Outline of Final Research Achievements |
To investigate the involvement of 12-oxo-phytodienoic acid (OPDA)in the regulation of Apx2 and HsfA2 expression under high light in Arabidopsis, I analyzed using fad3/fad7/fad8 mutants which can not synthesis OPDA. However, there was no significant difference in the transcript level of Apx2 and HsfA2 between the wild-type plants and fad/3fad7/fad8 mutants at 1 h after high light irradiation, suggesting that OPDA was not involved in these induction within 1 hour. RNA-seq analysis showed that the transcript levels of 239 genes were decreased (<2-fold) in the fad3/fad7/fad8 mutants compared with the wild-type plants. This finding suggests that the high light inducible expression of these genes was regulated by oxilipin containing OPDA.
