However, this did not translate into an increased resistance to F. graminearum or C. graminicola, the authors suggesting potential lack of bioavailability or inappropriate localisation that may be corrected by up or down-regulation of other genes involved in the pathway. Despite this, the author’s are of the opinion that metabolic engineering of terpenoid metabolism in maize still has potential as the transgenic plants were of normal phenotype unlike previous attempts at terpenoid engineering in tomato, arabidopsis and potato [50-52]. 4. Flavonoids (Proanthocyanidins, Anthocyanins, Flavonols,

Isolflavonoids) Flavonoids Inhibitors,research,lifescience,medical are a large class of phytoanticipan and phytoalexin phenolic metabolites synthesised from phenylalanine in the Inhibitors,research,lifescience,medical shikimate pathway (Figure 1) and includes the flavonols, flavones, flavanones, anthocyanidins, proanthocyanidins and chalcones. Flavonoids play an extensive role in many plant processes such as signalling; antioxidant activity, feeding deterrents, antimicrobial activity, UV protection, male fertility

and flower pigmentation [53-55]. Flavonoids have received a significant amount of interest due to their potential uses in the pharmaceutical industry due to their anti-inflammatory and Inhibitors,research,lifescience,medical anticancer properties [56], however flavonoids also play numerous important roles in plant resistance, defence, signalling and symbiosis [57]. A number of mechanisms of antimicrobial action have been hypothesised for flavonoids including the crosslinking of microbial enzymes, inhibition of cellulases and other microbial enzymes, chelation of metals necessary for microbial enzyme activity and polymerisation Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical into crystalline structures

which may act as a physical barrier during pathogen attack [58]. A number of preformed flavonoids (phytoanticipans) belonging to the anthacyanidin class inhibit the growth and spore germination of the fungal and bacterial pathogens of rice M. grisea and Xanthomonas oryzae [59].

These secondary metabolites inhibit fungal growth in vitro new and are induced during the initial stages of infection only in cells in direct contact with the fungus. The flavonoid sakuranetin (Figure 1) was identified using LC-MS to be induced following treatment of rice with the fungal elicitor chitosan [61]. Proanthocyanidins have been demonstrated to play a part in defence against Fusarium species through suggested mechanisms such as chelation of metals required for enzymatic activity, formation of a physical barrier, inhibition of cellulases and crosslinking of microbial enzymes [58].
