Seeds run on a father-mother gene tug-of-war
bioRxiv · 2026-07-25
Scientists mapped which genes in a wild mustard plant's seeds are switched on only when inherited from the father versus the mother, revealing that seeds carry a built-in genetic tug-of-war between parents that shapes how they grow.
1
Genomic imprinting in Arabidopsis arenosa endosperm affects only a limited set of biological pathways, pointing to specific dosage-sensitive processes
2
The gene NRPE1 acts as a network hub, linking epigenetic regulation to endosperm development
3
Paternally expressed genes mainly reinforce other paternal genes, while maternally expressed genes regulate both paternal and maternal genes, consistent with a self-promoting paternal strategy versus a maternal buffering strategy
