The Green Algal Pigment Caulerpin as a Plant Growth Regulator

Article abstract of DOI:10.1016/S0031-9422(00)84752-4

Caulerpin, a green algal pigment possessing a unique bis-indole structure, has been shown to be a plant growth regulator.Root growth assays were conducted with caulerpin and its hydrolysis product, and the results were compared with indole-3-acetic acid (IAA), indole-3-pyruvic acid (IPA) and indole-3-acrylic acid (IAcA).This study has indicated that caulerpin, in essence a dimer of indole-3-acrylic acid, behaves much like the indole auxins.Key Word Index - Caulerpa; alga; caulerpin; auxin; plant growth regulator.
