Proposed model: ASK1 integrates the plant stress-responsive proteome by dynamically transitioning from ABA-driven signaling networks to drought-induced proteostasis assemblies, functioning through both SCF E3 ligase–dependent and independent mechanisms.

Our proximity labeling and quantitative proteomics suggest that ASK1/SKP1 assembles condition-specific networks, acting both within SCF E3 #ubiquitin ligases and through noncanonical interactions to coordinate #plant stress adaptation

Dynamic ASK1 proximity networks uncover SCF-dependent and noncanonical roles in ABA and drought adaptation Plants rely on rapid proteome remodeling to withstand fluctuating environmental conditions, yet how the ubiquitin system dynamically coordinates these multilayered responses remains unclear. Here we d...
