Chen H, Berg C, Samuli M, Sotola V, Sweigart A, Yuan Y, et al.
New Phytol . 2024 Dec; 245(5):2255-2267. PMID: 39697054
Pollination syndromes are a key component of flowering plant diversification, prompting questions about the architecture of single traits and genetic coordination among traits. Here, we investigate the genetics of extreme...

Whitener M, Mangelson H, Sweigart A
Evolution . 2024 May; 78(8):1464-1477. PMID: 38766685
Polyploidy occurs across the tree of life and is especially common in plants. Because newly formed cytotypes are often incompatible with their progenitors, polyploidy is also said to trigger "instantaneous"...
3.
Mantel S, Sweigart A
Mol Ecol . 2024 Jan; 33(4):e17261. PMID: 38174628
The evolution of postzygotic isolation is thought to be a key step in maintaining species boundaries upon secondary contact, yet the dynamics and persistence of hybrid incompatibilities in naturally hybridizing...

Farnitano M, Sweigart A
J Evol Biol . 2023 Sep; 36(10):1393-1410. PMID: 37691442
Postmating reproductive isolation can help maintain species boundaries when premating barriers to reproduction are incomplete. The strength and identity of postmating reproductive barriers are highly variable among diverging species, leading...

Sotola V, Berg C, Samuli M, Chen H, Mantel S, Beardsley P, et al.
Genetics . 2023 Aug; 225(3). PMID: 37603838
The evolution of genomic incompatibilities causing postzygotic barriers to hybridization is a key step in species divergence. Incompatibilities take 2 general forms-structural divergence between chromosomes leading to severe hybrid sterility...

Mantel S, Sweigart A
bioRxiv . 2023 Aug; PMID: 37577468
The evolution of postzygotic isolation is thought to be a key step in maintaining species boundaries upon secondary contact, yet the dynamics and persistence of hybrid incompatibilities in sympatric species...

New Phytol . 2022 Aug; 236(4):1545-1557. PMID: 35999713
The endosperm, a tissue that nourishes the embryo in the seeds of flowering plants, is often disrupted in inviable hybrid seeds of closely related species. A key question is whether...
