✦ Synopsis

Maize DNAs isolated from wild type and from mutants caused by the insertion of transposable genetic element Ds at the gene encoding endosperm sucrose synthase (Sh) are compared in Southern blotting experiments by hybridization to Sh-cDNA cloned in pBR322. Differences observed between the DNAs of the wild type and the mutants indicate the presence of additional DNA at the Sh locus and/or DNA alterations that have occurred subsequent to the insertion of Ds. A double mutant exhibiting the recessive phenotype of both sh and the closely linked gene bz lacks DNA hybridizing to the probe and may be a deletion.
