Walk in the park yields biological treasure

is resistance in Arabidopsis and we can identify which pathways are involved in that resistance. The next question is: How is the leaf miner responding to the presence or absence of these toxic molecules? Does it care? Clearly, it does. There is a cost for detoxifying, but what is it?"

Ecological questions are waiting to be answered as well.

"We know that the leaf mining habit has evolved probably 25 times in insects," Whiteman said, "mostly in beetles, butterflies, moths, some wasps and saw flies. It's not present in the other insect orders, but why? How has selection shaped the ability of these insects to colonize an organism with a potent defense response? We want to develop the Scaptomyza lineage as a system for answering questions like these. This is our lab rat system."
