The dynamic evolution of mobile open reading frames in plastomes of Hymenophyllum Sm. and new insight on Hymenophyllum coreanum Nakai.

ABSTRACT: In this study, four plastomes of Hymenophyllum, distributed in the Korean peninsula, were newly sequenced and phylogenomic analysis was conducted to reveal (1) the evolutionary history of plastomes of early-diverging fern species at the species level, (2) the importance of mobile open reading frames in the genus, and (3) plastome sequence divergence providing support for H. coreanum to be recognized as an independent species distinct from H. polyanthos. In addition, 1C-values of H. polyanthos and H. coreanum were measured to compare the genome size of both species and to confirm the diversification between them. The rrn16-trnV intergenic regions in the genus varied in length caused by Mobile Open Reading Frames in Fern Organelles (MORFFO). We investigated enlarged noncoding regions contain
