Plants are continuously exposed to the attack of invasive microorganisms, such as fungi
or bacteria, and also viruses. To fight these attackers, plants develop different metabolic
and genetic responses whose final outcome is the production of toxic compounds that
kill the pathogen or deter its growth or semiotic molecules that alert other individuals of
the same plant species. These molecules are derived from the secondary metabolism and
their production is induced upon detection of a pathogen-associated molecular pattern
(PAMP). These PAMPs are different molecules that are perceived by the host cell
triggering defense responses. PAMP-elicited compounds are highly diverse and specific
of every plant species and can be divided into preformed metabolites or phytoanticipins
that are converted into toxic molecules upon pathogen perception, and toxic metabolites
or phytoalexins that are produced only upon pathogen attack. Moreover, plant volatile
emissions are also modified in response to pathogen attack to alert neighboring
individuals or to make plants less attractive to pathogen vector arthropods. Plant
metabolite profiling techniques have allowed the identification of novel antimicrobial
molecules that are induced upon elicitation. However, more studies are required to
assess the specific function of metabolites or metabolite blends on plant-microbe
interactions. [-]
