Excess nonsynonymous substitution of shared polymorphic sites among self-incompatibility alleles of Solanaceae.

Proceedings of the National Academy of Sciences of the United States of America - 1 Nov 1991

Clark A G, Kao T H

Abstract excerpt

The function of the self-incompatibility locus (S locus) of many plant species dictates that natural selection will favor high levels of protein diversity. Pairwise sequence comparisons between S alleles from four species of Solanaceae reveal remarkably high sequence diversity and evidence for sh...
