Comparative organelle genome analysis of the sister genera Ceratocephala and Myosurus (Ranunculaceae) reveals fast evolutionary rates in arid and aquatic environments

Plastid (rpo-, rps-, rpl-) and mitochondrial (nad-, ccm-) genes constitute the predominant functional categories within the FSGs, implying that they may play an important role in adaptation to specific habitats. The Ceratocephala-specific six FSGs and predicted protein structural changes of ycf1, rps4 and ccmFC may be related to the adaptation of this genus to dry habitats in the late Oligocene. The Myosurus-specific four FSGs and predicted protein structural change of ycf1 may be associated with the adaptation of this genus to aquatic habitats. These findings suggest that the increases in evolutionary rates and predicted protein structural changes of organelle genes may facilitate organisms to adapt specific habitats.

Abstract

Plastid (rpo-, rps-, rpl-) and mitochondrial (nad-, ccm-) genes constitute the predominant functional categories within the FSGs, implying that they may play an important role in adaptation to specific habitats. The Ceratocephala-specific six FSGs and predicted protein structural changes of ycf1, rps4 and ccmFC may be related to the adaptation of this genus to dry habitats in the late Oligocene. The Myosurus-specific four FSGs and predicted protein structural change of ycf1 may be associated with the adaptation of this genus to aquatic habitats. These findings suggest that the increases in evolutionary rates and predicted protein structural changes of organelle genes may facilitate organisms to adapt specific habitats.
