Gene Details:

• MSU gene ID: LOC_Os07g08180
• RAPdb gene ID: Os07g0179000
• Gene Symbol: FLO22
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The present work indicated that FLO22 plays an important role in endosperm development and plant growth by participating in nad1 maturation and multi-site editing of mitochondrial mRNA.
• RNA-seq analysis showed that expression levels of many genes involved in starch and sucrose metabolism were significantly down-regulated in the FLO22 mutant compared with the wild type, whereas genes related to oxidative phosphorylation and the tricarboxylic acid (TCA) cycle were significantly up-regulated.
• Map-based cloning and complementation tests demonstrated that FLO22 encodes a mitochondrion-localized P-type PPR protein.
• In addition to involving in splicing as a P-type PPR protein, we found that FLO22 interacted with DYW3, a DYW-type PPR protein, and they may function synergistically in mitochondrial RNA editing.
