UV Reactive Plants

Update: Oh I should also mention that I have not yet found any flowers which fluoresce. So maybe it's not anthocyanin - if I had an apple I could test this.
What-here-is-florescent-gamewherever I go. So, chlorophyll is not, but dust and mold are - mold fluoresces bright yellow (I'm having a bit of a problem with blight at the moment). But one of the stranger things I noticed, was that my tomato seedlings fluoresced red. And on the larger tomato plants, the undersides of the leaves and the newly growing ones also fluoresced red. And on the green onions, the bottom part of the stalks, that area glows red too. So, I'm guessing that it's areas of the plant which have little chlorophyll where this is occurring - or that the chlorophyll is not blocking the light. Most of the other plants I have examined don't fluoresce red. So does anybody know specifically what is fluorescing? I speculate that it might be another pigment like anthocyanin, but that's totally a wild guess.
