Indole-3-Butyric Acid (IBA) - A Product For Successful Research

 Hormones play an important role in the human body. They control and coordinate all of the body's functions, from metabolism to growth and development, and even human emotions, mood, and sleep.

Any changes in hormone deficiency or excess result in a physiological change. Similarly, like in humans, hormones control all aspects of plant growth and development. Environmental cues trigger the production of these potent hormone compounds. They are found in the leaves, flowers, shoots, roots, or fruits, depending on which hormone is activated.

Plant hormones are classified into five types: auxins, cytokinins, gibberellins, ethylene, and abscisic acid. Each hormone serves a specific purpose, and for oilseed, pulse, and cereal crops, auxins and cytokinins can significantly improve plant vigour, promote root and shoot growth, and reduce stress.

In this article, we will discuss auxin, identified as indole-3-butyric acid (IBA).

Auxins

You all have most likely seen auxins in action, but few of you must have realised it. Have you ever wondered why a plant bends toward the sun?

It's because of the auxin in the stem. Auxin is a component of cell growth and expansion and is typically found in actively growing plant parts, with the primary stem having the highest concentration.

Auxins work best when combined with another hormone. That's where cytokinins come in, collaborating to promote rapid, early nodal root development.

In a research, Auxins or Indole-3-butyric acid, are described as a regulator of growth and developmental processes in taller plants. In short, this potent root, shoot, and leaf regulator encourages cell elongation, which promotes growth. Some soil microorganisms are capable of producing indole-3-butyric acid, which regulates plant growth.

Indole-3-butyric acid (IBA)

Indole-3-butyric acid is a plant hormone in the auxin family that is found as an ingredient in many commercial horticultural plant rooting products. Aside from promoting root formation, it is used on a variety of crops to promote flower development and fruit growth. This, in turn, increases crop yields.

The effect of three different auxins, IBA, IAA, and NAA, on root formation in Camellia sinensis was investigated in order to determine the relative effect of each auxin on root formation. According to the results for the species, IBA produced a higher root yield than the other auxins. IBA's effect is consistent with other studies in which IBA is the most commonly used auxin for root formation.

Indole-3-butyric acid-containing products were traditionally used to protect plants during transplantation by stimulating root growth and decreasing shock.

Plant Tissue Culture

Indole-3-butyric acid and other auxins are used in plant tissue culture to initiate root formation in vitro in a process known as micropropagation. Plant micropropagation is the process of growing differentiated or undifferentiated cells from explants. Explants are small samples of plants. In conjunction with cytokinins such as kinetin, auxins such as IBA can be used to induce the formation of callus, which are masses of undifferentiated cells. Callus formation is frequently used as a first step in micropropagation, where callus cells are then caused to form other tissues such as roots by exposing them to hormones that produce roots, such as auxins. The process of callus to root formation is known as indirect organogenesis, whereas direct organogenesis occurs when roots form directly from the explant.

Why Indole-3-butyric acid is used?

The relative stabilities of IAA and IBA were determined using various tissue culture procedures. IBA was significantly more stable for autoclaving than IAA. Under growth chamber conditions, IBA was also found to be more stable than IAA in liquid Murashige and Skoog medium (MS). In agar-solidified Murashige and Skoog medium, the stabilities of IBA and IAA were comparable. These findings have important implications for IBA and IAA preparation, storage, and handling in plant tissue culture.

Commercial Indole-3-butyric acid

Although it was thought that Indole-3-butyric acid was entirely synthetic, it has been reported that it was isolated from the leaves and seeds of maize and other species. It has been demonstrated to be synthesised in vivo in maize using IAA and other compounds as precursors. This chemical can also be extracted from any species of Salix (Willow).

Because Indole-3-butyric acid is not completely soluble in water, it is usually dissolved in 75% or purer alcohol for use in plant rooting, yielding a solution with a concentration of 10,000 to 50,000 ppm. This alcohol solution is then diluted to the desired concentration with distilled water.

Product For Successful Results

Indole-3-butyric acid is a white to light-yellow crystalline solid with the molecular formula C12H13NO2. It melts at 125 °C under atmospheric pressure and decomposes before boiling.
