Comment
| Open AccessShining light on dinoflagellate photosystem I
Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp. was structurally characterized using cryo-Electron Microscopy (cryo-EM). These analyses revealed a distinct organization of the PSI supercomplex, including two previously unidentified subunits, PsaT and PsaU, and shed light on interactions between light harvesting antenna proteins and the PSI core. These results have implications with respect to the evolution of dinoflagellates and their association with cnidarians.

| Open AccessA plant NLR receptor employs ABA central regulator PP2C-SnRK2 to activate antiviral immunity
Huang et al. show how plant Sw-5b NLR mimics the ABA receptor to activate ABA-dependent antiviral immunity via the PP2C-SnRK2 complex. They reveal that Sw-5b NLR induces ABA accumulation, upregulates ABA response genes, and triggers defense against viral infections by releasing SnRK2 from PP2C inhibition.
