Too Active in ER Fusion? Here Comes LUNAPARK to the Rescue

Sun et al. found that Arabidopsis LUNAPARK, a protein evolutionarily conserved in eukaryotes, is an E3 ligase that promotes the degradation of ROOT HAIR DEFECTIVE3, an ER fusogen.

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…

The Surprisingly Similar Glycomes of Maize and Arabidopsis Golgi

Okekeogbu et al. compare the glycomes and proteomes of the Golgi in grasses and dicots, finding that the differences in cell wall architecture are not reflected in differences between polysaccharides produced in the Golgi.
