  • Sexual reproduction in many angiosperm plants involves self-incompatibility (SI), which is one of the most important mechanisms to prevent inbreeding. SI is genetically controlled by the S-locus, and involves highly specific interactions during pollination between pollen and the pistil on which it lands. This results in the rejection of incompatible (‘self’) pollen, whereas compatible (‘non-self’) pollen is allowed to fertilize the plant. In Papaver rhoeas, S-proteins encoded by the stigma… CONTINUE READING
