Well‐resolved phylogeny supports repeated evolution of keel flowers as a synergistic contributor to papilionoid legume diversification

New Phytologist, Volume 247, Issue 1, Page 369-387, July 2025.
Summary The butterfly‐shaped keel flower is a highly successful floral form in angiosperms. These flowers steer the mechanical interaction with bees and thus are hypothesized to accelerate pollinator‐driven diversification. The exceptionally labile evolution of keel flowers in Papilionoideae (Fabaceae) provides a suitable system to test this hypothesis.

The genetic basis of replicated bullseye pattern reduction across the Hibiscus trionum complex

New Phytologist, Volume 247, Issue 2, Page 863-883, July 2025.
Summary Colorful petal patterns fulfill important functions and constitute excellent systems to illuminate the evolutionary processes that generate morphological diversity or instead support the repetitive emergence of similar forms. Here, we combined phylogenomic approaches, genetic manipulations, molecular techniques, and bee behavioral experiments ...

The fitness effects of outcrossing distance depend on parental flowering phenology in fragmented populations of a tallgrass prairie forb

New Phytologist, Volume 247, Issue 2, Page 968-978, July 2025.
Summary The phenomena of isolation‐by‐distance and isolation‐by‐time shapecontra mating patterns and population genetic processes, such as inbreeding and outbreeding depression, which influence progeny fitness. However, the effects of parental isolation in time on offspring fitness remain understudied, especially in combination with isolation‐by ...

The chimeric gene orf610a reduces cotton pollen fertility by impairing the assembly of ATP synthase

Plant Biotechnology Journal, Volume 23, Issue 7, Page 2949-2962, July 2025.
Summary Cytoplasmic male sterility (CMS) serves as a pivotal tool for exploiting hybrid vigour and studying nuclear‐cytoplasmic interactions. Despite its long‐standing use in cotton breeding, the underlying mechanisms of the CMS‐D2 system remain elusive.
