RNA secondary structures affecting the C-to-U editing sites. a Barplot showing the percentages of sites located in structured RNA regions. Structured means the hairpin regions defined by software RNAfold. P-value is calculated by Fisher’s exact test. b RNA structures around two cytidines (position 362 and position 376) on gene ATMG00580 (NADH dehydrogenase subunit 4). The two cytidines are fully edited in A. thaliana but completely unedited in A. lyrata. C-to-U event at site ATMG00580:362 causes a missense change from ACA (Thr) to AUA (Ile) and C-to-U at site ATMG00580:376 causes a missense change from CGU (Arg) to UGU (Cys)
