Sequence Variation and Haplotype Structure Surrounding the Flowering Time Locus FRI in Arabidopsis thaliana.
(2002) In Genetics 161(1). p.289-298- Abstract
- Linkage disequilibrium in highly selfing organisms is expected to extend well beyond the scale of individual genes. The pattern of polymorphism in such species must thus be studied over a larger scale. We sequenced 14 short (0.5-1 kb) fragments from a 400-kb region surrounding the flowering time locus FRI in a sample of 20 accessions of Arabidopsis thaliana. The distribution of allele frequencies, as quantified by Tajima's D, varies considerably over the region and is incompatible with a standard neutral model. The region is characterized by extensive haplotype structure, with linkage disequilibrium decaying over 250 kb. In particular, recombination is evident within 35 kb of FRI in a haplotype associated with a functionally important... (More)

The region is characterized by extensive haplotype structure, with linkage disequilibrium decaying over 250 kb. In particular, recombination is evident within 35 kb of FRI in a haplotype associated with a functionally important allele. This suggests that A. thaliana may be highly suitable for linkage disequilibrium mapping. (Less)
