Variation in frequency of plastid RNA editing within Adiantum (Pteridaceae) implies rapid evolution in fern plastomes

Blake Fauskee, Erin Sigel, Kathleen Pryer & Amanda Grusz
Premise Recent advances in studies of plant RNA editing have demonstrated that the number of editing sites can vary widely among large taxonomic groups (orders, families). Yet, very little is known about intrageneric variation in frequency of plant RNA editing, and no study has been conducted in ferns. Methods We determined plastid RNA editing counts for two species of Adiantum (Pteridaceae), A. shastense and A. aleuticum, by implementing a pipeline that integrated read mapping and...
