Species Oryza sativa (Rice) [ GR_tax:013681 ]
Accession GR:0100506
Gene Symbol rrp
Gene Name RNAse related protein 
Synonyms (3)
E.C. Numbers (0)
Pathway Reactions (0)
Chromosome No. 9
Gene Type CDS (Protein coding)
Has Phenotype no
Description It is a single copy gene in O. sativa. Lacks endoribonuclease activity (RNAse) due to replacement of histidine amio acid residues from the active site by lysine and tyrosine. mRNA expressed preferentially in stem/culm at three and eight leaf stage (booting stage). Very low amount of expression detected in leaves at three and eight leaf stages. No expression in roots.
Curator Comment The expression profile was carried out on JX89 and ext37 germplasm accessions. The ext37 was derived by from JX89 by EMS mutagenization. The ext37 has increased tillering dwarf phenotype and it shows down regulation of rrp gene at three leaf stage. No changes observed at eight leaf stage.
