“…Similarly, a strong defensive reaction based on phenolic compounds accumulation and callose deposition was observed in regions invaded by pathogen and in adjacent cells of barley infected by B. graminis compared to noninvaded regions in the study by Swarbrick et al (2006). By contrast, no relationship between the soluble phenolics content and PAL activity was reported by Olenichenko and Zagoskina (2005) in wheat and by Pociecha et al (2009) in festulolium where no correlation was detected between the PAL activity and soluble phenolic in reaction to cold. It is possible that in some cases phenolic monomers inhibit PAL and for that reason PAL activity is not related to production of phenolic compounds (Olenichenko & Zagoskina 2005).…”

The beneficial effects of trans-resveratrol on pathogen-response and its physiological mechanisms were studied in two wheat cultivars differing in the level of resistance against powdery mildew (Blumeria graminis (DC.) Speer). Resveratrol induced phenolics metabolism in a manner that lead to increased phenylalanine ammonia-lyase (PAL) and β-D-glucosidase activity in leaf regions showing no symptoms of pathogen infection. In less-resistant cultivar, similar alterations were additionally observed in regions invaded by the pathogen. Resveratrol also stimulated photosynthetic efficiency during pathogenesis and this effect was more prominent in the resistant cultivar. Regulatory function of resveratrol on wheat growth and development was also observed (stimulation of generative induction). High performance liquid chromatography (HPLC) analysis detected a low amount of compound with retention time corresponding to trans-resveratrol in healthy leaves and increased the content of this compound in infected foliage. The multidirectional properties of resveratrol activity in wheat plants are discussed.

“…Levels of lignin and soluble phenols were closely related in leaves and roots of Triticum aestivum plants at 2 °C (Olenichenko and Zagoskina 2005). While leaves showed an increase of soluble phenols and a decrease of lignin, the opposite was observed in roots.…”

Lignin is a polymer of phenylpropanoid compounds formed through a complex biosynthesis route, represented by a metabolic grid for which most of the genes involved have been sequenced in several plants, mainly in the model-plants Arabidopsis thaliana and Populus. Plants are exposed to different stresses, which may change lignin content and composition. In many cases, particularly for plant-microbe interactions, this has been suggested as defence responses of plants to the stress. Thus, understanding how a stressor modulates expression of the genes related with lignin biosynthesis may allow us to develop study-models to increase our knowledge on the metabolic control of lignin deposition in the cell wall. This review focuses on recent literature reporting on the main types of abiotic and biotic stresses that alter the biosynthesis of lignin in plants.Moura JCMS, Bonine CAV, Viana JOF, Dornelas MC, Mazzafera P (2010) Abiotic and biotic stresses and changes in the lignin content and composition in plants.

“…It was of interest that the level of PAL activity remained at the level of control in seedlings treated preliminarily with exometabolites of the strain IMV B-7404 after the leaves were infected with phytopathogen. It is known that the catalytic potential of PAL in many plants (including monocotyledonous) is much higher than it is required for synthesis of polyphenols [17]. That is why even short-term activation of PAL is sufficient for accumulating a necessary pool of phenol compounds in seedlings [18].…”

Influence of Bacillus amyloliquefaciens subsp. plantarum IMV B-7404 strain exometabolites on phenylalanine ammonia-lyase (PaL, eC 4.3.1.24) A erobic spore-forming bacteria of Bacillus genus are considered as perspective agents of biological control, since they are antagonists to numerous phytopathogenic fungi and bacteria owing to synthesis of a broad range of secondary metabolites with expressed bactericidal and fungicidal properties [1]. One should note not only antibiotic substances among Bacillus genus bacteria exometabolites but also compounds characterized by phytostimulating and immunomodulating activity. The latter, in its turn, determines the expediency of using the Bacillus strains when creating efficient biological preparations of broad-range effect for plant growing needs [2].Bacillus amyloliquefaciens subsp. plantarum IMB B-7404 strain with antifungal activity as to phytopathogens Fusarium graminearum and Bipolaris sorokiniana [3] was selected by the results of screening conducted by the authors. The nature of IMB B-7404 strain exometabolites, which determines its phytostimulating and antagonistic activity [4,5], was studied. Using MALDI-TOF mass-spectrometry and molecular genetic methods of analysis, it was also established that lipopeptide antibiotic exometabolites of the studied strain belonged to the family of fengicins [6].Phytoimmunity development is a complex biochemical process induced by stress factors of biotic and abiotic nature. It is known that activation of phenol metabolism and, in particular, an increase of activity of the basic anti-stress enzymes -phenylalanine ammonia-lyase (PAL, EC 4.3.1.24) and peroxidase is one of defense responses of plants to the effect of stressors. The enzyme PAL is one of recognized biochemical markers of the induced plant resistance both to diseases caused by phytopathogens and to the effect of various stressor factors of biotic and abiotic nature. PAL performs deamination of phenylalanine with formation of trans-cinnamic acid and ammonia, takes part in synthesis of salicylic acid precursors, phytoalexins, lignin monomers, which strengthen mechanical and chemical barriers of plant cells and thus prevent their infection by phytopathogenic fungi [7,8]. PAL activity can change depending on the phase of plant development, its genotype and external conditions [9]. The work [10], where the enzyme activity was depressed by specific inhibitors, evidences for the important role of PAL in phytoimmunity induction. Under treatment by these inhibitors, the pathogenic lesion increased even in genetically resistant plants, as a result of the cessation of forming phenols and lignin precursors.
