RNA (ribonucleic acid) editing is an important process for maintaining essential functions of encoded proteins at the RNA level. Recent studies show that RNA editing is a widespread phenomenon that occurs in various land plants, including the liverworts, mosses, hornworts, lycopods, ferns, and flowering plants. However, there have been few comparative studies of chloroplast RNA editing within and between groups except for ferns.
