Résumé en anglais

We have compared the length of noncoding organelle DNA spacers in a broad sample of plant species characterized by different life history traits to test hypotheses regarding the nature of the mechanisms driving changes in their size. We first demonstrate that the spacers do not evolve at random in size but have experienced directional evolutionary trends during plant diversification. We then study the relationships between spacer lengths and other molecular features and various species attributes by taking into account population genetic processes acting within cell lineages. Comparative techniques are used to test these relationships while controlling for species phylogenetic relatedness. The results indicate that spacer length depends on mode of organelle transmission, on population genetic structure, on nucleotide content, on rates of molecular evolution, and on life history traits, in conformity with predictions based on a model of intracellular competition among replicating organelle genomes.< Réduire
