SummaryTo improve crop quality and yield, breeders need to control the fertility of stamens, the male organs that produce pollen within sacs called anthers. For example, it would be ideal to manipulate at will the release of pollen from anthers. However, this firstly requires a detailed understanding of how anther cells themselves activate pollen release. In barley, this activation seems to be triggered by the phytohormone auxin and requires enzymes to separate specific cells from each other to finally open the anthers.
