Comparing models for S-Rnase-based self-incompatibility

Abstract

S-Rnase-Based Self-Incompatibility (Si) Is Known To Occur In Three Families Of Flowering Plants: Solanaceae, Rosaceae And Plantaginaceae. It Is The Most Widely Distributed Si System Described So Far. It Is A Single-Locus Gametophytic System. Gene Pairs At The S-Locus Determine S-Specificity On The Pistil And The Pollen Sides Of Si. This Chapter Describes These Genes (S-Rnase On The Pistil Side And S-Locus F-Box (Slf/Sfb) On The Pollen Side), The Non-S-Locus Genes That Contribute To Their Functions And Models For S-Specific Pollen Rejection.
