The paper analyzes molecular data from historical herbarium specimens and modern samples to assess the status of Azolla species in California, finding potential extirpation of Azolla microphylla.

The paper uses genome-wide sequencing to study the evolutionary relationships and biogeography of Hawaiian Doryopteris, finding that phylogeny is more linked to geography and climate than morphology.

The paper develops a birth-death-reticulation model to analyze phylogenetic networks and applies it to study diversification in ferns, finding evidence that polyploids have lower diversification rates than diploids.

The paper analyzes genetic diversity and demographic history of Azolla populations in California, identifying three groups and finding evidence of recent invasions for two newly reported taxa.

The paper presents a chromosome-level genome assembly of Azolla caroliniana, improving upon previous assemblies and aiding in understanding its population genetics and taxonomy.

The paper characterizes the microbiome of the nitrogen-fixing fern Azolla, revealing multiple endosymbionts with varying transmission modes and stages of symbiosis evolution.

PURC v2.0 improves sequence inference for polyploid phylogenetics by incorporating ASV methods alongside OTU clustering, enhancing accuracy over previous OTU-based approaches.

This study uses deep phylogenomics to trace the origin and evolution of nuclear auxin response proteins across land plants, revealing key evolutionary steps and non-canonical roles.
