Auxins: Auxins promote cell elongation and are crucial for various growth processes, including phototropism, gravitropism, and apical dominance.
Cytokinins: Cytokinins stimulate cell division and influence various aspects of plant growth and development, including shoot and root formation.
Gibberellins: Gibberellins are involved in stem elongation, seed germination, and flowering, influencing overall plant height and development.
Abscisic Acid (ABA): ABA regulates responses to environmental stresses such as drought and plays a role in seed dormancy and stomatal closure.
Ethylene: Ethylene is involved in various aspects of plant growth, including fruit ripening, leaf and flower senescence, and responses to mechanical stress.
Brassinosteroids: Brassinosteroids promote cell elongation, cell division, and overall plant growth, influencing various developmental processes.
Jasmonates: Jasmonates play a role in plant defense mechanisms against herbivores and pathogens, as well as in the regulation of reproductive processes.
Strigolactones: Strigolactones are involved in the regulation of shoot branching, root development, and the interaction with symbiotic mycorrhizal fungi.
