“…Phytoalexins have a crucial role in plant defense against pathogens. Camalexin (Tsuji et al, 1992;Glazebrook and Ausubel, 1994) and rapalexin A (Pedras and Adio, 2008;Ahuja et al, 2012) are known to be phytoalexins of Arabidopsis. The biosynthesis pathway and the related enzymes of camalexin have been well characterized (Ahuja et al, 2012).…”

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.

Plant secondary or "specialized" metabolites play an important role in plant survival, often as defense chemicals, and are the predominant natural sources of drugs for human health because of their chemical diversity and biosynthetic complexity. As a consequence, the biosynthesis and regulation of plant specialized metabolism have been intensively studied in a number of model and non-model plant species. Here, we review what is currently known about the transcriptional regulators and pathway enzymes that contribute to the chemical diversity and biosynthetic complexity of two of the three major groups of plant specialized metabolites, the phenylpropanoids and the nitrogen-containing alkaloids. For the latter, we will focus on aromatic amino acid-derived alkaloids that have been extensively studied for their regulation and biosynthesis. They include the amine-derived terpenoid indole alkaloids, the free indole-derived benzoxazinoids, and the oximederived aromatic compounds, such as the tyrosine-derived cyanogenic glycosides, indole glucosinolates, and sulfur-containing indole alkaloids. In addition, we will discuss the possible phylogenetic conservation of the transcriptional regulators of phenylpropanoid metabolism in defense. Keywords
