Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae

open access: yesApplications in Plant Sciences, Volume 14, Issue 3, May-June 2026.
Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...
