Abstract excerpt
To elucidate the molecular basis of loss of self-incompatibility in Lycopersicon, S-RNases and HT-proteins were analysed in seven self-compatible (SC) and three self-incompatible (SI) taxa. No or low stylar RNase activity was a common feature in most SC taxa examined, in contrast to the uniformly high levels of activity found in all SI species. The S-RNase gene is most likely deleted in the four red-fruited SC...
