| Outline of Final Research Achievements |
Aim of this research is to increase plant biomass. I quantitatively analyzed phenotypes of the plants which are treated with a library comprising many small molecular chemicals and then looked for useful chemicals. First, I added chemicals into Arabidopsis seeds, grew them under blue light and evaluated images obtained. I calculated quantitative scores to 22 items using a newly-developed computer program. As a result, I picked up a candidate chemical, #203, of which treatment strongly increased hypocotyl length and decreased size of cotyledons. Such phenotypes were seen only under blue light but not under other light waves. Transcriptome analysis of plants treated with #203 or an analogous chemical revealed that expression changes of blue-light-related genes only in #203-treated plants hardly occurred.
