Introduction of Research
Control of gene expression is exerted by multiple steps such as transcription, RNA processing and export, mRNA stability, translation and post-translational events. Recent discovery of small RNAs has enhanced the impact of post-transcriptional regulation, in particular alterations of mRNA stability and translation on gene regulations. Control of mRNA turnover is important not only for changing the level of mRNA, but also for determining the transition time of mRNA, which is critical for quick response to environmental changes. Translational regulation is also important to determine the functional protein level. The goal of our projects is to demonstrate the importance of mRNA turnover and translational controls in the regulating gene expression in response to stress conditions in plants. We are trying to understand the molecular mechanism of mRNA stability and translational controls in response to stress by using genetic and biochemical approaches.
