RNase-related proteins (RRPs) are S- and S-like RNase homologs lacking the active site required for RNase activity. Here we describe the cloning and characterization of the rice (<I>Oryza sativa</I>) RRP gene (<I>OsRRP</I>). A single copy of <I>OsRRP</I> occurs in the rice genome. <I>OsRRP</I> contains three introns and an open reading frame encoding 252 amino acids, with the replacement of two histidines involved in the active site of RNase by lysine and tyrosine respectively. <I>OsRRP</I> is preferentially expressed in stems of wild-type rice and is significantly down-regulated in an increased tillering dwarf mutant <I>ext37</I>.
