A new biophysical model enables the reconciliation of ultrastructural and tissue level measurements on parameters affecting intercellular communication, and provides novel functional insight into experimental findings.

Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.
Despite BCAAs being de novo-synthesized in chloroplasts, TOR activation by BCAAs is conserved in plants and triggers a re-organization of actin and actin-associated endomembranes.

Superfamilies of trans-species small RNAs from the parasitic plant Cuscuta have sequence variation that correspond to synonymous site variation in host plant target mRNAs.

Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.
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.
