Phospholipid biosynthesis is a core metabolic pathway that affects all aspects of plant growth and development. One of the earliest step in this pathway is mediated by choline/ethanolamine kinases (CEKs), enzymes in the Kennedy pathway that catalyze the synthesis of the polar head groups found on the most abundant plant phospholipids. The Arabidopsis genome encodes four  CEK s.  CEK1-3  have been well characterized using viable mutants while  CEK4  encodes an essential gene, making it difficult to characterize its effects on plant development and responses to the environment. We have isolated an EMS-induced allele of  CEK4  called  bumpy stem  ( bst ).  bst  plants are viable, allowing the effects of decreased  CEK4  function to be characterized throughout the Arabidopsis life cycle.  bst  mutants have a range of developmental defects including ectopic stem growths at the base of their flowers, reduced fertility, and short roots and stems. They are also sensitive to cold temperatures. Supplementation with choline, phosphocholine, ethanolamine, and phosphoethanolamine rescues  bst  root phenotypes, highlighting the flow of metabolites between the choline and ethanolamine branches of the Kennedy pathway. The identification of  bst  and characterization of its phenotypes defines new roles for  CEK4  that go beyond its established biochemical function as an ethanolamine kinase.
