Name this class of chemicals explained by Frits Went, responsible for cell elongation in plants—the first plant hormone to be discovered.
Produced from tryptophan, parenchyma cells are responsible for this compound's polar transport through coleoptile tissue. It activates expansins which loosen cellulose microfibrils, in turn causing the target cell to take in water, according to the acid growth hypothesis. At high concentrations, it stimulates ethylene production, and as dicots are more sensitive to synthetic ones, it is often used as an herbicide. Responsible for vascular cambium growth and many tropisms, it is produced in meristem tissue.
