| Outline of Final Research Achievements |
The purpose of this study was to clarify how the rice transcription factor OsWRKY23 is involved in the accumulation of aromatic components contained in the cell wall of rice and to clarify the influence on plant traits.
In the OsWRKY23-SRDX transgenic plants, there were alterations in the expression of genes involved in the biosynthesis of long-chain fatty acids and of genes acting on polymerization of lignin and suberine monomers, but in the OsWRKY23 deficient mutant in which the mutation was introduced in the region adjacent to the PAM sequence, the expected decrease in the expression of ASFT11 was not observed and no direct involvement in the accumulation of the aromatic component was confirmed.
From this stuy it was shown that OsWRKY23 is indirectly involved in the accumulation of aromatic components.
