A cellulose synthase interactome uncovers BAG proteins as regulators of cellulose synthase homeostasis
Cellulose synthase complexes build the load-bearing cellulose microfibrils of plant cell walls, yet how the abundance of their catalytic CELLULOSE SYNTHASE A (CESA) subunits is maintained remains unclear. Here, we used multi-bait TurboID proximity labelling with ten cellulose-synthesis-associated baits and six subcellular controls to define a high-confidence cellulose synthase neighbourhood.…
