The “Ins and Outs” of ER–Chloroplast Lipid Trafficking
Research, The Plant Cell, The Plant Cell: In a NutshellKarki et al. revisit the long-standing question of how and where lipid trafficking occurs during galactolipid synthesis. They report evidence for metabolically distinct pools of phosphatidylcholine, suggesting an underlying spatial organization in the ER–chloroplast metabolic interactions. Plant Cell…
