The synthesis of this hormone relies on a nitrilase, and its actions are mediated by the actions ofthe SCF-TIR1 ubiquitination complex.
The synthesis of this hormone relies on a nitrilase, and its actions are mediated by the actions ofthe SCF-TIR1 ubiquitination complex. It moves through the organism via PIN proteins in a processcalled polar transport, and its action was discovered by Fritz Went using agar blocks. This hormonetriggers the activity of expansins, which loosen the cross-linking between cellulose fibrils, amechanism known as (*) acid growth. Indole-3-acetic acid is the principle type of this hormone, which issynthesized in shoot tips and controls apical dominance. Among its actions are regulating gravitropism andphototropism, and it stimulates the production of ethylene in order to suppress lateral growth. For 10 points,name this class of plant hormones.
