Story summary

Researchers found that whole-genome duplications in flowering plants formed tight clusters during past climate crises.
Yves Van de Peer’s Cell analysis of 470 plant genomes confirmed the timing and linked the clusters to the 66-million-year-old asteroid impact.
Polyploid plants’ extra gene copies boost photosynthesis and tolerate prolonged temperature or light extremes.
Sandra Pitta says the results could help breeders develop crops resilient to today’s climate change.
