Unequal segregation of SRK alleles at the S locus in Brassica cretica.

Aaltonen, Kristina LU ; Widén, Björn LU and Ceplitis, Alf LU (2008) In Genetical Research 90(3). p.223-228
Abstract
In the Brassicaceae plant family, which includes the Arabidopsis and Brassica genera, self-incompatibility (SI) is controlled by genes at the S locus. Using experimental crosses, we studied the pattern of inheritance of S-locus alleles in the wild species Brassica cretica. Four full-sib families were established and unequal segregation of alleles at the SRK SI gene was found in one family. The segregation distortion acted in favour of a recessive (class II) allele and was best explained by some form of gametic-level selection. Our findings are discussed in the light of theoretical predictions of differential accumulation of deleterious mutations among S-locus alleles.
