title: Pattern of ac transposition in maize.
abstract: Analysis of four nearby transpositions of Ac from the waxy locus indicate that the element can reinsert to either side. The cause of the asymmetry observed for P-VV transpositions is discussed and a model is presented to account for the high frequency of close reinsertions of Ac.
