SUMMARY Apomixis – clonal seed production in plants is a rare yet phylogenetically widespread trait that has recurrently evolved to fix hybrid genotypes over generations. absent from major crop species and been seen as holy grail of plant breeding due its potential propagate vigor perpetuity. Here we exhaustively review recent progress, bottlenecks, the individual components gametophytic apomixis (avoidance meiosis, skipping fertilization by parthenogenesis, autonomous endosperm development), sporophytic apomixis. The Mitosis instead Meiosis system now successfully set up three ( Arabidopsis , rice, tomato), significant hurdles remain for universal bioengineering gametes. Parthenogenesis engineered even more species, incomplete penetrance still remains an issue; discuss choice parthenogenesis genes BABY BOOM PARTHENOGENESIS WUSCHEL ) also how drive egg cell‐specific expression. identification pathways engineer development would allow fully production, here challenges remain. achievements engineering synthetic rice at high show great remaining obstacles toward implementation this are addressed. Overall, practical examples suggest field flourishing agricultural systems could soon take place.
