HDACs MADS-domain protein interaction: a case study of HDA15 and XAL1 in Arabidopsis thaliana. PLANT SIGNALING & BEHAVIOR 2024; 19:2353536.

Abstract
Cellular behavior, cell differentiation and ontogenetic development in eukaryotes result from complex interactions between epigenetic and classic molecular genetic mechanisms, with many of these interactions still to be elucidated. Histone deacetylase enzymes (HDACs) promote the interaction of histones with DNA by compacting the nucleosome, thus causing transcriptional repression. MADS-domain transcription factors are highly conserved in eukaryotes and participate in controlling diverse developmental processes in animals and plants, as well as regulating stress responses in plants. In this work, we focused on finding out putative interactions of Arabidopsis thaliana HDACs and MADS-domain proteins using an evolutionary perspective combined with bioinformatics analyses and testing the more promising predicted interactions through classic molecular biology tools. Through bioinformatic analyses, we found similarities between HDACs proteins from different organisms, which allowed us to predict a putative protein-protein interaction between the Arabidopsis thaliana deacetylase HDA15 and the MADS-domain protein XAANTAL1 (XAL1). The results of two-hybrid and Bimolecular Fluorescence Complementation analysis demonstrated in vitro and in vivo HDA15-XAL1 interaction in the nucleus. Likely, this interaction might regulate developmental processes in plants as is the case for this type of interaction in animals.

Abstract
Histone deacetylases (HDACs), responsible for the removal of acetyl groups from histone tails, are important epigenetic factors. They play a critical role in the regulation of gene expression and are significant in the context of plant growth and development. The Rpd3/Hda1 family of HDACs is reported to regulate key biological processes in plants, such as stress response, seed, embryonic, and floral development. Here, we characterized Arabidopsis thaliana HDA7, a Class I, Rpd3/Hda1 family HDAC. SAXS and AUC results show that the recombinantly expressed and purified histone deacetylase domain of AtHDA7 exists as a monomer in solution. Further, the crystal structure showed AtHDA7 to fold into the typical α/β arginase fold, characteristic of Rpd3/Hda1 family HDACs. Sequence analysis revealed that the Asp and His residues of the catalytic 'XDXH' motif present in functional Rpd3/Hda1 family HDACs are mutated to Gly and Pro, respectively, in AtHDA7, suggesting that it might be catalytically inactive. The Asp and His residues are important for Zn2+-binding. Not surprisingly, the crystal structure did not have Zn2+ bound in the catalytic pocket, which is essential for the HDAC activity. Further, our in vitro activity assay revealed AtHDA7 to be inactive as an HDAC. A search in the sequence databases suggested that homologs of AtHDA7 are found exclusively in the Brassicaceae family to which Arabidopsis belongs. It is possible that HDA7 descended from HDA6 through whole genome duplication and triplication events during evolution, as suggested in a previous phylogenetic study.

Abstract
Histone deacetylases (HDACs) are important chromatin regulators essential for plant tolerance to adverse environments. In addition to histone deacetylation and epigenetic regulation, HDACs deacetylate non-histone proteins and thereby regulate multiple pathways. Like other post-translational modifications (PTMs), acetylation/deacetylation is a reversible switch regulating different cellular processes in plants. Here, by focusing on results obtained in arabidopsis (Arabidopsis thaliana) and rice plants, we analyze the different aspects of HDAC functions and the underlying regulatory mechanisms in modulating plant responses to stress. We hypothesize that, in addition to epigenetic regulation of gene expression, HDACs can also control plant tolerance to stress by regulating transcription, translation, and metabolic activities and possibly assembly-disassembly of stress granules (SGs) through lysine deacetylation of non-histone proteins.

Abstract
Post-translational modifications (PTMs) of proteins play important roles in the acclimation of plants to environmental stress. Lysine acetylation is a dynamic and reversible PTM, which can be removed by histone deacetylases. Here we investigated the role of lysine acetylation in the response of Arabidopsis leaves to 1 week of salt stress. A quantitative mass spectrometry analysis revealed an increase in lysine acetylation of several proteins from cytosol and plastids, which was accompanied by altered histone deacetylase activities in the salt-treated leaves. While activities of HDA14 and HDA15 were decreased upon salt stress, HDA5 showed a mild and HDA19 a strong increase in activity. Since HDA5 is a cytosolic-nuclear enzyme from the class II histone deacetylase family with yet unknown protein substrates, we performed a lysine acetylome analysis on hda5 mutants and characterized its substrate proteins. Next to histone H2B, the salt stress-responsive transcription factor GT2L and the dehydration-related protein ERD7 were identified as HDA5 substrates. In addition, in protein-protein interaction studies, HDA18 was discovered, among other interacting proteins, to work in a complex together with HDA5. Altogether, this study revealed the substrate proteins of HDA5 and identified new lysine acetylation sites which are hyperacetylated upon salt stress. The identification of specific histone deacetylase substrate proteins, apart from histones, will be important to unravel the acclimation response of Arabidopsis to salt stress and their role in plant physiology.

Abstract
Histone deacetylases (HDAs) regulate many aspects of plant development and responses to environmental changes. Previous studies have demonstrated that the Arabidopsis histone deacetylase HDA15 is a positive regulator in far-red (FR) light-mediated inhibition of hypocotyl elongation. Furthermore, HDA15 can be phosphorylated and its enzymatic activity is negatively regulated by phosphorylation. However, the kinases that can phosphorylate HDA15 are still unknown. Cyclin-dependent kinases (CDKs) are a large family of serine/threonine protein kinases and have been identified as major regulators of the cell cycle and transcription. In this study, we show that the cyclin-dependent kinase CDKC2 interacts with HDA15 both in vitro and in vivo. In vitro kinase assays show that CDKC2 phosphorylates HDA15. Genetic evidence suggests that HDA15 acts downstream of CDKC2 in hypocotyl elongation under FR light. Furthermore, HDA15 and CDKC2 function synergistically in the regulation of FR-mediated cell elongation. The expression of cell wall organization- and auxin signaling-related genes under FR light is increased in hda15 and cdkc2/hda15 mutants. Taken together, our study indicates that CDKC2 can phosphorylate HDA15 and plays an important role in FR light-regulated hypocotyl elongation.

Abstract
Histone deacetylases (HDAs) play an important role in transcriptional regulation of multiple biological processes. In this study, we investigated the function of HDA15 in abscisic acid (ABA) responses. We used immunopurification coupled with mass spectrometry-based proteomics to identify proteins interacting with HDA15 in Arabidopsis (Arabidopsis thaliana). HDA15 interacted with the core subunits of the MOS4-associated complex (MAC), MAC3A and MAC3B, with interaction between HDA15 and MAC3B enhanced by ABA. hda15 and mac3a/mac3b mutants were ABA-insensitive during seed germination and hyposensitive to salinity. RNA sequencing analysis demonstrated that HDA15 and MAC3A/MAC3B co-regulate ABA-responsive intron retention (IR). Furthermore, HDA15 reduced the histone acetylation level of genomic regions near ABA-responsive IR sites and the association of MAC3B with ABA-responsive pre-mRNA was dependent on HDA15. Our results indicate that HDA15 is involved in ABA responses by interacting with MAC3A/MAC3B to mediate splicing of introns.

Abstract
Leaf senescence is controlled by a complex regulatory network in which robustness is ensured by the activity of transcription factors and epigenetic regulators. However, how these coordinate the process of leaf senescence remains poorly understood. We found that WHIRLY1 interacts with Histone Deacetylase (HDA)15, a Reduced Potassium Dependence3 (RPD3)/HDA1-type HDA, by using green fluorescent protein-nanotrap-mass spectrum assays. The development-dependent interaction between WHIRLY1 and HDA15 was further confirmed by bimolecular fluorescence complementation assays and co-immunoprecipitation assays in Arabidopsis. Multi-omics genome-wide transcriptome and H3K9 acetylome enrichment analysis showed that HDA15 delays leaf senescence and flowering by repressing the expression of the positive regulators of leaf senescence and flowering, such as LOX2 and LARP1C, and reducing H3K9ac levels at these loci; WHIRLY1 and HDA15 co-target to the region near the transcription start site of a subset of nutrient recycling-related genes (e.g., Glutathione S-transferases 10, non-coding RNA, and photosystem II protein D1 synthesizer attenuator PDIL1-2), as well as WRKY53 and ELF4, and co-repress their expression by removing H3K9 acetylation. Our study revealed a key transcription regulatory node of nutrient recycling and senescence-associated genes involved in leaf senescence and flowering via the recruitment of HDA15 by the single-stranded DNA/RNA-binding protein WHIRLY1.

Abstract
Anthocyanin accumulation is a hallmark response to nitrogen (N) deficiency in Arabidopsis. Although the regulation of anthocyanin biosynthesis has been extensively studied, the roles of chromatin modification in this process are largely unknown. In this study we show that anthocyanin accumulation induced by N deficiency is modulated by HISTONE DEACETYLASE15 (HDA15) in Arabidopsis seedlings. The hda15-1 T-DNA insertion mutant accumulated more anthocyanins than the wild-type when the N supply was limited, and this was caused by up-regulation of anthocyanin biosynthetic and regulatory genes in the mutant. The up-regulated genes also had increased levels of histone acetylation in the mutant. The accumulation of anthocyanins induced by sucrose and methyl jasmonate, but not that induced by H2O2 and phosphate starvation, was also greater in the hda15-1 mutant. While sucrose increased histone acetylation in the hda15-1 mutant in genes in a similar manner to that caused by N deficiency, methyl jasmonate only enhanced histone acetylation in the genes involved in anthocyanin biosynthesis. Our results suggest that different stresses act through distinct regulatory modules to activate anthocyanin biosynthesis, and that HDA15-mediated histone modification modulates the expression of anthocyanin biosynthetic and regulatory genes to avoid overaccumulation in response to N deficiency and other stresses.

Abstract
Temperature is a key factor in determining plant growth and development, geographical distribution, and seasonal behavior. Plants accurately sense subtle changes in ambient temperature and alter their growth and development accordingly to improve their chances of survival and successful propagation. Thermomorphogenesis encompasses a variety of morphological changes that help plants acclimate to warm environmental temperatures. Revealing the molecular mechanism of thermomorphogenesis is important for breeding thermo-tolerant crops and ensuring food security under global climate change. Plant adaptation to elevated ambient temperature is regulated by multiple signaling pathways and epigenetic mechanisms such as histone modifications, histone variants, and non-coding RNAs. In this review, we summarize recent advances in the mechanism of epigenetic regulation during thermomorphogenesis with a focus on the model plant Arabidopsis thaliana and briefly discuss future prospects for this field.

Abstract
Zn2+-dependent histone deacetylases are widely distributed in archaea, bacteria, and eukaryotes. Through deacetylation of histones and other biomolecules, these enzymes regulate mammalian gene expression, microtubule stability, and polyamine metabolism. In plants, they play essential roles in development and stress response, but little is known about their biochemistry. We provide here a holistic revision of plant histone deacetylase (HDA) phylogeny and translate recent lessons from other organisms. HDA evolution correlates with a gain of structural ductility/disorder, as observed for other proteins. We also highlight two recently identified Brassicaceae-specific HDAs, as well as unprecedented key mutations that would affect the catalytic activity of individual HDAs. This revised phylogeny will contextualize future studies and illuminate research on plant development and adaptation.

Abstract
Comprehensive characterization of Gramineae HATs and HDACs reveals their conservation and variation. The recent WGD/SD gene pairs in the CBP and RPD/HDA1 gene family may confer specific adaptive evolutionary changes. Expression of OsHAT and OsHDAC genes provides a new vision in different aspects of development and response to diverse stress. The histone acetylase (HAT) and histone deacetylase (HDAC) have been proven to be tightly linked to play a crucial role in plant growth, development and response to abiotic stress by regulating histone acetylation levels. However, the evolutionary dynamics and functional differentiation of HATs and HDACs in Gramineae remain largely unclear. In the present study, we identified 37 HAT genes and 110 HDAC genes in seven Gramineae genomes by a detailed analysis. Phylogenetic trees of these HAT and HDAC proteins were constructed to illustrate evolutionary relationship in Gramineae. Gene structure, protein property and protein motif composition illustrated the conservation and variation of HATs and HDACs in Gramineae. Gene duplication analysis suggested that recent whole genome duplication (WGD)/segmental duplication (SD) events contributed to the diversification of the CBP and RPD3/HDA1 gene family in Gramineae. Furthermore, promoter cis-element prediction indicated that OsHATs and OsHDACs were likely functional proteins and involved in various signaling pathways. Expression analysis by RNA-seq data showed that all OsHAT and OsHDAC genes were expressed in different tissues or development stages, revealing that they were ubiquitously expressed. In addition, we found that their expression patterns were altered in response to cold, drought, salt, light, abscisic acid (ABA), and indole-3-acetic acid (IAA) treatments. These findings provide the basis for further identification of candidate OsHAT and OsHDAC genes that may be utilized in regulating growth and development and improving crop tolerance to abiotic stress.
