , 2021 ) of maize have also been reported to play a regulatory role.…”

“…The pea PLATZ1 non-specifically binds to A/T-rich sequences and represses the transcription of the pea GTPase pra2 and plastocyanin petE genes ( Yukio et al, 2001 ). AtPLATZ1 (ABA-INDUCED expression 1) is involved in ABA-inhibited primary root elongation via modulation of ROS homeostasis in Arabidopsis ( Dong et al, 2021 ). AtPLATZ2 negatively regulates salt tolerance in Arabidopsis seedlings by directly suppressing the expression of the CBL4/SOS3 and CBL10/SCaBP8 genes.…”

Plant AT-rich protein and zinc-binding protein (PLATZ) is a class of plant-specific zinc-dependent DNA-binding protein that binds to A/T-rich DNA sequences. PLATZ plays an important role in seed development, water tolerance, and cell proliferation in early plant growth. In this study, 11 GbPLATZs were identified from the ginkgo genome with complete PLATZ-conserved domains, which represents a smaller number compared with angiosperms. Multi-species phylogenetic analysis showed that PLATZ genes were conserved in seed plants, and the 11 members were represented by four groups, among which groups I and II were closely related. Analysis of gene structures, sequence module characteristics, and expression patterns showed that GbPLATZs were similar within and differed between groups. RNA-seq and qRT-PCR results showed that GbPLATZs had distinct expression patterns. Most genes were associated with seed development, among which six genes were highly related. Subcellular localization experiments showed that six GbPLATZ proteins related to seed development were localized in the nucleus, suggesting that they might function as traditional transcription factors. This study provides a basis for understanding the structural differentiation, evolutionary characteristics, expression profile, and potential functions of PLATZ transcription factors in Ginkgo biloba.
