Rates out-of recombination can vary certainly genomic regions when you look at the eukaryotes, and this refers to believed to enjoys major effects on their genome company with respect to foot structure, DNA repeat density, intron dimensions, evolutionary prices and you will gene purchase. In the extremely thinking-fertilizing species such as for example Arabidopsis thaliana, but not, heterozygosity is expected as strongly quicker and you can recombination will be way less productive, with the intention that the affect genome providers are going to be greatly quicker.
Abilities
Right here we examined theoretically the brand new joint outcomes of recombination and you will worry about-fertilization for the base constitution, and examined the fresh new predictions that have genomic study in the complete A good. thaliana genome. We show that, contained in this species, each other codon-use bias and you will GC content do not correlate with the regional rates regarding crossing-over, inside the contract with this theoretic abilities.
Results
I finish you to definitely degrees of inbreeding modulate the end result out of recombination into feet structure, and maybe almost every other genomic has (such as for instance, transposable ability personality). I believe inbreeding should be thought about when interpreting models off molecular advancement.
Record
Recombination could be a key reason for the progression out-of genome team during the varieties eg yeast, animals, Drosophila and you will C. elegans. On these types, genomic provides such as for instance nucleotide polymorphism [1–4], GC content [step one, 5–8], codon prejudice [6, 9], intron proportions [ten, 11], transposable element occurrence [12–14] replacing costs [15–17] and you will gene buy are different extensively during the genome, and they are correlated towards local speed regarding crossing-over.
