A novel SET-domain-containing gene OsSET1 was isolated from rice (Oryza sativa L.). Its deduced protein consists of 895 amino acids. OsSET1 has a high degree of structure similarity to other SET-domain-containing genes such as CLF in higher plants and E(z) in animals. RT-PCR showed that the gene expresses throughout the entire plant. A transient expression assay in onion epidermis revealed that the OsSET1 protein is localized in nuclei. Over-expression of the SET domain of OsSET1 in Arabidopsis resulted in altered shoot development at seedling stages.
Key words: Gene expression regulation, rice, OsSET1, SET-domain-containing genes.
