Abstract
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.

BABA-induced resistance against late quantitative proteomic analysis of the apoplast secretome. They showed that several processes that blight, Bengtsson et al, developed an original approach based on a transcript analysis in combination were related to plant hormones and amino-acid metabolisms were affected, in addition to genes with quantitative proteomic analysis of the apoplast secretome
Summary
Increasing demand for environmentally-friendly alternatives to traditional pesticides is an impetus for designing new biological strategies for crop protection. SAR is considered as the most agronomically relevant type of plant immunity [6] and can be triggered by signal molecules that are involved in plant resistance to pathogens, including SA and a wide range of synthetic compounds Among these compounds functional analogues of SA are able to activate plant defense responses and provide attractive alternatives to conventional biocidal. They are able to mimic a subset of known SA functions by directly interfering with its receptors or by triggering transcriptional and physiological responses that are related to those induced by SA without directly interfering with SA targets [9] They generally do not possess antimicrobial activity in vitro and can activate resistance against broad spectra of pathogens by inducing SAR genes that are triggered by biological or SA inducers they are many problems that growers must consider during their use in crop protection, including incomplete disease reduction and the fitness cost for plants [10]. These new agrochemicals will provide resistance against a broader spectrum of plant pathogens, but may contribute to the identification of novel pathway components of SAR
