Annotated Information
Function
OsDDM1b is required for the maintenance of DNA methylation on newly replicated DNA strands in rice genome like OsDDM1a.It mainly keeps the methylation level on repeated sequences rather than single copy sequence.
Mutant Phenotype
We can observe dwarf phenotypes in OsDDM1 mutant lines generated through the antisense technology. Except the dwarf phenotypes, no other significant specific morphological aberration was observed in independent OsDDM1 mutant lines. However, in some sublines, researchers observed reduced fertility relative to normal lines.

Evolution
OsDDM1b(Os03g0722400) is 93% identical to another gene OsDDM1a(Os09g0442700) in the predicted amino acid sequences and shows 60 % identity to Arabidopsis DDM1. However, considering maize, no simple orthologous relationships exits between the two maize DDM1-like genes-CHR101,CHR106 and OsDDM1.OsDDM1b and OsDDM1a both consist of 15 exons and 14 introns and the DNA sequence similarity shared by these two genes is 81%, even including intron sequences. Compared to the Arabidopsis DDM1, these two genes' exon–intron structure is similar. The start codon of the Arabidopsis DDM1 locates in the first exon, but it is in the second exon for the OsDDM1 genes. The protein product of OsDDM1b gene is 849 amino acids in length. Both rice OsDDM1a and OsDDM1b proteins contain the eight signature amino acid motifs diagnostic for SWI2/SNF2 proteins.

By comparing the DDM1-like prteins encoded in the maize genome,Arabidopsis DDM1 and the mouse LSH with the two rice DDM1-like proteins,the envolution relationship is showed as below.We can see that they appear to have arisen by a relatively recent duplication event.
