- It has several important roles. development of the embryo leaf formation phototropism gravitropism apical dominance fruit development abscission root initiation and development the shade-avoidance effect
- Auxin is produced in the plant tip, controls vertical growth in shoots, and lateral growth in roots. This is because as the plant grows, it needs more water and minerals. Auxin, as a result, will build up and cause lateral growth in the root system, which allows the plant to receive more nutrients. Auxin in the shoot tip is transported to the shady or dark side of the plant, causing that side to grow and therefore bend the plant towards the light or other stimulus.
