“…Moreover, POD was activated more rapidly than phenolic compound accumulation in all the treated plantlets (Figures 1 to 3). These results were in agreement with the previous reports that PODs are involved in polymerization of phenolics, and synthesis of phenolic compounds in relation to plant defense responses against infection and wounding (Bruce and West 1989;Deborah et al 2001;Egea et al 2001;Gayoso et al 2010;Lagrimini 1991;Morkunas and Gmerek 2007). However, B. platyphylla var.…”

This study investigated the time-course changes of the in situ peroxidase (POD) distribution and expression of POD isozymes in Betula platyphylla var. japonica plantlet No. 8 infected with a canker-rot fungus, Inonotus obliquus strain IO-U1. Intact (C1), wounded (C2), and infected (T) plantlets were collected at 2 h up to 30 d. In situ POD activity was detected in the C2 and T plantlets, and the POD activity in the T plantlets was more widely distributed compared to the C2 plantlets. In addition, the area of POD activity localization was almost the same as that of phenolic compounds, although a time lag was found between the appearance of POD activity and phenolic compounds. POD isozymes were clearly detected within the basic range (pI>8.5) in isoelectric focusing electropherograms. The activity of cationic POD isozymes in the C2 and T plantlets was induced strongly compared to the C1 plantlets. In addition, the pattern of time-course changes in the activities of in situ POD and POD isozymes was different between the C2 and T plantlets, suggesting that the responsive mechanisms against fungal infection are different from the responses to wounding. The obtained results suggest that cationic POD isozymes are related to the basal resistance in B. platyphylla var. japonica plantlet No.8 against infection with I. obliquus strain IO-U1.

“…According to Hammerschmidt (1984), an effective inhibition of an infection caused by necrotrophs is possible only if lignin synthesis is induced shortly after inoculation. In embryo axes of lupine supplemented with sugar the content of lignins as early as 24 h after inoculation with Fusarium oxysporum was twofold greater than that in non-supplemented embryos, although even the latter showed an increased lignin level after infection (Morkunas and Gmerek 2007). In addition, it was shown that sugar-supplemented embryos had a greater activity of peroxidases covalently and ionically bound with the cell wall ).…”

“…At the infection sites sugars are taken up by the attacking fungus, while the attacked plant tissues have high substrate requirements for the initiation of defense responses, e.g., the synthesis of pathogenesis-related (PR) proteins, phenylpropanoids, or papillum formation (Strömberg and Brishammar 1993;Morkunas et al 2005Morkunas and Gmerek 2007;Bolton 2009). It has been shown that the induction of defense is cost intensive (Swarbrick et al 2006).…”

“…Thus, various antioxidant enzymes such as peroxidase (POX), superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) participate in the ROS metabolism during pathogen attacks. POX was found to be one of the components of the defence systems that are stimulated in plants in response to infection by pathogens such as Fusarium oxysporum (Morkunas and Gmerek, 2007). It was reported that Fusarium infection resulted in the increased activity of antioxidant enzymes together with increased levels of ROS and lipid peroxidation in cucumber roots (Ye et al, 2006;El-Khallal, 2007;Mandal et al, 2008).…”

Inoculating wheat (cv. Giza 164) with various Fusarium species had different effects on the catalase (CAT), peroxidase (POX) and ascorbate peroxidase (APX) activity in different plant tissues. The CAT activity induced in the shoots of wheat plants by some pathogens (F. merismoides, F. moniliforme, F. poae and F. sambucinum) was relatively higher than that induced by other pathogens. The results showed an increase in POX activity in infected shoots except those inoculated with F. sambucinum, where the POX activity decreased. Inoculating wheat plants with individual Fusarium species or with a mixture of pathogens caused an increase in APX in the shoots, except for those treated with F. poae, where the APX activity decreased. The activity of these antioxidant enzymes thus increased in most cases in the shoot system of wheat plants under Fusarium infection. Investigations on the metabolic activity of wheat plants inouculated with individual Fusarium species or with a mixture of pathogens showed higher contents of all the protein fractions, soluble sugars, total free amino acids and proline. The K + and Ca 2+concentrations decreased to various extents in different cases. The Na + content increased in wheat shoots, especially after inoculation with F. merismoides. The results signify that the most serious infection was caused by F. culmorum, F. graminearum and F. oxysporum and by a mixture of all the Fusarium species.
