The emergence of the eukaryotes coincided with the diversification of histone proteins and their post-translational modifications by enzymes that constitute the core of eukaryotic chromatin. Yet the e...

Small molecules produced by TIR (Toll-interleukin-1 receptor) domains are essential for plant immune signaling. A central TIR-derived signal is 2'cADPR, a cyclic ADP-ribose (ADPR) molecule that is gen...

RNA viruses co-opt host endomembranes to form replication complexes, often triggering cellular stress and immune responses. Here, we show that Arabidopsis thaliana activates selective autophagy to res...

Using cryo-electron tomography, the authors reveal how plasmodesmata (plant cytoplasmic bridges) are gated by cell wall remodelling and how helical protein assemblies scaffold internal membranes, with...

The propagation of a viral infection from a host parent to its progeny is known as vertical transmission, or seed transmission in plants. It allows viral infections to rapidly spread locally via polle...

Huang et al. report that auxin drives the assembly of its cell-surface receptors, TMKs, with efflux carrier PIN1 at the plasma membrane, creating a self-organizing module. This receptor-transporter ne...

In gravistimulated roots, gravity perception in the columella redirects the flow of the plant hormone auxin toward the lower root side, where it inhibits cell elongation for downward root bending. Thi...

Sea slugs steal foreign chloroplasts and store them in specialized organelles that facilitate photosynthesis and eventual digestion to mediate starvation resistance.
