Mitochondrial fostering: the mitochondrial genome may play a role in plant orphan gene evolution (bioRxiv)

Orphan genes are those that are found in only a single species. In trying to understand the origin of orphan genes, O’Conner and Li have found that many of these orphan genes are likely to have originated as mitochondrial genes, as many are nuclear genes whose encoded proteins are targeted to the mitochondria…

Review: Matrix redox physiology governs the regulation of plant mitochondrial metabolism through post-translational protein modifications

Mitochondrial metabolism provides ATP and reducing power to drive myriad reactions in the plant cell, and is constantly being fine-tuned in response to environment and demands. Post-translational modifications (PTMs) of proteins, including redox reactions of methionine and cysteine and carbamylation…
