The Spotted-dilute controlling element system in maize involves an autonomous Spotting factor (Spf), and a receptor at the r1 locus haplotype R1-r(spotted dilute2). Its relationship with other maize transposable element systems is poorly characterized. Through development of a genetic tester that carries receptors for both the Spotted-dilute and the En/Spm controlling element systems, we determined that both receptors respond equally to Spf and En/Spm and that Spf is therefore a member of the En/Spm family of controlling elements.
