Many plant species respond to unfavorable high ambient temperatures by adjusting their vegetative body plan to facilitate cooling. This process is known as thermomorphogenesis and is induced by the phytohormone auxin. Here, we demonstrate that the chromatin-modifying enzyme HISTONE DEACETYLASE 9 (HDA9) mediates thermomorphogenesis but does not interfere with hypocotyl elongation during shade avoidance. HDA9 is stabilized in response to high temperature and mediates histone deacetylation at the < ...[more]

Project description:Ambient temperature affects plant growth and even minor changes can substantially impact crop yields. The underlying mechanisms of temperature perception and response are just beginning to emerge. Chromatin remodeling, via the eviction of the histone variant H2A.Z containing nucleosomes, is a critical component of thermal response in plants. However, the role of histone modifications remains unknown. Here, through a forward genetic screen, we identify POWERDRESS (PWR), a SANT-domain containing protein known to interact with HISTONE DEACETYLASE 9 (HDA9), as a novel factor required for thermomorphogenesis in Arabidopsis thaliana. We show that mutations in PWR impede thermomorphogenesis, exemplified by attenuated warm temperature-induced hypocotyl/petiole elongation and early flowering. We show that inhibitors of histone deacetylases diminish temperature-induced hypocotyl elongation, which demonstrates a requirement for histone deacetylation in thermomorphogenesis. We also show that elevated temperature is associated with deacetylation of H3K9 at the +1 nucleosomes of PHYTOCHROME INTERACTING FACTOR4 (PIF4) and YUCCA8 (YUC8), and that PWR is required for this response. There is global misregulation of genes in pwr mutants at elevated temperatures. Meta-analysis revealed that genes that are misregulated in pwr mutants display a significant overlap with genes that are H2A.Z-enriched in their gene bodies, and with genes that are differentially expressed in mutants of the components of the SWR1 complex that deposits H2A.Z. Our findings thus uncover a role for PWR in facilitating thermomorphogenesis and suggest a potential link between histone deacetylation and H2A.Z nucleosome dynamics in plants.

Project description:Natural genetic variation in Arabidopsis thaliana exists for many traits and often reflects acclimation to local environments. Studying natural variation has proven valuable in the characterization of phenotypic traits and, in particular, in identifying genetic factors controlling these traits. It has been previously shown that chromatin compaction changes during development and biotic stress. To gain more insight into the genetic control of chromatin compaction, we investigated the nuclear phenotype of 21 selected Arabidopsis accessions from different geographic origins and habitats. We show natural variation in chromatin compaction and demonstrate a positive correlation with latitude of geographic origin. The level of compaction appeared to be dependent on light intensity. A novel approach, combining Quantitative Trait Locus (QTL) mapping and microscopic examination, pointed at PHYTOCHROME-B (PHYB) and HISTONE DEACETYLASE-6 (HDA6) as positive regulators of light-controlled chromatin compaction. Indeed, mutant analyses demonstrate that both factors affect global chromatin organization. HDA6, in addition, strongly promotes the light-mediated compaction of the Nucleolar Organizing Regions (NORs). The accession Cape Verde Islands-0 (Cvi-0), which shows sequence polymorphism in the PHYB gene and in the HDA6 promotor, resembles the hda6 mutant in having reduced chromatin compaction and decreased methylation levels of DNA and histone H3K9 at the NORs. We provide evidence that chromatin organization is controlled by light intensity. We propose that chromatin plasticity is associated with acclimation of Arabidopsis to its environment. The polymorphic alleles such as PHYB and HDA6 control this process.

Project description:Harnessing the plant microbiome has the potential to improve agricultural yields and protect plants against pathogens and/or abiotic stresses, while also relieving economic and environmental costs of crop production. While previous studies have gained valuable insights into the underlying genetics facilitating plant-fungal interactions, these have largely been skewed towards certain fungal clades (e.g. arbuscular mycorrhizal fungi). Several different phyla of fungi have been shown to positively impact plant growth rates, including Mortierellaceae fungi. However, the extent of the plant growth promotion (PGP) phenotype(s), their underlying mechanism(s), and the impact of bacterial endosymbionts on fungal-plant interactions remain poorly understood for Mortierellaceae. In this study, we focused on the symbiosis between soil fungus Linnemannia elongata (Mortierellaceae) and Arabidopsis thaliana (Brassicaceae), as both organisms have high-quality reference genomes and transcriptomes available, and their lifestyles and growth requirements are conducive to research conditions. Further, L. elongata can host bacterial endosymbionts related to Mollicutes and Burkholderia. The role of these endobacteria on facilitating fungal-plant associations, including potentially further promoting plant growth, remains completely unexplored. We measured Arabidopsis aerial growth at early and late life stages, seed production, and used mRNA sequencing to characterize differentially expressed plant genes in response to fungal inoculation with and without bacterial endosymbionts. We found that L. elongata improved aerial plant growth, seed mass and altered the plant transcriptome, including the upregulation of genes involved in plant hormones and "response to oxidative stress", "defense response to bacterium", and "defense response to fungus". Furthermore, the expression of genes in certain phytohormone biosynthetic pathways were found to be modified in plants treated with L. elongata. Notably, the presence of Mollicutes- or Burkholderia-related endosymbionts in Linnemannia did not impact the expression of genes in Arabidopsis or overall growth rates. Together, these results indicate that beneficial plant growth promotion and seed mass impacts of L. elongata on Arabidopsis are likely driven by plant hormone and defense transcription responses after plant-fungal contact, and that plant phenotypic and transcriptional responses are independent of whether the fungal symbiont is colonized by Mollicutes or Burkholderia-related endohyphal bacteria.

Project description: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.

Project description:Dynamic trimethylation of histone H3 at Lys27 (H3K27me3) affects gene expression and controls plant development and environmental responses. In Arabidopsis thaliana, RELATIVE OF EARLY FLOWERING 6 (REF6)/JUMONJI DOMAIN-CONTAINING PROTEIN 12 demethylates H3K27me3 by recognizing a specific DNA motif. However, little is known about how REF6 activates target gene expression after recognition, especially in environmental responses. In response to warm ambient temperature, plants undergo thermomorphogenesis, which involves accelerated growth, early flowering and changes in morphology. Here we show that REF6 regulates thermomorphogenesis and cooperates with the transcription factor PHYTOCHROME INTERACTING FACTOR 4 to synergistically activate thermoresponsive genes under warm ambient temperature. The ref6 loss-of-function mutants exhibited attenuated hypocotyl elongation at warm temperature, partially due to downregulation of GIBBERELLIN 20-OXIDASE 2 and BASIC HELIX-LOOP-HELIX 87. REF6 enzymatic activity is necessary for warm ambient temperature responses. Together, our results provide direct evidence of an epigenetic modifier and a transcription factor working together to respond to the environment.

Project description:We report POWERDRESS (PWR), a SANT domain containing protein known to facilitate the deacetylation of lysine rich residues of histone H3 by HISTONE DEACETYLASE 9 (HDA9), to play key role in temperature induced growth in Arabidopsis thaliana. Mutations in PWR showed severe attenuation in high temperature associated phenotypes viz., temperature-induced hypocotyl elongation, petiole elongation and early flowering. The study involved analysing the impact of the loss of PWR on the transcriptome in response to changes in ambient temperature. About one hundred 6 day old seedlings of wild type (Col-0) and pwr-2 mutant (in Col-0 background) were grown at 23 °C in short days (SD) photoperiod in growth chambers (GR-36, Percival Scientific, Canada). Half of the samples were then shifted to 27°C under short day photoperiod. Total RNA was extracted from whole seedlings grown at 23 °C and 27°C after two hours. Two biological replicates were used for Col-0 and pwr-2 samples. RNA was extracted using Isolate II RNA plant kit (Bioline Pty Ltd, Australia). RNA-Seq libraries were generated on Illumina HiSeqTM 2000 platform using paired-end sequencing of 90 bp in length at BGI-Shenzen (Beijing Genomics Institute). Gene expression analysis was performed using DESeq2 (v1.14.1) differential expression analysis pipeline.

Project description:Sequence similarity and profile searching tools were used to analyze the genome sequences of Arabidopsis thaliana, Saccharomyces cerevisiae, Schizosaccharomyces pombe, Caenorhabditis elegans and Drosophila melanogaster for genes encoding three families of histone deacetylase (HDAC) proteins and three families of histone acetyltransferase (HAT) proteins. Plants, animals and fungi were found to have a single member of each of three subfamilies of the GNAT family of HATs, suggesting conservation of these functions. However, major differences were found with respect to sizes of gene families and multi-domain protein structures within other families of HATs and HDACs, indicating substantial evolutionary diversification. Phylogenetic analysis identified a new class of HDACs within the RPD3/HDA1 family that is represented only in plants and animals. A similar analysis of the plant-specific HD2 family of HDACs suggests a duplication event early in dicot evolution, followed by further diversification in the lineage leading to Arabidopsis. Of three major classes of SIR2-type HDACs that are found in animals, fungi have representatives only in one class, whereas plants have representatives only in the other two. Plants possess five CREB-binding protein (CBP)-type HATs compared with one to two in animals and none in fungi. Domain and phylogenetic analyses of the CBP family proteins showed that this family has evolved three distinct types of CBPs in plants. The domain architecture of CBP and TAF(II)250 families of HATs show significant differences between plants and animals, most notably with respect to bromodomain occurrence and their number. Bromodomain-containing proteins in Arabidopsis differ strikingly from animal bromodomain proteins with respect to the numbers of bromodomains and the other types of domains that are present. The substantial diversification of HATs and HDACs that has occurred since the divergence of plants, animals and fungi suggests a surprising degree of evolutionary plasticity and functional diversification in these core chromatin components.

Project description:Histone acetylation plays a pivotal role in plant growth and development, and is regulated by the antagonistic relationship between histone acetyltransferase (HAT) and histone deacetylase (HDAC). We previously revealed that some HDAC inhibitors confer high-salinity stress tolerance in plants. In this study, we identified two HDAC inhibitors, namely Ky-9 and Ky-72, which enhanced the high-salinity stress tolerance of Arabidopsis thaliana. Ky-9 and Ky-72 are structurally similar chlamydocin analogs. However, the in vitro inhibitory activity of Ky-9 against mammalian HDAC is greater than that of Ky-72. A western blot indicated that Ky-9 and Ky-72 increased the acetylation levels of histone H3, suggesting they exhibit HDAC inhibitory activities in plants. We conducted a transcriptomic analysis to investigate how Ky-9 and Ky-72 enhance high-salinity stress tolerance. Although Ky-9 upregulated the expression of more genes than Ky-72, similar gene expression patterns were induced by both HDAC inhibitors. Additionally, the expression of high-salinity stress tolerance-related genes, such as anthocyanin-related genes and a small peptide-encoding gene, increased by Ky-9 and Ky-72. These data suggest that slight structural differences in chemical side chain between HDAC inhibitors can alter inhibitory effect on HDAC protein leading to influence gene expression, thereby enhancing high-salinity stress tolerance in different extent.

Project description:Piriformospora indica is a root-colonizing fungus, which interacts with a variety of plants including Arabidopsis thaliana. This interaction has been considered as mutualistic leading to growth promotion of the host. So far, only indolic glucosinolates and phytohormones have been identified as key players. In a comprehensive non-targeted metabolite profiling study, we analyzed Arabidopsis thaliana's roots, root exudates, and leaves of inoculated and non-inoculated plants by ultra performance liquid chromatography/electrospray ionization quadrupole-time-of-flight mass spectrometry (UPLC/(ESI)-QTOFMS) and gas chromatography/electron ionization quadrupole mass spectrometry (GC/EI-QMS), and identified further biomarkers. Among them, the concentration of nucleosides, dipeptides, oligolignols, and glucosinolate degradation products was affected in the exudates. In the root profiles, nearly all metabolite levels increased upon co-cultivation, like carbohydrates, organic acids, amino acids, glucosinolates, oligolignols, and flavonoids. In the leaf profiles, we detected by far less significant changes. We only observed an increased concentration of organic acids, carbohydrates, ascorbate, glucosinolates and hydroxycinnamic acids, and a decreased concentration of nitrogen-rich amino acids in inoculated plants. These findings contribute to the understanding of symbiotic interactions between plant roots and fungi of the order of Sebacinales and are a valid source for follow-up mechanistic studies, because these symbioses are particular and clearly different from interactions of roots with mycorrhizal fungi or dark septate endophytes.

Project description:Auxin is one type of phytohormones that plays important roles in nearly all aspects of plant growth and developmental processes. The glycosylation of auxins is considered to be an essential mechanism to control the level of active auxins. Thus, the identification of auxin glycosyltransferases is of great significance for further understanding the auxin regulation. In this study, we biochemically screened the group L of Arabidopsis thaliana glycosyltransferase superfamily for enzymatic activity toward auxins. UGT74D1 was identified to be a novel auxin glycosyltransferase. Through HPLC and LC-MS analysis of reaction products in vitro by testing eight substrates including auxins and other compounds, we found that UGT74D1 had a strong glucosylating activity toward indole-3-butyric acid [IBA], indole-3-propionic acid [IPA], indole-3-acetic acid [IAA] and naphthaleneacetic acid [NAA], catalyzing them to form corresponding glucose esters. Biochemical characterization showed that this enzyme had a maximum activity in HEPES buffer at pH 6.0 and 37°C. In addition, the enzymatic activity analysis of crude protein and the IBA metabolite analysis from transgenic Arabidopsis plants overexpressing UGT74D1 gene were also carried out. Experimental results indicated that over-production of the UGT74D1 in plants indeed led to increased level of the glucose conjugate of IBA. Moreover, UGT74D1 overexpression lines displayed curling leaf phenotype, suggesting a physiological role of UGT74D1 in affecting the activity of auxins. Our current data provide a new target gene for further genetic studies to understand the auxin regulation by glycosylation in plants.
