The structure and allelic diversity of the self-incompatibility locus (S-locus) in diploid potatoes inferred from genome sequences and transcriptome data from styles and pollen.

Abstract excerpt

Gametophytic self-incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self-compatibility (SC)/self-incompatibility (SI) system in the Solanaceae have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum L. S-RNases are pistil determinants of GSI and multiple S-RNase alleles...
