Currently, neither cloning S and Z gene nor identifying their products was successful. Phalaris coerulescens can be used as a model plant to study SI in the Poaceae. Segregating population and comparative genomics strategy were used to map S and Z, constructing high-resolution mapping of the target loci so that map base clone S and Z genes. It is a research orientation and hot spot of self-incompatibility in Poaceae.
