The natural history of the model fern Ceratopteris richardii provides opportunities for unique studies and makes it an important system to include in comparative work.

In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

The HMA domains of Pikp-1 and Pikm-1 NLR receptors have convergently evolved to bind AVR-PikD with high affinity through distinct evolutionary and biochemical paths.

Convolutional neural networks and graph partitioning algorithms can be combined into an easy-to-use tool for segmentation of cells in dense plant tissue volumes imaged with light microscopy.

The crystal structure of higher plant PSI-LHCI complex reveals intricate details responsible for light harvesting.

A nightshade family gene cluster creates phenotypic novelty in trichome defensive metabolites via evolution of lipid metabolic enzymes.

A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.

Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.

Fruit consumption of Jeholornis was evidenced and indicates seed dispersal was present from early in avian radiation.

Polymorphic residues of a vacuolar Ca²⁺ sensor site in TPC1 channels differ between species of Brassicacea and Fabaceae and lead to distinct TPC1 gating behavior.
