Cell communication lockdown: How plants close plasmodesmata in MAMP immune response
Plant Science Research WeeklyHow do plants protect themselves from microbial invaders? One response is the closure of plasmodesmata to stop the spread of microbial effector proteins that help pathogens evade the immune response, protecting neighboring uninfected cells. While the phenomenon of plasmodesmata closure in response of…
Membrane lipid phosphoinositides signature the final step of plant cytokinesis
Plant Science Research WeeklyPhosphoinositides (membrane lipids with cytosolic inositol headgroups carrying phosphate residues at various positions) serve as road markings for membrane and membrane/cytoskeleton dynamics. Here, Lebeco et al. add further detail to the map. Previously the authors showed that the plant-specific enzyme…
