This study investigates reproductive barriers in Trichaptum abietinum using population genomics and in vitro crosses, finding pre-mating barriers correlated with genomic divergence and hybrid fitness linked to increasing divergence.

The paper investigates the repeatability of adaptation in sunflowers, finding that genomic regions with inversions contribute to adaptation even in species without such inversions.

This study re-evaluates homoploid reticulate evolution in annual sunflowers using whole genome resequencing, finding widespread admixture and ancient hybridization events across the genus.

The paper assembles the western redcedar genome and finds it has low genetic diversity, suggesting mechanisms like associative overdominance maintain genetic variation despite selfing.

This study identifies large haploblocks as key drivers of rapid local adaptation in Ambrosia artemisiifolia across different climates.

This study identifies QTLs underlying flowering time adaptation in common ragweed during its European invasion, revealing a concentrated genetic architecture with suppressed recombination in specific genotypes.

This study examines recombination, transposable elements, and deleterious mutations in sunflower species, finding that inversion homozygosity reduces mutation accumulation.

The paper identifies a single MYB transcription factor, HaMYB111, as the genetic basis for UV pigmentation diversity in sunflowers and shows its dual role in pollinator attraction and abiotic stress response.

The paper shows that current crop distributions do not align with their climate suitability, highlighting the need to consider non-climatic factors in agricultural strategies.

The paper investigates introgression in Helianthus annuus subsp. texanus using genome and phenotypic data, finding introgression from H. argophyllus rather than H. debilis as previously hypothesized.

The paper identifies novel splice forms in sunflower hybrids that may contribute to reproductive incompatibilities through co-evolution of spliceosomal components.

The paper examines how selection at different life stages maintains divergent adaptation between two sunflower ecotypes using demographic models and genome-wide data.

The paper reconstructs ancestral sunflower karyotypes and finds a high rate of chromosomal rearrangement with non-random translocations contributing to hybrid sterility.

The paper identifies seven chromosomal inversions in a dune sunflower ecotype that contribute to adaptive divergence and incipient speciation by associating with environmental variables and islands of differentiation.

This study examines hybrid phenotype patterns, finding hybrids often resemble one parent more than the other and show trait mismatches, with mismatch having a stronger fitness impact than parent bias.

The paper identifies large haplotype blocks associated with ecotypic differentiation in sunflowers, showing how structural variation maintains adaptive alleles despite hybridization.
