Genetic interactions and natural variation underlying S-RNase-independent unilateral incompatibility in Solanum.

The Plant journal : for cell and molecular biology - 1 Aug 2025

Qin Xiaoqiong, Ng Sarah, Paul Elizabeth, Chetelat Roger T

Abstract excerpt

Pistils of self-incompatible (SI) species/populations typically reject pollen of related self-compatible (SC) species/populations, but not vice versa, a pattern known as unilateral incompatibility (UI). UI is complex and includes both S-RNase-dependent and S-RNase-independent mechanisms. Pistils of Solanum pennellii LA0716 (SC, no S-RNase) reject pollen of cultivated tomato, Solanum lycopersicum (SC); UI in this...
