“…p-Aminobenzoic acid (PABA) (a folate precursor) has also been effective in eliciting induced resistance (Song et al 2013). This implies a big potential for crop protection against pathogens by vitamin treatments, due to its safety and cost effectiveness (Lyon 2007).…”

Vitamins are essential organic compounds for humans, having lost the ability to de novo synthesize them. Hence, they represent dietary requirements, which are covered by plants as the main dietary source of most vitamins (through food or livestock's feed). Most vitamins synthesized by plants present amino acids as precursors (B1, B2, B3, B5, B7, B9 and E) and are therefore linked to plant nitrogen metabolism. Amino acids play different roles in their biosynthesis and metabolism, either incorporated into the backbone of the vitamin or as amino, sulfur or one-carbon group donors. There is a high natural variation in vitamin contents in crops and its exploitation through breeding, metabolic engineering and agronomic practices can enhance their nutritional quality. While the underlying biochemical roles of vitamins as cosubstrates or cofactors are usually common for most eukaryotes, the impact of vitamins B and E in metabolism and physiology can be quite different on plants and animals. Here, we first aim at giving an overview of the biosynthesis of amino acid-derived vitamins in plants, with a particular focus on how this knowledge can be exploited to increase vitamin contents in crops. Second, we will focus on the functions of these vitamins in both plants and animals (and humans in particular), to unravel common and specific roles for vitamins in evolutionary distant organisms, in which these amino acid-derived vitamins play, however, an essential role.

“…For instance, Para-aminobenzoic acid (PABA), which is a cyclic amino acid that belongs to the vitamin B group, was able to induce SAR in pepper against cucumber mosaic virus (CMV) and Xanthomonas axonopodis pv. vesicatoria through SA pathway [58]. The substituted benzoates, 3-chlorobenzoic acid and 3,5-dichlorobenzoic acid induced basal defense against H. parasitica in A. thaliana [54].…”

Functional Analogues of Salicylic Acid and Their Use in Crop Protection

Functional analogues of salicylic acid are able to activate plant defense responses and provide attractive alternatives to conventional biocidal agrochemicals. However, there are many problems that growers must consider during their use in crop protection, including incomplete disease reduction and the fitness cost for plants. High-throughput screening methods of chemical libraries allowed the identification of new compounds that do not affect plant growth, and whose mechanisms of action are based on priming of plant defenses, rather than on their direct activation. Some of these new compounds may also contribute to the discovery of unknown components of the plant immune system.

“…Well characterised chemicals, such as BABA, have been demonstrated to enhance resistance by priming of defence mechanisms in the field and in some cases their action also provided a synergistic effect in combination with the use of pesticides (Cohen, 2002). Importantly, the folate precursor para-aminobenzoic acid (PABA) has been successful in inducing resistance against viruses and citrus canker disease caused by Xanthomonas axonopodis, and its use resulted in an increase in yield (Song et al, 2013). Therefore, the scientific community is embracing the idea of investigating whether priming plants for defence could offer a new strategy for pest and disease control.…”
