The CYP72 family has been sequenced in Arabidopsis (accession number AB023038) and there are 8 genes and one pseudogene present. This is similar in size to the Arabidopsis Z97338 gene cluster of CYP702 and 705 genes that has 8 genes and two pseudogenes. The spacing between the genes is less than 1000bp except for one gap of about 6000bp. See the nomenclature files CYP72A7 to CYP72A15 for nucleotide positions. The sequences have been placed in the FASTA Arabidopsis file.
