About
Dorota Paczesniak is a plant evolutionary biologist whose research centers on the ecological and evolutionary consequences of reproductive mode variation, particularly the transition from sexual to asexual (apomictic) reproduction in plants. Her work explores how apomixis—the clonal production of seeds—shapes seed development, endosperm genetics, and offspring fitness. In her highly cited 2022 study on *Boechera*, she demonstrated that apomictic plants often require paternal genetic contributions for proper endosperm formation (pseudogamy), and that this constraint generates significant phenotypic diversity in seed size, endosperm traits, and germination success. By linking reproductive system variation to measurable seed traits, Paczesniak’s research provides critical insights into the evolutionary trade-offs of asexuality, including the maintenance of genetic variation and the ecological implications of reduced recombination. Her work has garnered attention for its integration of developmental biology, population genetics, and plant ecology, and she is recognized for advancing our understanding of how reproductive innovations like apomixis influence plant adaptation and diversification.
