FTP, name this first plant hormone to be discovered, which promotes coleoptile expansion and fruit growth.
Synthetic versions of this hormone can be used as herbicides in eudicots. It is carried through parenchyma tissue by polar transport, which is named for the higher concentration of its transport protein at the basal ends of cells. It stimulates both cell division in the vascular cambium and root formation, but in one of its better-known functions changes in pH and membrane potential cause increased turgor and cell wall plasticity. This leads to cell elongation according to the acid growth hypothesis. The natural form of it in plants is called indoleacetic acid.
