The mobilization of sulfur (SUF) system is one of three systems involved in iron–sulfur cluster biosynthesis and maintenance. In eukaryotes the SUF system is specific for the plastid and therefore of symbiotic origin. Analyses in cryptophytes showed a unique genetic compartmentalization of the SUF system, which evolved by at least two different gene transfer events. We analyzed one of the components, SufD, in the cryptophyte Guillardia theta and in Arabidopsis thaliana . We demonstrated that SufD fulfils house keeping functions during embryogenesis and in adult plants in A. thaliana .
