Examples
- Auxins are a class of phytohormones involved in plant cell elongation and cell division, and play a significant role in plant morphogenesis.
- Phytohormones such as gibberellin regulate plant growth by stimulating cell elongation and cell division in specific tissues.
- Ethylene, a phytohormone produced in response to stress or injury, triggers fruit ripening and senescence, allowing for seed dispersal.
- Plant development is controlled by a complex interplay of phytohormones, including auxins, gibberellins, cytokinins, abscisic acid, and ethylene.
- The gaseous phytohormone ethylene is also involved in programmed cell death and the formation of flowers, fruits, and seeds.
