Study on plant unfolded protein response in the flowering time regulation
Stress generally slows down the growth and development of an organism, but in some cases it acts as a facilitating stimulus. Plants are no exception to this rule, and in poor conditions such as high temperatures and dryness, flowering is accelerated along with growth delay. Studies on Arabidopsis, a model plant for molecular genetics, have found that flowering is significantly delayed by causing a functional reversal of the transcription factor bZIP28, which mediates the regulation of gene expression in response to endoplasmic reticulum stress, a type of intracellular stress. In this project, I will explore the molecular mechanisms of bZIP28-mediated flowering regulation and expand our understanding of stress-induced flowering promotion.


In recent years, the field of molecular genetics has experienced major changes such as the universalization of mass sequencing technology, the automation of phenotypic analysis using artificial intelligence, and the spread of highly accurate genome editing technology. By quickly catching up with the ongoing changes in the research environment, I will move forward from molecular genetics, which has focused on the analysis of the function of individual genes, to research that aims to understand the dynamics and networks of biological phenomena.
