Tomato Mutations (IMAGE)
Caption
Different combinations of mutations can affect the size of tomatoes unpredictably. In this image, the first column shows an unmutated (WT) tomato. The second and third columns show tomatoes with a single mutation in a region of the promoter (R1 or R4) for fruit size gene SlCV3. The individual mutations have little effect on fruit size. But the combination of these two mutations (R1 + R4) yields a much bigger fruit.
