| Outline of Final Research Achievements |
Using simultaneous analysis of different classes of phytohormones and comprehensive transcriptome analysis over the dormancy cycle of Monochoria vaginalis seeds in the field, we investigated the molecular regulation of dormancy cycling. Phytohormone contents within seeds showed less seasonal changes and were not linked to the dormancy cycling. Transcriptome analysis identified candidate genes involved in dormancy cycling and the transcriptome dynamics were linked to not only seasonal changes but also seed age.
