Abstract
This entry represents a group of plant pentatricopeptide repeat-containing proteins, including PPR5 from maize and rice and At2g30780/At4g39620/At2g48000 from Arabidopsis. PPR5 is a chloroplastic protein that binds to single-stranded RNA and influences both RNA stability and splicing [ 1 ]. It has been shown to stabilise the chloroplast trnG pre-RNA by directly binding to a group II intron, where it protects an endonuclease-sensitive site and stimulates splicing [ 2 ]. At4g39620 is involved in embryo morphogenesis [ 3 ].
