“…Stimulation of ethylene production by D-isomers of severa1 amino acids has been reported by Satoh and Esashi (1980b) in various cocklebur seed tissues. Similarly, Cohen et al (1994) reported that a-and P-aminobutyric acid, but not GABA, can stimulate ethylene production in tomato plants. Thus, our results suggest that the ability of GABA to stimulate ethylene production might differ in various plant species.…”

y-Aminobutyric acid (GABA), a nonprotein amino acid, is often accumulated in plants following environmental stimuli that can also cause ethylene production. We have investigated the relationship between GABA and ethylene production in excised sunflower (Helianfhus annuus 1.) tissues. Exogenous GABA causes up to a 14-fold increase in the ethylene production rate after about 1 2 h. Cotyledons fed with [14C]GABA did not release substantiaf amounts of radioactive ethylene despite its chemical similarity to 1-aminocyclopropane-1-carboxylic acid (ACC), indicating that GABA is not likely to be an alternative precursor for ethylene.GABA causes increases in ACC synthase mRNA accumulation, ACC levels, ACC oxidase mRNA levels, and in vitro ACC oxidase activity. In the presence of aminoethoxyvinylglycine or a-aminoisobutyric acid, GABA did not stimulate ethylene production. We therefore conclude that GABA stimulates ethylene biosynthesis mainly by promoting ACC synthase transcript abundance. Possible roles of GABA as a signal transducer are suggested.

“…Application of BABA as a foliar spray is one of the most common application methods in laboratory and field conditions. The optimized concentration of 10 mM BABA used in this study was chosen to overcome possible side effects on treated plants manifested as hypersensitive response (HR)-like lesions with subsequent leaf wilting (Cohen et al, 1994;Siegriest et al, 2000;Bengtsson et al, 2014a). During testing of the optimal BABA concentrations on the two tomato genotypes, an interesting phenomenon was observed.…”

“…Unlike its isomers a-and c-aminobutyric acid, BABA induces resistance in many plants against various pathogens (Pie R knaGrochala and Ke R pczynska, 2013). For instance, BABA induces a strong resistance of tomato towards the tomato late blight Phytophthora infestans (Cohen et al, 1994;Cohen, 2002) and to root-knot nematodes (Oka and Cohen, 2001). However, it has been observed that BABA treatment can undesirably affect plant growth, thus hindering its use for field applications (Wu et al, 2010).…”

Background and Aims Current strategies for increased crop protection of susceptible tomato plants against pathogen infections include treatment with synthetic chemicals, application of natural pathogen-derived compounds or transfer of resistance genes from wild tomato species within breeding programmes. In this study, a series of 45 genes potentially involved in defence mechanisms was retrieved from the genome sequence of inbred reference tomato cultivar Solanum lycopersicum 'Heinz 1706'. The aim of the study was to analyse expression of these selected genes in wild and cultivated tomato plants contrasting in resistance to the biotrophic pathogen Oidium neolycopersici, the causative agent of powdery mildew. Plants were treated either solely with potential resistance inducers or by inducers together with the pathogen.Methods The resistance against O. neolycopersici infection as well as RT-PCR-based analysis of gene expression in response to the oomycete elicitor oligandrin and chemical agent b-aminobutyric acid (BABA) were investigated in the highly susceptible domesticated inbred genotype Solanum lycopersicum 'Amateur' and resistant wild genotype Solanum habrochaites.Key Results Differences in basal expression levels of defensins, germins, b-1,3-glucanases, heveins, chitinases, osmotins and PR1 proteins in non-infected and non-elicited plants were observed between the highly resistant and susceptible genotypes. Moreover, these defence genes showed an extensive up-regulation following O. neolycopersici infection in both genotypes. Application of BABA and elicitin induced expression of multiple defence-related transcripts and, through different mechanisms, enhanced resistance against powdery mildew in the susceptible tomato genotype.Conclusions The results indicate that non-specific resistance in the resistant genotype S. habrochaites resulted from high basal levels of transcripts with proven roles in defence processes. In the susceptible genotype S. lycopersicum 'Amateur', oligandrin-and BABA-induced resistance involved different signalling pathways, with BABAtreated leaves displaying direct activation of the ethylene-dependent signalling pathway, in contrast to previously reported jasmonic acid-mediated signalling for elicitins.

“…In plants, GABA is produced as a response to stress (20), and treatments with BABA were shown to provide protection against various pathogens (21)(22)(23). However, little is known concerning the mode of action of BABA; some studies report an induction of PR after BABA treatment (24), whereas others state the contrary (25). Thus, the mode of action of BABA remains a matter of controversy.…”

The nonprotein amino acids ␥-aminobutyric acid (GABA) and ␤-aminobutyric acid (BABA) have known biological effects in animals and plants. Their mode of action has been the object of thorough research in animals but remains unclear in plants. Our objective was to study the mode of action of BABA in the protection of Arabidopis plants against virulent pathogens. BABA protected Arabidopsis against the oomycete pathogen Peronospora parasitica through activation of natural defense mechanisms of the plant such as callose deposition, the hypersensitive response, and the formation of trailing necroses. BABA was still fully protective against P. parasitica in transgenic plants or mutants impaired in the salicylic acid, jasmonic acid, and ethylene signaling pathways. Treatment with BABA did not induce the accumulation of mRNA of the systemic acquired resistance (SAR)-associated PR-1 and the ethylene-and jasmonic acid-dependent PDF1.2 genes. However, BABA potentiated the accumulation of PR-1 mRNA after attack by virulent pathogenic bacteria. As a result, BABA-treated Arabidopsis plants were less diseased compared with the untreated control. In the case of bacteria, BABA protected mutants insensitive to jasmonic acid and ethylene but was not active in plants impaired in the SAR transduction pathway. Thus, BABA protects Arabidopsis against different virulent pathogens by potentiating pathogenspecific plant resistance mechanisms. In addition, we provide evidence that BABA-mediated papilla formation after P. parasitica infection is independent of the SAR signaling pathway.
