Abstract excerpt
Phosphate availability constrains growth across plant and algal lineages, yet the intracellular regulatory mechanisms linking external phosphate signals to acclimation responses remain incompletely understood. Protease families are highly expanded in photosynthetic eukaryotes, but whether individual protease paralogues have evolved regulatory roles in nutrient signaling is largely unexplored. Here, we identified...
