摘要: Many plants have a self‐incompatibility (SI) system in which the rejection of self‐pollen is determined by multiple haplotypes at a single locus, termed S. In the Solanaceae, each haplotype encodes a single ribonuclease (S‐RN ase) and multiple S‐locus F‐box proteins (SLF s), which function as the pistil and pollen SI determinants, respectively. S‐RN ase is cytotoxic to self‐pollen, whereas SLF s are thought to collaboratively recognize non‐self S‐RN ases in cross‐pollen and detoxify them via the ubiquitination pathway. However, the …
