“…In summary, the stress encountered determines the events following it, and the treatment with BABA can potentiate (prime) the most appropriate to counteract it 3,4 . For example, bacterial infection by Pseudomonas syringae pv tomato ( Pst ) DC3000 and attack by the fungal pathogen Botrytis cinerea are both combatted through potentiation of salicylic acid (SA)-dependent defenses, 5,6 while defense against Plectosphaerella cucumerina is obtained through an enhanced callose deposition depending on a functional abscisic acid (ABA) signaling pathway 7 .…”

The capacity of β-aminobutyric acid (BABA) to induce resistance in plants against biotic and abiotic stresses has been known for more than 50 y. In the beginning reports were mainly descriptive of the phenomenon, but it became clear with the discovery of BABA insensitive mutants in Arabidopsis that there was definitely a genetic basis underlying BABA-induced resistance. The study of these mutants, along with the use of regular hormone mutants, allowed establishing the defense pathways activated upon defense induction. To date it is clear that BABA potentiates the defense pathway more appropriate to counteract the upcoming stress situation, through a phenomenon termed priming. Interestingly, plants possess a receptor for BABA, but up to recently there was a general consensus on the fact that BABA was a xenobiotic molecule. The development of an accurate non-destructive assay for measuring aminobutyric acid isomers in planta and the finding of plant-produced BABA, thus seems to represent the missing link for the discovery of a novel plant hormone. Differences and similarities with some of the classical plant hormones are presented here.

“…BABA does not usually induce directly defense responses, but primes the plant to react faster and/or stronger to a given stress 3 . Interestingly, the priming state induced by BABA can also be transmitted to the descendants of a plant via its seeds 9 …”

“…Priming and underlying mechanisms of action in various induced resistance phenomena in plants have been widely described (Balmer et al, 2015;Conrath et al, 2015). Among the synthetic chemical priming agents, the nonproteinogenic amino acid b-aminobutyric acid (BABA) has a special place owing to its very broad range of action (Baccelli & Mauch-Mani, 2016). Priming by BABA leads to augmented biotic and abiotic stress resistance through the potentiation of the signaling pathway most appropriate to counteract the given stress situation (Zimmerli et al, 2000).…”

The defense system of a plant can be primed for increased defense, resulting in an augmented stress resistance and/or tolerance. Priming can be triggered by biotic and abiotic stimuli, as well as by chemicals such as β-aminobutyric acid (BABA), a nonprotein amino acid considered so far a xenobiotic. Since the perception mechanism of BABA has been recently identified in Arabidopsis thaliana, in the present study we explored the possibility that plants do synthesize BABA. After developing a reliable method to detect and quantify BABA in plant tissues, and unequivocally separate it from its two isomers α- and γ-aminobutyric acid, we measured BABA levels in stressed and nonstressed A. thaliana plants, and in different plant species. We show that BABA is a natural product of plants and that the endogenous levels of BABA increase rapidly after infection with necrotrophic, biotrophic and hemibiotrophic pathogens, as well as after salt stress and submergence. Our results place the rise in endogenous BABA levels to a point of convergence in plant stress response and provide biological significance to the presence of a receptor in plants. These findings can explain the extremely widespread efficacy of BABA and open the way to unravel the early steps of priming.

“…Priming can be maintained during the whole life cycle of the plant and can even be transmitted to following generations, therefore representing an immunological memory of the plant (Mauch‐Mani, Baccelli, Luna, & Flors, ). Priming can be triggered by a wide range of synthetic elicitors including SA analogues such as benzo (1,2,3‐thiadiazole‐7‐carbothioic acid‐S‐methyl ester (BTH) (Cools & Ishii, ; Deepak, Ishii, & Park, ; Kohler, Schwindling, & Conrath, ; Faize, Faize, & Ishii, ) as well as 2,6‐dichloroisonicotinic acid (Chandrashekar & Umesha, ) and β‐aminobutyric acid (BABA) (Baccelli & Mauch‐Mani, ).…”

Extracts from the brown seaweeds Cystoseira myriophylloides, Laminaria digitata and Fucus spiralis were evaluated as plant defence inducers against the wild fire disease of Nicotiana benthamiana. Seeds’ imbibition in aqueous seaweed extracts (SE) results in plants with reduced disease severity. In addition, bacterial populations were significantly reduced in these plants when compared to those germinated in sterile distilled water. They primed N. benthamiana for H2O2 accumulation and for enhanced activity of several antioxidant enzymes including catalase, ascorbate peroxidase, guaiacol peroxidase and polyphenol oxidase. These results revealed that soaking of seeds in SE before sowing allows N. benthamiana to reduce pathogen attack and can be easily applied in practice.
