The endpoints of an inversion in wheat chloroplast DNA are associated with short repeated sequences containing homology toatt-lambda

Abstract

The endpoints of an inversion in wheat chloroplast DNA are shown to be associated with copies of a short repeated sequence. Recombination across the repeats in an inverted configuration may have been responsible for the inversion, although they are currently in a direct orientation owing to a second inversion. The repeated sequence contains an element homologous to the core of the bacteriophage lambdaatt-site, which can function as such in vivo.
