Do plants destory auxin intentionally?

  1. Mar 5, 2009 #1
    So - plants bending towards light. Light kills auxin. Shaded side grows faster so plant bends toward light.

    Was this an evolutionary mechanism developed by plants? Thinking of natural selection - were plants with auxin more successful since they could p/s more which meant higher rates of reproduction? Or is the denaturing of auxin by sunlight and the resultant bending just coincidence? I may be blurring the lines but, I'm asking whether the "bending" mechanism was a product of natural selection or if plants just "lucked out" with this mechanism...still blurring the lines I think, but - hopefully someone can make some sense of this for me. Thanks,
