Primordial cyanobacterial PSI structure.

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.

Guanosine tetraphosphate (ppGpp) is a pivotal regulator of chloroplast activity that is required for acclimation to nitrogen limitation in the model plant Arabidopsis.

Liquid-liquid phase separation of a rhabovirus phosphoprotein initiates viral factory formation of barley yellow striate mosaic virus, a plant negative-sense RNA virus, and host casein kinase 1-mediated phosphorylation inhibits phase separation and virus infection.

To effectively ward off some of the most damaging groups of filamentous pathogens, plants rely on an evolutionarily conserved syntaxin function to block the pathogen from entering the host cell and proliferate.

Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.

Localized lignin impregnations, forming a pan-endodermal net-like diffusion barrier strongly relies on stabilizing signals from neighbors.

Cation chloride cotransporter CCC1 has a central function in plant cells and is the missing ion efflux component of the transport circuit necessary to regulate pH in the lumen of the trans-Golgi-network/early endosome, the major cargo hub in plant cells.

The perception of endogenous RALF signaling peptides modulates the plasma membrane nanoscale organization of receptor kinases to regulate plant immune signaling.

The Arabidopsis N6-methyladenosine (m⁶A) binding proteins ECT2 and ECT3 act redundantly in the cytoplasm to regulate m⁶A-containing mRNAs whose abundances are reduced in ect2/ect3/ect4 knockout plants although the locations of their polyadenylation sites remain unaffected, contrary to currently held beliefs.
