Project description:Analysis of the transcriptome of dry hda9-1 mutant seeds with those of Col wild-type seeds, using Affymetrix GeneChip Arabidopsis ATH1 Genome Array. The hda9-1 mutant has reduced primary seed dormancy. We used microarrays to dissect which genes are differentially expressed in the hda9-1 mutant to study the mechanisms how HDA9 affects seed dormancy and germination

Project description:We use metabolite profiles of the model plant Arabidopsis thaliana measured on an UPLC-ESI/QqTOF-MS to evaluate uni- and multivariate statistical analysis of redundant features in compound spectra. Comparison was performed between the wild-type Col-0 and the 90.32 mutant. The mutant is a transposon based activation tagged A. th. line from the TAMARA population Schneider et al. [2005]. This particular mutant has an over-expression of the AT5G55880 - AT5G55890 genetic region with unknown function.

Project description:The role of non-CG methylation in seed development and dormancy remains unknown. There are four genes in charge of non-CG methylation in Arabidopsis: drm1, drm2, cmt2 and cmt3. The majority of non-CG methylation in vegetative tissues, leaf, is gone in homozygous ddcc mutant line (Hume et al., 2014). To uncover the possible role of non-CG DNA methylation in seed development and dormancy, we characterized the methylome of ddcc mutant in Arabidopsis postmature-green-stage seed and dry seed using Illumina sequencing. Meanwhile, vegetative tissue, leaves from 3 week plant with ddcc mutant and from wild-type, and postmature-green-stage seed and dry seed from wild-type plant were used as control.

Project description:Histone acetylation is involved in the regulation of gene expression in plants and eukaryotes. Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl groups from histones, which is associated with the repression of gene expression. To study the role of histone acetylation in the regulation of gene expression during seed germination, trichostatin A (TSA), a specific inhibitor of histone deacetylase, was used to treat imbibing Arabidopsis thaliana seeds. GeneChip arrays were used to show that TSA induces up-regulation of 45 genes and down-regulation of 27 genes during seed germination. Eight TSA-up-regulated genes were selected for further analysis - RAB18, RD29B, ATEM1, HSP70 and four late embryogenesis abundant protein genes (LEA). A gene expression time course shows that these eight genes are expressed at high levels in the dry seed and repressed upon seed imbibition at an exponential rate. In the presence of TSA, the onset of repression of the eight genes is not affected but the final level of repressed expression is elevated. Chromatin immunoprecipitation and HDAC assays show that there is a transient histone deacetylation event during seed germination at one day after imbibition, which serves as a key developmental signal that affects the repression of the eight genes.

Project description:We compared the proteome of dry as well as germinating seeds of Arabidopsis thaliana wild type Col-0 with the respective proteomes from an umk2 (AT4G25280) frameshift mutant.
Germinating seeds were incubated for 48 hours in 1/2-MS medium in Petri dishes at 4 degree Celsius followed by 24 hours of a phytochamber under long-day conditions.
Protein extraction, digestion by SP3 workflow, and LC-IMS-MS/MS analysis as described in https://doi.org/10.1038/s41477-022-01308-6.

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.
