Dynamics of mRNA fate during light stress and recovery: from transcription to stability and translation

Project description:The stability of mRNA is an important determinant of its abundance and, consequently, protein production. There has been extensive research on the pathways governing mRNA stability and translation, however, it is unclear the extent to which these processes are modulated by environmental conditions. We previously modelled rapid recovery gene down-regulation (RRGD) following light stress in Arabidopsis thaliana (Arabidopsis) using mathematical calculations to account for transcription in order to predict half-lives and led to the hypothesis of recovery-specific transcript destabilisation. Here, we test this hypothesis by quantifying changes in transcription, mRNA stability, and translation in leaves of mature Arabidopsis undergoing light stress and recovery and investigate processes regulating transcript abundance and fate. Compared to juvenile plants from prior work, here we find that stability is altered for a range of transcripts that encode proteins involved in post-transcriptional processes in mature leaves. We also observe transcript destabilisation during light stress, followed by re-stabilisation upon recovery. Alongside this, we observe fast transcriptional shut-off in recovery that, when paired with transcript destabilisation, promotes rapid down-regulation of stress-induced genes. Translation was dynamic over the course of light stress and recovery, with substantial transcript-specific increases in polysome loading observed during late stress independently of total mRNA abundance. Taken together, we provide evidence for the combinatorial regulation of transcription, mRNA stability, and translation that occurs during light stress and recovery.

Acute effects of light on alternative splicing in light-grown plants

Project description:We report the results of a genome-wide analysis of AS in Arabidopsis thaliana plants exposed to a 2h light pulse given in the middle of the night, a treatment that simulates the effects of early dawn or late dusk signals. This light affects the plant transcriptome at multiple regulatory layers, and that light regulation of mRNA levels of splicing regulatory factors is likely to mediate light effects on AS contributing to adjust plant physiological processes to the prevailing light environment. Arabidopsis seedlings of the Columbia ecotype were grown under 12 hr light/12 hr dark cycles for 9 days. On the 10th day, half of the plants were exposed to a two-hour pulse of white light given in the middle of the night (ZT18), while the other half were kept in darkness as controls. Both groups of plants were harvested at ZT 20 and light effects on mRNA levels and AS were analyzed through RNA-seq.

oxi1 transcriptome-Transcriptomic analysis on the effect of oxi1 mutation under high light.

Project description:cea13-01_oxi1 - oxi1 transcriptome - Transcriptomic analysis on the effect of oxi1 mutation under high light stress? - 5 weeks old mutannt (M) and wild type (WT) plants were exposed to high light and low temperature (1300-1350 µmol photons m-2s-1, 7°C/14°C day/night and 380ppm CO2) for 25 hours. ~100 mg fresh weight leaves were harvested, and total RNA prepared from them. For control experiments, leaves were harvested directly from the phytotron (No light stress). Three microarray comparisons were made: Mcontrol/WTcontrol, Mstress/WTstress and Mstress/Mcontrol . For each comparison, 2 biological replicates are performed.
