This study demonstrates that RNA from herbarium specimens can be used for transcriptomics, validating the functional use of archival mRNA from a 1956 plant specimen.

The paper develops a computational model to study petal pattern evolution, finding that boundary cell types emerge spontaneously during bullseye pattern formation.

This study uses transcriptomic data to infer evolutionary relationships and molecular evolution patterns in Apocynaceae, identifying gene duplications and rate shifts associated with adaptations.

This study identifies genetic mutations in the BERRY1 locus causing bullseye pattern reduction in Trionum Complex flowers and links this to pollinator behavior and speciation.

This study identifies syringomycin as a key necrotizing toxin that enables Pseudomonas syringae to infect diverse plant lineages, including non-flowering species.

CAnDI identifies conflicts in homologous gene trees to better understand convergent trait evolution, showing genomic evidence for shared molecular bases in carnivorous plant traps.

The paper evaluates EPSY, concatenation, and coalescent-based methods under high ILS, finding EPSY more accurate in resolving contentious phylogenetic relationships.
