These compounds are commonly synthesized via the tryptamine pathway or the IPA pathway, and one mode of their action involves the formation of ARF homodimers.  These compounds also lead to the activation of by H+-ATPase pumps
These compounds are commonly synthesized via the tryptamine pathway or the IPA pathway, and one mode of their action involves the formation of ARF homodimers.  These compounds also lead to the activation of by H+-ATPase pumps in the acid growth model.  First fully characterized by Fritz Went using agar blocks and coleoptiles, this hormone is commonly synthesized in apical meristems and distributed throughout the plant via polar transport.  Also responsible for phototropism, the formation of lateral roots, and apical dominance, FTP, name this class of plant hormones which includes indoleacetic acid and the herbicide Agent Orange.
