Fig. 1.

Conceptual display of Helitron-mediated violation of gene colinearity among different maize lines. Hypothetical variable haplotypes of three maize inbreds are shown. The wild-type genes are numbered, and their exons are black boxes. Helitron insertions are red lines, and the exons of genes captured by Helitrons are shown as colored boxes. The 3′ palindromes of the Helitrons are shown as loops. The “vacant sites” in lines lacking Helitron insertions found in other lines are marked by red arrowheads.
