Abstract excerpt
Phosphatidylcholine (PC, lecithin) has long been considered a solely eukaryotic membrane lipid. Only a minority of all bacteria is able to synthesize PC. The plant-transforming bacterium Agrobacterium tumefaciens encodes two potential PC forming enzymes, a phospholipid N-methyltransferase (PmtA) and a PC synthase (Pcs). We show that PC biosynthesis and tumour formation on Kalanchoë plants was impaired in the...
