Gene Details:

• MSU gene ID: LOC_Os08g02640
• RAPdb gene ID: Os08g0120000
• Gene Symbol: RPS14 OsSDH2-1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The rice mitochondrial genome has a sequence homologous to the gene for ribosomal protein S14 (RPS14), but the coding sequence is interrupted by internal stop codons.
• The nuclear RPS14 gene encodes a long N-terminal extension showing significant similarity to a part of mitochondrial succinate dehydrogenase subunit B (SDHB) protein from human and a malarial parasite (Plasmodium falciparum).
• Considering that the rice mitochondrial genome lacks the sdhB gene but contains the RPS14-related sequence, transfer of the sdhB gene seems to have occurred before the transfer of the RPS14 gene.
• The migration of the mitochondrial RPS14 sequence into the already existing sdhB gene could bestow the capacity for nuclear expression and mitochondrial targeting.
• A single nuclear transcript encoding mitochondrial RPS14 and SDHB of rice is processed by alternative splicing: Common use of the same mitochondrial targeting signal for different proteins.
• Taken together, OsSDH2-1 plays a crucial role in leaf senescence and yield formation in rice.
• OsSDH2-1 gene was expressed in all organs tested, with higher expression in leaves, root tips, ovary and anthers.
• OsSDH2-1 protein was targeted to mitochondria.
