Somatic variegation and germinal mutability reflect the position of transposable element Dissociation within the maize R gene.

Genetics - 1 Sept 1993

Alleman M, Kermicle J L

Abstract excerpt

The R gene regulates the timing and tissue-specificity of anthocyanin deposition during maize development. The Ac/Ds system of transposable elements was used to induce insertional mutants of the R-sc:124 allele during two cycles of mutagenesis. Of 43 unstable, spotted-aleurone mutants generated, 42 contain inserts of the Ds6 transposable element differing only in the position and orientation of the element. The...
