Auxins regulate processes like phototropism, gravitropism, and fruit development, enhancing horticultural practices. Additionally, it covers synthetic auxins like 2,4-D and 2,4,5-T, used as selective herbicides that affect broad-leaved plants while sparing grasses, though their mechanisms are not fully understood.

Notably, zeatin facilitates mitosis in seed germination. Cytokinin signaling includes plasma membrane receptors, activation of nuclear transcription factors, and gene regulation, resulting in proteins essential for these cellular functions.
