What are the uses of gibberellins?

Gibberellins are a group of plant hormones responsible for growth and development. They are important for initiating seed germination . Low concentrations can be used to increase the speed of germination, and they stimulate cell elongation so plants grow taller.

What is cytokinin used for?

Cytokinins were originally defined as chemicals that induce cell proliferation and trigger callus differentiation to shoot when applied with auxins, but now it is known that cytokinins play a key role in many aspects of plant growth and development [3], including embryogenesis, maintenance of root and shoot meristems.

What is the main function of gibberellins?

Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence. GAs are one of the longest-known classes of plant hormone.

How do humans use cytokinins?

Cytokinins are plant hormones and play essential roles in regulating plant growth and development. They also have diverse pharmacological effects in animals and humans. Cytokinin ribosides inhibit growth or cause apoptosis in various cell lines derived from diverse malignancies including those with a mutant p53 gene.

What are the functions of gibberellins and cytokinins?

Gibberellins (GAs) and cytokinins, are instrumental in many growth processes (Bernier 1988; Chen and Shepley, 1975; Heldt et al., 2011) such as initiation of floral parts, flowering itself, fruiting, leaf and stem morphology, and seed germination.

How are auxins, cytokinins and gibberellins affect plants?

All physiological aspects of plants are affected by plant hormones (chemical messengers), including auxins, cytokinins, and gibberellins. During phototropism and gravitropism, the plant hormone auxin controls cell elongation. The plant hormone cytokinin promotes cell division, controling many developmental processes in plants.

What is the function of the gibberellin in plants?

In doing so, it encourages cell growth and elongation in the stems and between nodes. In some species of plant, gibberellin is involved in many more processes. These include flowering, fruiting, and senescence, or the natural death of leaves and other plant parts.

How does gibberellin affect the balance of proteins?

At the cellular level, gibberellin is influencing the balance of proteins. In doing so, it encourages cell growth and elongation in the stems and between nodes. In some species of plant, gibberellin is involved in many more processes. These include flowering, fruiting, and senescence, or the natural death of leaves and other plant parts.
