Inferences on the number and frequency of S-pollen gene (SFB) specificities in the polyploid Prunus spinosa.

Heredity - 1 Oct 2008

Vieira J, Santos R A M, Ferreira S M, Vieira C P

Abstract excerpt

In flowering plants, self-incompatibility is a genetic mechanism that prevents self-fertilization. In gametophytic self-incompatibility (GSI), pollen specificity is encoded by the haploid genotype of the pollen tube. In GSI, specificities are maintained by frequency-dependent selection, and for diploid species, at equilibrium, equal specificity frequencies (isoplethy) are expected. This prediction has been tested...
