Arabidopsis	At5g19200	Catalyzes the reduction of 3'-oxosphinganine (3- ketodihydrosphingosine/KDS) to sphinganine (dihydrosphingosine/DHS), the second step of de novo sphingolipid biosynthesis.	Sphingolipids in the root play an important role in regulating the leaf ionome in Arabidopsis thaliana.; 2011; DOI: 10.1105/tpc.110.079095; PMID: 21421810; https://pubmed.ncbi.nlm.nih.gov/21421810/
