Dichogamy — the temporal separation of anther dehiscence and stigma receptivity — is ubiquitous in angiosperms. Using field investigations, Mendelian inheritance experiments, multi-omics analysis based on haplotype-resolved genomes and validation of gene function, we identify SMPED1 as a novel gene that controls the synchrony of sex organ behaviour in angiosperms.
