Alpha-Aminobutyric acid

Aminobutyric acid (ABA) is a non-protein amino acid that can protect certain plants from pathogens.

Chemical Formula: C4H9N1O2
Other names: alpha-n-Butyric acid
Layman's explanation: Aminobutyric acid (ABA), when introduced onto Arabidopis plants, has the ability to induce resistance to certain pathogens. ABA protects these plants against pathogens through activation of natural defense mechanisms of the plant, such as callose deposition, the hypersensitive response (HR), and the formation of trailing necroses. The induced resistance is often associated with a process called priming, which is an increased capacity to mobilize cellular defense responses. The process of priming also occurred in grapevine plants (Vitis vinifera) in order to build resistance against downy mildew.
Keywords: callose, priming
