The lab seeks to understand plant stress responses by studying RNA degradation.

AboutAbout the lab
Seeing how plants live through the workings of RNA.
The Chiba Lab studies how RNA-mediated regulation of gene expression contributes to the distinctive physiological phenomena of plants.
Currently, the lab focuses in particular on the role of RNA in plant stress responses.
Regulation of gene expression through mRNA degradation is thought to be especially effective when a rapid response is needed.
Using the model plant Arabidopsis thaliana, the lab investigates these questions with methods from molecular genetics and physiology.
Key terms
- mRNA
- RNA that copies the genetic information of DNA and serves as the template for making proteins
- Regulation of gene expression
- The mechanism that controls which genes are active, when, and to what extent
- Microarray
- A method for measuring the activity levels of many genes at once

Because plants lack the means to move, they must respond quickly to changes in their environment. By understanding the regulation of both mRNA synthesis and degradation, the lab aims to uncover the mechanisms behind the sophisticated environmental responses of plants.
