Figure 4. EcoTILLING in maize. Portion of a gel image showing the IRD700 channel of a comparison of 24 inbreds to the B73 genome. Gene model for this target is given at top and diagrammed at left of gel with black boxes for exons. Open boxes indicate bands resulting from polymorphisms within exons that are present in duplicate samples (not shown) and have complementary sized products labeled with IRD800 dye. Asterisks indicate 200-bp size and lane marker.
