O-glycosylation is a critical post-translational modification (PTM) regulating protein function, yet its role in plant transcription factors remains poorly understood.
Nutrient cues shape adipose homeostasis; however, the mechanism by which inorganic signals engage organelle networks to drive white fat browning remains unclear. Here, we identify a nitrate-Sialin2 pathway that converts dietary nitrate into a spatially confined thermogenic program. Sialin2 localizes...
