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...

Maternal inheritance of mitochondria breaks down in the cold when a mitochondrial DNA degrading nuclease is defective, resulting in biparental inheritance that can rescue mitochondrial mutations and g...

This study shows that many small RNAs in Capsella rubella pollen originate from maternal tissues. These mobile small RNAs support proper pollen development, revealing that non-cell-autonomous small RN...

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...

Author summary The function of proteins is governed by specific interactions with other molecules, notably small molecules (compounds, such as metabolites). The precise nature of the protein-compound ...
