Difference Between Auxin and Gibberellin

The main difference between auxin and gibberellin is that the auxin promotes the growth of the shoot system whereas gibberellin promotes stem elongation, germination, and flowering. Furthermore, auxin plays a role in apical dominance whereas gibberellin has no role in apical dominance.

How are Auxins different from gibberellins?

Auxin does not help in breaking seed and bud dormancy. Gibberellin plays a major role in seed germination, breaking seed and bud dormancy. It promotes root formation. It does not promote rooting.

What are auxins and gibberellins?

Key Terms. gibberellin: any of a class of diterpene plant growth hormones that stimulate shoot elongation, seed germination, and fruit and flower maturation. auxin: a class of plant growth hormones that is responsible for elongation in phototropism and gravitropism and for other growth processes in the plant life cycle.

What is the difference between auxin and cytokinin?

Answer. Cytokinins are the plant hormones that promote cell division and cell differentiation in the plant root and shoot system.

Difference Between Auxin and Cytokinin.

What are the function of gibberellins?

Evidence suggests that gibberellins stimulate the growth of main stems, especially when applied to the whole plant. They are also involved in the bolting (elongation) of rosette plants (e.g., lettuce) after exposure to certain environmental stimuli such as long periods of daylight.

What does gibberellin mean?

: any of several growth-regulating plant hormones that promote cell elongation and activity of the cambium, induce parthenocarpy, and stimulate synthesis of nucleic acids and proteins.

What is the function of auxin?

Auxin is a key regulator of plant growth and development, orchestrating cell division, elongation and differentiation, embryonic development, root and stem tropisms, apical dominance, and transition to flowering.

What are the 5 plant hormones?

Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides.

What is the role of cytokinin and gibberellin hormone?

Cytokinins promote RNA synthesis and stimulate protein and enzyme activities in tissues. Kinetin and benzyl-aminopurine are the most frequently used cytokinins in plant cell cultures. The Gibberellins is mainly used to induce plantlet formation from adventive embryos formed in culture.

Why auxin is not a hormone?

Although auxin may act at low concentrations and can be transported, it is not produced in a specific tissue. Auxin may also be too pleiotropic to be considered a hormone. ... Thus, it is not possible to attribute a specific function to auxin.

Is gibberellin an auxin?

GIBBERELLIN. Gibberellin causes some similar effects in plants as auxin, but it is a very different hormone. ... Gibberellins play an important role in several developmental stages in plants, but their claim to fame is making stems longer. Gibberellins promote stem elongation between nodes on the stem.

What are two uses of cytokinins?

More cytokinin induces growth of shoot buds, while more auxin induces root formation. Cytokinins are involved in many plant processes, including cell division and shoot and root morphogenesis. They are known to regulate axillary bud growth and apical dominance.

What is the main function of cytokinin?

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, ...
