“…PAL catalyzes the first step of the phenylpropanoids pathway by which L-phenylalanine is deaminated to trans-cinnamic acid and is considered as an important regulation point between primary and secondary metabolism (Dixon & Paiva 1995). Plants respond to stresses through activating an array of defense mechanisms such as reactive oxygen species formation which is scavenged by production of phenolic compounds with antioxidant properties (Mishra et al 2012;Shaheen et al 2013). In our study, total phenolics, falvonoids, and flavonols were increased in response to the culture filtrate.…”

Cell suspension cultures of Linum album Kotschy ex Boiss. have been reported to produce anticancer podophyllotoxin and its related lignans. In the present study, we investigated the effect of culture filtrate of Fusarium graminearumon growth, and lignan and phenolic compounds in L. album cell culture. After 7 days of pre-culture, the cells were treated with 1% (v/v) of the culture filtrate. Cell growth was reduced, while phodophyllotoxin and lariciresinol production was stimulated reaching a maximum 0.0187 mg/g fresh weight (FW) and 0.0136 mg/g FW 5 days after the treatment, respectively. Also, our results provide evidence that the culture filtrate of F. graminearum can be effective on phenylalanine ammonia-lyase activity and phenolic compounds.

“…This phenomenon is elucidated by the presence of resistance genes in the host (H) and avirulence genes (Avr) in nematodes; the interaction between these genes triggers a cascade of plant defense responses (Fuller et al, 2008). The HR is initially triggered by the production of reactive oxygen species (ROS) (Mishra et al, 2012); it is followed by other molecular events such as the accumulation of salicylic acid, nitric oxide and different intracellular calcium levels (Muret et al, 2008). Such accumulation results in the localized and rapid death of cells composing the feeding site or of cells adjacent to it (Williamson, 1999), fact that is common in different associations between plants and nematodes (Branch et al, 2004;Anthony et al, 2005;Motta et al, 2012).…”

One of the main phytonematode control alternatives is the use of antagonistic plants in crop rotation or succession systems. Although java legume shows antagonist potential to control Meloidogyne javanica, its reaction to other nematodes was not investigated so far. Thus, the aim of the current study is to assess the penetration and reproduction factor (RF) of M. incognita, Rotylenchulus reniformis and Pratylenchus brachyurus in java, using soybean as control. Plants individually inoculated with 1000 specimens from each nematode were assessed 5, 10, 15, 20, 25 and 30 days after inoculation (DAI) for nematode penetration and development. The RF was assessed under two inoculum levels of each nematode (1000 and 700 specimens) 60 days after inoculation, for M. incognita and R. reniformis; and 80 days after inoculation, for P. brachyurus. Meloidogyne incognita and R. reniformis showed lower penetration and reproduction in java (RF < 1), whereas P. brachyurus showed higher penetration and RF > 1. Thus, the java legume can be considered resistant to M. incognita and R. reniformis, as well as susceptible to P. brachyurus.

“…infestation had a typical local hypersensitive response (HR) nature. Reactive oxygen species were generated during earlier HR events in response to some aphid species (Thompson & Goggin 2006;Mishra et al 2012). Cereal aphids S. avenae and R. padi also induced oxidative stress in triticale tissues that was especially strong within less susceptible cultivar (Łukasik et al 2012).…”

Changes in the activity of lysine decarboxylase (LDC), tyrosine decarboxylase (TyDC), and ornithine decarboxylase (ODC) within orchid (Phalaenopsis × hybridum 'Innocence') leaves, infested by two mealybug species: Pseudococcus longispinus (Targ. Tozz.) and Pseudococcus maritimus (Ehrh.) were quantified. The pattern of changes was dependent on the insect species and duration of infestation. P. longispinus feeding increased LDC and TyDC activity after one week during the total period of observations. This species inhibited ODC activity after one week but increased later. P. maritimus decreased LDC activity in orchid leaves at all studied terms. TyDC action also went up during the first week of the infestation and was reduced after two weeks, while ODC was decreased after one day and induced later. The mechanism for the participation of analysed amino acid decarboxylases in local and/or systemic steps of orchid responses to mealybug infestation is discussed.
