One of the main actions of this hormone is described by the acid growth hypothesis.
One of the main actions of this hormone is described by the acid growth hypothesis. By activating proton pumps in the cell membrane, this hormone causes the pH of the cell wall to decrease, ultimately making it more elastic. They also can induce ethylene synthesis in high concentrations and inhibit senescene and abscission. Indole-3-acetic acid is the prominent example of this group of hormones, which help ensure that the main stem of the plant grows the most by inhibiting development of the lateral buds. For 10 points, name this class of plant hormones which promote cell division and maintain apical dominance.
