Elevated levels of Activator transposase mRNA are associated with high frequencies of Dissociation excision in Arabidopsis.

Abstract excerpt

The Activator (Ac) element of maize is active at a low frequency in Arabidopsis. To determine whether this is due to poor expression of the Ac transposase gene, we obtained and studied 19 Arabidopsis transformants containing fusions of the octopine synthase (ocs), nopaline synthase (nos), cauliflower mosaic virus (CaMV) 35S, or Ac promoters to the transposase open reading frame. These transformants were examined...
