Ten Years of Gene Discovery for Meiotic Event Control in Rice

Meiosis is the crucial process by which sexually propagating eukaryotes give rise to haploid gametes from diploid cells.Several key processes,like homologous chromosomes pairing,synapsis,recombination,and segregation,sequentially take place in meiosis.Although these widely conserved events are under both genetic and epigenetic control,the accurate details of molecular mechanisms are continuing to investigate.Rice is a good model organism for exploring the molecular mechanisms of meiosis in higher plants.So far,28 rice meiotic genes have been characterized.In this review,we give an overview of the discovery of rice meiotic genes in the last ten years,with a particular focus on their functions in meiosis.
