Description

We classified poaceae SI as type-6 gametophytically controlled by two multiallelic and independent loci, S and Z. Taking S as an example, stamen-expressed transmembrane polypeptides containing a domain of unknown function 247 (DUF247) can specifically recognize the pistil-specific peptide HPS10, resulting in the rejection of the self pollen.
