Abstract

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.

摘要

玉米中的斑点-稀释控制元件系统涉及一个自主的斑点因子（Spf），以及r1位点单倍型R1-r（斑点稀释2）处的一个受体。它与其他玉米转座元件系统的关系鲜为人知。通过开发一种携带斑点-稀释和En/Spm控制元件系统受体的遗传测试品系，我们确定这两种受体对Spf和En/Spm的反应相同，因此Spf是控制元件En/Spm家族的成员。
