Plants adapt to stress through differential growth mediated by the trans-Golgi Network (TGN) and the TRAPPII complex. Shaggy-like kinases target TRAPPII-specific subunits, affecting stress response pathways. TRAPPII interacts with signaling components, suggesting a role as a cellular hub. The TRS120 subunit is phosphorylated by AtSKs, impacting adaptive growth decisions under stress conditions. Mutations in TRS120 affect plant responses to osmotic stress and differential growth under additive stress. TRS120 phosphovariants show contrasting effects on seed germination and growth responses, highlighting the role of phosphorylation in mediating adaptive growth decisions.
