Application

Indole-3-butyric acid (IBA) has been used as a standard to monitor IBA in urine samples by tandem mass spectrometry-selected reaction monitoring (SRM) and Ultra-high performance liquid chromatography (UHPLC), as a standard for high performance liquid chromatography (HPLC) for the quantification of IBA in foliar tissues of Coffea canephora seedlings.

Biochem/physiol Actions

Indole-3-butyric acid (IBA) is a naturally occurring phytohormone auxin (plant growth regulator). It promotes root formation in cuttings but does not affect ethylene levels. IBA might be a precursor for indole-3-acetic acid (IAA) through β oxidation pathway. IBA is present in plant species like Zea mays, Pisum sativum and Arabidopsis. IBA is more potent than IAA for inducing root formation.

Abscisic acid (ABA) is a ubiquitous phytohormone involved in many developmental processes and stress responses of plants. ABA moves within the plant, and intracellular receptors for ABA have been recently identified; however, no ABA transporter has been described to date.

While over 10% of the human metabolome is directly associated with the gut microbial metabolism, specific metabolites are largely uncharacterized. Therefore, methods for the identification and quantification of microbiota-associated metabolites in biological fluids such as urine or plasma are necessary

Light-grown mung bean (Phaseolus aureus Roxb.) cuttings were treated with buffered and nonbuffered solutions of Ethephon, indole butyric acid (IBA), and the combination of both. Ethephon treatment resulted in increased tissue ethylene levels with increasing solution pH, but had no
