摘要

Robustness is the preservation of the phenotype in the face of 遺傳 and environmental perturbations. It has been argued that robustness must be an essential fitness component of RNA 病毒es owed to their small and compacted 基因組s, high 突變 rates and living in ever-changing environmental conditions. Given that 遺傳 robustness might hamper possible beneficial 突變s, it has been suggested that 遺傳 robustness can only evolve as a side-effect of the 演化 of robustness mechanisms specific to cope with environmental perturbations, a theory known as plasto遺傳 congruence. However, empirical evidences from different viral systems are contradictory. To test how 適應 to a particular environment affects both environmental and 遺傳 robustness, we have used two strains of turnip mosaic poty病毒 (TuMV) that differ in their de
