Abstract

Abstract:

RNA editing is a post-transcriptional level process of processing and modification that makes mature RNA different from its DNA template strand by base insertion, deletion, or replacement, which is a universal correction mechanism in plants to restore conserved amino acids that have been altered by DNA mutations. PPR proteins (pentatricopeptide repeat protein) are an important class of RNA editing factors that are widely distributed in plants and constitute one of the largest families of higher plants. At present, many studies have shown that it plays an important role in plant growth and development. Its main function is to affect the expression of organelle genes by participating in the processing of RNA precursors, such as achieving the transformation of RNA C-U, participating in intron splicing, affecting mRNA stability and translation, etc., thus affecting photosynthesis, respiration, plant development and environmental response. In this paper, the classification, localization, function and mechanism of PPR protein reported in recent years are reviewed, the application prospect of PPR protein is also prospected, aiming to provide theoretical basis for the subsequent research and analysis of the function of PPR protein and its application.

Key words: PPR protein, RNA editing, RNA processing, mechanism
