Arabidopsis	At1g19440	3-ketoacyl-CoA synthase 4.	No verified direct reference in this release
Arabidopsis	At2g16280	Involved in the elongation of C22 to C24 fatty acids, which are precursors for the biosynthesis of cuticular waxes, aliphatic suberins, and membrane lipids, including sphingolipids and phospholipids.	Arabidopsis 3-ketoacyl-coenzyme a synthase9 is involved in the synthesis of tetracosanoic acids as precursors of cuticular waxes, suberins, sphingolipids, and phospholipids.; 2013; DOI: 10.1104/pp.112.210450; PMID: 23585652; https://pubmed.ncbi.nlm.nih.gov/23585652/
Arabidopsis	At4g34510	Active on saturated acyl-CoAs up to C22.	Substrate specificity of Arabidopsis 3-ketoacyl-CoA synthases.; 2006; DOI: 10.1016/j.bbrc.2006.05.162; PMID: 16765910; https://pubmed.ncbi.nlm.nih.gov/16765910/
Arabidopsis	At2g26640	Active on both saturated and mono-unsaturated acyl chains C16 to C20.	Substrate specificity of Arabidopsis 3-ketoacyl-CoA synthases.; 2006; DOI: 10.1016/j.bbrc.2006.05.162; PMID: 16765910; https://pubmed.ncbi.nlm.nih.gov/16765910/
Arabidopsis	At1g68530	Contributes to cuticular wax and suberin biosynthesis.	CUT1, an Arabidopsis gene required for cuticular wax biosynthesis and pollen fertility, encodes a very-long-chain fatty acid condensing enzyme.; 1999; DOI: 10.1105/tpc.11.5.825; PMID: 10330468; https://pubmed.ncbi.nlm.nih.gov/10330468/ | Alterations in CER6, a gene identical to CUT1, differentially affect long-chain lipid content on the surface of pollen and stems.; 2000; DOI: 10.1105/tpc.12.10.2001; PMID: 11041893; https://pubmed.ncbi.nlm.nih.gov/11041893/
