Mono- and digalactosyldiacylglycerols (MGDGs and DGDGs) are glycolipids that are central to plant metabolism and photosynthetic membrane biogenesis. Galvestine-1, a small molecule inhibitor of MGDG synthases that was identified in a high-throughput chemical screen in Arabidopsis thaliana, reveals a new role for these galactolipids in pollen-tube development.
