What is Traumatin in biology?
Traumatin is a plant hormone and is secreted in response to wound or injury in plants. It is a precursor of related hormone traumatic acid, called as wound hormone since it appears around wound and it stimulate cells division.

How are Auxins used in horticulture?
In horticulture, auxins, especially NAA and IBA, are commonly applied to stimulate root initiation when rooting cuttings of plants. However, high concentrations of auxin inhibit root elongation and instead enhance adventitious root formation. Removal of the root tip can lead to inhibition of secondary root formation.
Which is wound hormone in plants?
Traumatic acid is a potent wound healing agent in plants (“wound hormone”) that stimulates cell division near a trauma site to form a protective callus and to heal the damaged tissue.
What does florigen do to plants?
Florigen (or flowering hormone) is the hypothesized hormone-like molecule responsible for controlling and/or triggering flowering in plants. Florigen is produced in the leaves, and acts in the shoot apical meristem of buds and growing tips.
How are gibberellins used in horticulture?
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. They are naturally produced by barley and other seeds.
Why do plants heal wounds?
Ability to repair This protein binds to and activates the expression of another gene (CUC2). These two together increase the production of a plant growth hormone called auxin at the wound site. The combination of these proteins and hormones gives the plant the ability to repair wounds.
How do plants heal their wounds?
Many animals and plants regenerate tissues or even whole organs after injury. Typically, specialized cells at the wound site revert to a ‘pluripotent’ state–via a process called dedifferentiation—which means they regain the ability to develop into the various cell types required for regeneration.
How do plants respond to injury?
Plants are also able to sense the injured tissue as an altered self and induce responses similar to those activated by pathogen infection. Endogenous molecules released from wounded tissue may act as Damage-Associated Molecular Patterns (DAMPs) that activate the plant innate immunity.
What is Vernalin in plants?
Vernalin is a hypothetical plant hormone that is thought to be synthesised by a low-temperature treatment during vernalisation, which induces flowering.
What is the role of Vernalin in plants?
Vernalin is a hormone-like substance produced in leaves during chilling (Cold) treatment. It is believed that it acts as a precursor of florigen hormone which induces flowering.
What are auxins and Gibberellins?
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.
