The Impact of TOR-S6K-eIF5A Signaling on Translational Control is Key to Plant Root Development
Nutrient-responsive Target of Rapamycin (TOR)-S6 kinase (S6K) signaling coordinates plant growth with protein synthesis, but how it interfaces with translation elongation to produce specific developmental outputs remains unclear. Here, we identify eukaryotic translation factor 5A (eIF5A) as an S6K-associated phosphoprotein in Arabidopsis thaliana. S6K1 and S6K2 associate with all three eIF5A…
