Project description:This study aimed to characterise the genome-wide PIF7-mediated responses of Arabidopsis thaliana seedlings to long photoperiods with a warm 27°C midday in comparison to long photoperiods at constant 17°C. Transcriptomic responses were observed in Col-0 wild-type and pif7-1 loss-of-function mutants investigate the potential contribution of the transcription factor PIF7 to the warm temperature response under the described conditions. In parallel, ChIP-seq of a PIF7-MYC-expressing line under the same conditions was employed to investigate global DNA binding changes of PIF7 in response to a change in temperature.

Project description:The goal of this study was to compare the transcriptional profile (RNA-seq) of Arabidopsis thaliana Columbia-0 ecotype seedlings that were treated with two different light (white light or shade) and temperature (20ºC or 28ºC) conditions.
Project description:Plant roots located in the upper soil layers are prone to experience high temperatures. To gain insight into the effect of high temperature on root development and functioning, we exposed five-day-old Arabidopsis thaliana seedlings grown on agar plates to 30 °C for 48 hours, and compared the gene expression profile in the root tip with that from seedlings that remained at 22 °C.
Project description:Next-generation sequencing (NGS) has been used to study the differential gene expression in Arabidopsis green seedlings under warm temperature. The goal of this study is to investigate how ethylene signaling and epigenetic modification are involved in transcriptional regulation in response to warm temperature.
Project description:To understand expression phenotypes in Arabidopsis thaliana at high temperature, a set of the Multiparent Advanced Generation Inter-Cross (MAGIC) recombinant inbred lines were grown under long day conditions (16 hours light: 8 hours dark) at 20˚C and then shifted to 30˚C for 48 hours. RNA was collected at the 4th true leaf stage, and RNA-seq data was generated using the Illumina method. The MAGIC lines included are largely a subset of lines for which comparable RNA-seq data was collected at a constant 20˚C (allowing the same genotypes to be compared at 20˚C and after the high temperature shift at approximately the same developmental stage and under otherwise the same growth conditions). The read data for the analogous low temperature study can be found under GEO submission GSE94107.

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.
