| Abstract: | EMBRYONIC FLOWER 2 (EMF2) gene plays a major role in maintain vegetative development and repress flower development. Here, we present the cloning, characterization and tissue-specific expression of a putative EMF2 (OsEMF2) gene in Oryza sativa. The full-length cDNA of OsEMF2 was 1899 bp and contained an 1872 bp open reading frame (ORF) encoding a 624 amino acid protein. Homologous analysis showed that OsEMF2 contain a single conserved C2H2-type zinc finger motif. Sequence alignment shows that there is a homology between the deduced amino acid sequence of OsEMF2 and EMF2 in Zea mays (55%). Moreover, pI of OsEMF2 are predicted. The tissue-specific expression pattern of OsEMF2 reveals that it is abundant in shoot apical meristem and inflorescence meristem, while its expression level is much lower in leaf, root, immature seed and callus. |
