    Abstract : OsSRT1 is a NAD+-dependent histone deacetylase, closely related to the human SIRT6 that plays key roles in genome stability and metabolic homeostasis. In this work, we investigated the role of OsSRT1 in ricericeSubject Category: Commodities and Products

    genes and transposons in developing seeds. In addition, OsSRT1 was detected to directly bind to starch metabolism genes such as OsAmy3B, OsAmy3E, OsBmy4, and OsBmy9. Our results suggested that OsSRT1-mediated histone deacetylation is involved in starch accumulation and transposon repression to regulate normal seed development.
