“…The products of PAL and TAL are modulated via phenylpropanoid metabolism to precursors of secondary metabolites containing flavonoid pigments and phytoalexins Ahmedet al (2016). Moreover, our results regarding Put treatments were in line with Mandal et al (2013), they documented that total phenolics and flavonoids content increased in Salvinia natans plant under exogenous application of Put (1mM) and 100µM H 2 O 2 as an indirect stressor for establishment of oxidative damage compared with the highest dose of H 2 O 2 (100µM)only without Put treatment. This increase may be ascribe to polyamine has been in regulation H 2 O 2 generation plants, since H 2 O 2 is generally one of decomposition products from Put oxidation by di-amine oxidase catalyzed by Cu Ao during stress conditions Zabihi et al (2014), Li et al(2015) which in turn activation of phenolic synthesis as potential agents in scavenging activity of ROS.…”

A STUDY was conducted on one-year old sour orange seedlings in long term experiment during 2014 and 2015, held in greenhouse of EL-Maamora station, Horticulture Research Institute. The aim of trial was to evaluate foliar chitosan or putrescine application at 0, 50, 100, 150 ppm and three levels of irrigation (7, 14 and 21 days) contributing to three levels of drought stress (zero, moderate and severe, respectively) on growth, leaf biochemical attributes and antioxidant enzymes activity. Results showed that most of the vegetative growth indices, plant height %, stem diameter %, leaves number, area, fresh and dry weight and relative water content(RWC) %,leaf carbohydrates and protein % were significantly decreased with increasing drought level and that chitosan and putrescine application resulted in enhancement gradually of the previous parameters by increasing concentrations applied. Putrescine was more effective at 50 and 100ppm compared to 150 ppm, whereas chitosan was more effective at 100 and 150ppm than 50 ppm .

“…Though there recorded no such variation in band numbers but plants could vividly tune the genetic makeup to antagonize the Cd sensitivity with CAT expression. The downregulation of CAT activity as reported in many crop species under metal stress could be explained either impairment of de novo synthesis of the enzyme or the overload of cellular H 2 O 2 , if any, that creates toxicity to denature the proteins [23]. In conext to bioindication the apparent no change of CAT expression to Cd toxicity could thus find hardly any possibility in Marsilea plants.…”

In a hydroponic based experiment, the Cd toxicity is monitored with some cellular responses of Marsilea plant. Initially, plants were grown under varying concentrations (0, 50, 100 and 200 µM of Cd) of cadmium (Cd) with supplementation of 2 mM spermidine (Spd). The oxidative stress developed by Cd overaccumulation was measured with fall in Relative Growth Rate (RGR) by 27.11% to 59.83% growth reduction over control under varying Cd treatments. The retrieval of RGR was recovered by 1.59 folds as compared to the highest concentration of Cd (200 µM) when plants were fed with Spd. A concomitant degradation of chlorophyll was recorded in dose-dependant manner, however, the retrieval was not much pronounced with Spd. On the contrary, the nonoxidant thiol had borne more clarity with ongoing Cd concentration and appeared to be 40.51% increase maximally for GSH: GSSG at the highest concentration of Cd. Spd has minimized the ratio by 27.4%. The recovery of osmotic turgidity was indexed with a sharp rise in glycine betaine by 3.86 folds maximum at the highest concentration of Cd over control which declined by 30.9% with Spd. Another cellular response of treated plants was more evident from their isozymic profiles with regard to superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPX). The intensity of protein expression was significantly variable but not in band numbers as evident from Cd treated plants. In vitro enzyme assay of catalase showed as declining trend within the limit of 33.13% to 43.22% which was reported by 1.45 folds when Spd was applied. Therefore, from the present study, the cellular responses of Marsilea plant which showed compatibility for their expression with Cd toxicity could be hypothesized as a case of bioindication.

ABSTRACT. The use of allelochemicals as weed control agents is becoming widely investigated. However, the impact of these bioherbicides on cultivated plants is less known. This study was carried out in order to evaluate the allelopathic effects of the aqueous extract of Clinopodium menthifolium on black nightshade (Solanum nigrum) antioxidant properties to explore the potential of this species in weed control and on pepper (Capsicum annuum) antioxidant properties so as to assess its possible side effects when applied as bioherbicide in organic production. Taking into account that plant extracts should be an alternative source for insect control, additional aim was also to evaluate contact effect of C. menthifolium aqueous extract against the greenhouse whitefly (Trialeurodes vaporariorum). Analysis by HPLC confirmed the presence of gallic acid, caffeic acid and 2-hidroxy-cinnamic acid as major components in the C. menthifolium aqueous extract. Both tested concentrations of C. menthifolium aqueous extract induced lipid peroxidation in black nightshade leaves and roots. It was observed that the aqueous extract with a concentration of 0.1% showed a toxic effect with 50% mortality of greenhouse whitefly adults.
