Mitochondrial Molecular Adaptations and Life History Strategies Coevolve in Plants [PDF]

, 2008
Messenger RNA secondary structure prevents mutations at functionally important sites. Mutations at exposed sites would cause micro-adaptations, niche-specialization, and therefore, can be thought to promote K-strategists. Exposing, rather than protecting,
