Outline of Final Research Achievements |
It has been revealed that the transcriptional network controlled by the NAC transcription factor VND7 is crucial for the differentiation of xylem vessel cells. In this research, to understand the regulatory mechanisms underlying the expression and function of VND7 gene, we elucidated the epigenetic modification of VND7 gene region, cis- and trans-factors for VND7 gene expression, functional regulation of VND7, and dynamics of small RNA during the vessel differentiation. As a result, it was revealed that the expression of VND7 gene is negatively controlled by DNA methylation and histone H3K27 trimethylation, that a GATA transcription factor is a possible trans-factor of VND7, that VND7 could alter its transactivation activity through the S-nitrosylation modification, and that various miRNA species could regulate transcriptional network in which VND7 gene is participating.
