Distribution of Mu transposon insertion sites in FGS genes. A, Proportion of Mu insertions located in each decile of the cds, 5′ UTR, and 3′ UTR (B73, blue; W22, red). B, All FGS genes targeted by Mu transposons in B73 and W22 (SRP028545) were divided into gene sets based on their length (1% to 10% represent the shortest set of genes and 91% to 100% represent the longest genes) and the number of genes with insertions in each cds decile, 5′ UTR and 3′ UTR (B73, blue; W22, red).
