Return to the Trip Overview

Red and white:
Phil is busily researching the pigmentation in Sarracenia. In particular, he is investigating the gene that governs anthocyanin-free pigment mutations. There is some argument in the literature as to whether the famous "veinless" Sarracenia purpurea plants result from hybridization between normal red plants and anthocyanin-free plants. (I talk a lot about the veinless plants in my Ontario 2003 field trip report.) Phil believes that the veinless mutation is unrelated to the mutation that gives rise to anthocyanin-free plants. It made for an interesting conversation, listening to his perspectives. He certainly has the room to do his experiments on a large scale and he has compelling data to support his arguments!

The red Sarracenia leucophylla above, by the way, is not part of this study, but it is lovely nonetheless. Phil thinks this red plant probably owes its striking coloration to some backcrossing with other Sarracenia, and I agree with him. But regardless of its origin, doesn't this red and pink plant contrast spectacularly with the green and white ones?
