β-Aminobutyric acid (BABA) is an isomer of the amino acid aminobutyric acid with chemical formula C4H9NO2. It has two isomers, gamma-aminobutyric acid (GABA) and alpha-aminobutyric acid. All three are non-proteinogenic amino acids, not being found in protein. BABA is known for its ability to induce plant disease resistance, as well as increased resistance to abiotic stresses, when applied to plants.

Plant disease resistance

BABA was first noticed to increase the resistance of plants to disease in 1960, when it was observed that it decreased late blight of tomato. Further tests were made in the 1960s, but it was not until the 1990s that interest in the compound was renewed.[1] Since then, it has been shown to be effective in many different pathosystems under controlled conditions. Both perennial and annual plants have been shown to respond, as well as both monocot and dicot plants in the Solanaceae, Cucurbitaceae, Compositae, Fabaceae, Brassicaceae, Graminae, Malvaceae, Rosaceae, and Vitaceae families. Pathogen groups that have shown a response include viruses, bacteria, nematodes, fungi and oomycetes.[1]

Rather than having a direct effect on plant pathogens, it activates plant immune systems enabling them to resist infection more effectively. The effects that it has been studied extensively using the model plant Arabidopsis thaliana.[1]

Mode of action

BABA induces defense responses in plants by both physical and biochemical means. The precise mechanism depends on the plant and pathogen species.[1]

Heritability

A paper published in 2012 found that the offspring of Arabidopsis plants treated with BABA were more resistant to infection by Pseudomonas syringae.[2] An editorial in Plant Physiology suggested that this must be due to epigenetic inheritance.[3]
