Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Full frame distilled prediction
Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.

Abstract
Like their nuclear counterpart, the plastid and mitochondrial genomes of plants have to be faithfully replicated and repaired to ensure the normal functioning of the plant. Inability to maintain organelle genome stability results in plastid and/or mitochondrial defects, which can lead to potentially detrimental phenotypes. Fortunately, plant organelles have developed multiple strategies to maintain the integrity of their genetic material. Of particular importance among these processes is the extensive use of DNA recombination. In fact, recombination has been implicated in both the replication and the repair of organelle genomes. Revealingly, deregulation of recombination in organelles results in genomic instability, often accompanied by adverse consequences for plant fitness. The recent identification of four families of proteins that prevent aberrant recombination of organelle DNA sheds much needed mechanistic light on this important process. What comes out of these investigations is a partial portrait of the recombination surveillance machinery in which plants have co-opted some proteins of prokaryotic origin but have also evolved whole new factors to keep their organelle genomes intact. These new features presumably optimized the protection of plastid and mitochondrial genomes against the particular genotoxic stresses they face.
