phototropin

Examples of phototropin in the following topics:

• Blue Light Response

  • The protein-based receptors, phototropins and cryptochromes, sense blue light to alter plant physiology accordingly.
  • Phototropins are protein-based receptors responsible for mediating the phototropic response in plants.
  • Phototropins belong to a class of proteins called flavoproteins because the chromophore is a covalently-bound molecule of flavin.
  • However, of all responses controlled by phototropins, phototropism has been studied the longest and is the best understood.
  • We now know that as light passes through a plant stem, it is diffracted and generates phototropin activation across the stem.
