This study shows mtDNA can rapidly adapt to nuclear ETC mutations in C. elegans, with compensatory mutations in nd-1 significantly improving fitness.

The paper analyzes mtDNA polymorphism in natural C. elegans populations and compares it to experimental lines, finding differences in mutational biases and evidence of natural selection.

This study shows that natural selection in C. elegans maintains low TE expression, with increased TE expression observed in smaller populations due to reduced silencing efficiency.
