The “Ins and Outs” of ER–Chloroplast Lipid Trafficking

Karki 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…

Autophagy regulates lipid biosynthesis and turnover

Fan et al. explore the roles of autophagy in Arabidopsis lipid metabolism. Plant Cell https://doi.org/10.1105/tpc.19.00170 By Jilian Fan, Linhui Yu and Changcheng Xu Biology Department, Brookhaven National Laboratory Background: Autophagy is a self-eating process during which cytoplasmic materials…

How a Plant Plankton Copes with Stress

Yamaoka et al. report that the mRNA of a Chlamydomonas bZIP transcription factor is spliced by CrIRE1 under ER stress, and the resulting protein protects cells via modulating lipid remodeling. Plant Cell https://doi.org/10.1105/tpc.18.00723 By Yasuyo Yamaoka and Youngsook Lee Background: The endoplasmic…
