Genome fluidity. The case of plants Authors Pere Puigdomènech i Rosell Josep Maria de Casacuberta i Roger Abstract The publication of complete sequences of large genomes is becoming routine. The analysis of these data provides a general outlook of genome structures, which helps us to understand how a genome is built up. A genome is obviously not a completely random polymer, but nor is it a fixed, optimised structure. Plant genomes seem to be particularly fluid, which allows large differences in size and organisation to occur in closely related species. Here we analyse some aspects of plant genome structure and comment on several mechanisms that contribute to genome varability, in particular the function of mobile elements that are abundant and active components in the plant genomes.
