Ash, lilac, privet, jasmine, olive... the unique reproductive system of the Oleaceae deciphered !

To avoid inbreeding, plants in the Oleaceae family use an unusual genetic system that defines two unique compatibility groups. Its genomic and molecular bases have just been identified by two CNRS teams (including CRBE) associated with the universities of Toulouse and Lille. Published jointly in the journal Current Biology on April 15, 2024, their studies pave the way for a better understanding of the evolution of plant reproductive strategies, and should enable better control of olive tree pollination.
