In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.
Constraint-based modelling predicts C4 photosynthesis evolves under resource limitation from an ancestral ground state of C3 photosynthesis and attributes divergent metabolic routes in extant C4 subtypes to light.

Expression of plant immune genes is controlled by the opposing actions of ubiquitin ligases and deubiquitinases that modify the master coactivator NPR1, thereby regulating its intrinsic transcriptional activity.

Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
S-type anion channel activity, which promotes stomatal closure and improves anti-fungal immunity in plants, is directly regulated through phosphorylation by a kinase of the chitin receptor complex.

Structure-led protein engineering can expand the effector recognition profile of plant intracellular NLR immune receptors, providing a proof-of-principle for the development of novel disease resistance mechanisms in plants.

In lateral roots, cells employ a novel pathway to cell edges to control directional growth, which acts independently of the leading paradigm of oriented deposition of cellulose microfibrils at faces.
The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.
