Witryna4 maj 2024 · The term auxin is derived from the Greek word auxein, which means "to grow." While many synthetic auxins are used as herbicides, indole-3-acetic acid ( IAA) is the only naturally occurring auxin that shows physiological activity (Figure 16.1. 1 ). Auxin is synthesized in apical meristems, young leaves, and developing seeds.

Witryna15 kwi 1999 · Auxin transport plays an important role during root gravitropism.
