| Research Abstract |
In order to evaluate whether the inhibition of growth after germination induced by histone deacethylase (HDAC) inhibitors was a universal phenomenon in higher plants, Trichostatin A treatment was performed to three Arabidopsis related species. As a result, transition to the vegetative phase was inhibited in all, and it was suggested that HDAC is involved in this transition universally. On the other hand, expression of C-LEC1 gene and DNA methylation level in upstream region of C-LEC1 were observed peaks in early timing of embryo induction in carrot. The transiently increasing of DNA methylation was derived from CxG and CHH contexts that might be controlled by de novo type methylase.
