Other claims from this paper (6)
- Observation Rates of evolution at synonymous sites vary along Arabidopsis chromosomes.
- Mechanism Synonymous-site rate variation suggests mutation rates vary on genomic scales, perhaps as a function of recombination rate.
- Association Rates of evolution at nonsynonymous sites correlate most strongly with expression patterns.
- Association WGD genes evolve more slowly on average than nonduplicated genes.
- Association WGD genes evolve more slowly on average than non-WGD duplicates.
- Mechanism The authors hypothesize that expression levels and patterns are the major determinants of nonsynonymous rate variation and a critical determinant of gene retention after duplication.
