Place, is also the center of various metabolic activities and regulation and control, and there is complicated signal with nucleus and other organelles hands over
Stream.
PPR families are one of maximum families for finding in plant, there is 477 members in paddy rice, are one kind with 35 letters
And amino acid is the protein of recurring unit's continuous arrangement composition, these degeneracy amino acid repeated are referred to as PPR motifs.
This family is largely positioned in mitochondria or chloroplaset, influence plastid RNA montage, editor, processing and stability
Deng.Although coding PPR families largely exist in plant, the influence rice chloroplast gene RNA montage having now been found that
PPR albumen is but very limited.The PPR albumen for being positioned at chloroplaset found in paddy rice has OsPPR1, (Gothandam et
