Project description:The aim of this study was to analyze the impact of autotetraploidy on gene expression in Arabidopsis thaliana by comparing diploid versus tetraploid transcriptomes. In particular, this included the comparison of the transcriptome of different tetraploid A. thaliana ecotypes (Col-0 vs. Ler-0). The study was extended to address further aspects. One was the comparison of the transcriptomes in subsequent generations. This intended to obtain information on the genome wide stability of autotetraploid gene expression. Another line of work compared the transcriptomes of different diploid vs. tetraploid tissues. This aimed to investigate whether particular gene groups are specifically affected during the development of A. thaliana autotetraploids.

Project description:The increasing ambient temperature significantly impacts plant growth, development, and reproduction. Uncovering the temperature-regulating mechanisms in plants is of high importance, not only for boosting our plant biology knowledge but also for assisting plant breeders in improving plant resilience to these stress conditions. Numerous studies on the molecular mechanisms by which plants regulate temperature responses revealed that plants employ distinct transcription factors to regulate thermomorphogenesis specific to each tissue type. A significant discovery in this field was the identification of PHYTOCHROME-INTERACTING FACTORs (PIFs) as key regulators of thermomorphogenesis during vegetative growth. PIF4, a regulator of auxin-mediated signaling pathways, is crucial in controlling high-temperature responses. In this study, we screened the temperature responses of the wild type and several PhyB-PIF4 pathway Arabidopsis mutant lines in combined and integrative phenotyping platforms for root in soil, shoot, inflorescence, and seed. We demonstrated that high ambient temperature differentially impacts vegetative and reproductive organs through this pathway. Suppression of the PhyB-PIF4 components mimics the response to a high ambient temperature in wild-type plants. We also identified correlative responses to high ambient temperature between shoot and root tissues. This integrative and automated phenotyping was complemented by monitoring the changes in transcript levels in reproductive organs. Transcriptomic profiling of the pistils from plants grown under high ambient temperature identified key elements that may provide clues to the molecular mechanisms behind temperature-induced reduced fertilization rate, such as a downregulation of auxin metabolism, upregulation of genes involved auxin signalling, miRNA156 and miRN160 pathways, pollen tube attractants.

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.
