Abstract
  • Meiosis is essential for sexual reproduction and required for the formation of sperm and egg; its central events are the associations between homologous chromosomes (homologs), including pairing, synapsis, recombination and segregation. During recombination, the exchange of DNA between homologs results in new allelic combinations between the parents and offspring and among individual progeny (Wang and Copenhaver, 2018). This genetic variation is the foundation for biodiversity and speciation. The phenotypic diversity that results from genetic variation is also used to develop new elite traits during commercial plant and animal breeding practices. Thus, understanding the molecular mechanisms drive and regulate plant meiosis can accelerate crop improvement, and provide a theoretical foundation for the development and maintenance of new agricultural varieties.
