Spatiotemporal proteomic remodeling of lipid droplets drives astaxanthin accumulation in H. pluvialis
This study constructs the first spatiotemporal proteomic atlas of *Haematococcus pluvialis* lipid droplets, revealing that stage-specific protein remodeling drives astaxanthin accumulation through a conserved two-step sequestration model that integrates multi-organelle functions for carbon repartitioning and redox homeostasis.
