Extracellular vesicle-mediated small RNAs: Emerging effectors in fungal pathogenesis
Plant Science Research WeeklyPlant pathogens are skilled manipulators, using specialized molecular weapons to weaken plant defenses and establish infection. Traditionally, scientists have focused on secreted proteins, known as effectors, that help pathogens suppress plant immune responses. But recent discoveries show that fungal…
Plant cells secrete diverse RNA species, including small RNAs, long noncoding RNAs and circular RNAs
The Plant Cell: In a NutshellKarimi et al. showed that Arabidopsis plants secrete numerous RNAs, which are associated with proteins and are located outside extracellular vesicles. Plant Cell. (2022) https://doi.org/10.1093/plcell/koac043
