Sequence duplication is nowadays recognized as an important mechanism that underlies the evolution of eukaryote genomes, being indeed one of the most powerful strategies for the generation of adaptive diversity by modulating ...

The biogenesis of the plant mitochondrial respiratory chain needs the coordinated synthesis and assembly of the products of more than 100 genes located in the nucleus and within the organelle. One of the factors that ...

Background Driven essentially by random genetic drift, subfunctionalization has been identified as a possible non-adaptive mechanism for the retention of duplicate genes in small-population species, where widespread ...

mitochondrial genomes are generally thought to be under selection for compactness, due to their small size, consistent gene content, and a lack of introns or intergenic spacers. As more animal mitochondrial genomes are ...

Abstract Background DNA repair genes encode proteins that protect organisms against genetic damage generated by environmental agents and by-products of cell metabolism. The ...
