“…Genetically increased capacity for metal-induced Cys synthesis was shown to support survival of Arabidopsis under acute Cd stress (Dominguez-Solis et al, 2004). In this connection, the capability of plant to accumulate stress-induced polyamine is of great interest; polyamines manifest a multifunction defensive role against various abiotic factors, heavy metal in particular (Kuznetsov et al, 2006). Therefore, their properties, such as an easy chelation of heavy metal, Ni in particular (Koutensky et al, 1995), attract the attention of researchers.…”

Nickel is essential for many plant species to complete their life cycle but higher concentrations of this metal are toxic and may severely interfere with many physiological and biochemical processes of plants. In recent researches, either sodium nitroprusside (as nitric oxide donor) or exogenous polyamines were used to counteract the effect of heavy metal stress. In this research hyoscyamus plants were pre-treated with 10 and 20 µM Arg (as a precursor of NO or polyamines) and then plants were treated with 50 and 100 µM Ni. Elevated hydrogen peroxide content and lipoxygenase (LOX) activity showed that Ni induced oxidative damages. Antioxidant enzyme activity also increased in those plants which were under Ni stress. In plants, which were pretreated with Arg, the concentration of Ni increased in shoot, while the H 2 O 2 content and the activity of LOX, catalase (CAT), guiacol peroxidase (GPX) and ascorbate peroxidase (APX) enzymes decreased. It is shown for the first time that pre-treatment of hyoscyamus plant with Arg increased plant capability to accumulate Ni in its aboveground organs by 1.5-2 times and reduced its toxic effects indicated by measurement of oxidative parameters. It might be true because Arginine induced alleviation of Ni toxicity and accelerated transport by chelating of Ni in plants directly or through production of polyamines.

“…A reduction in the amount of spermidine synthase may relate to changes in the oxidative stress response as both spermidine and its precursor spermine are anti-oxidants which are also transcription factors for other genes involved in the degradation of reactive oxygen species (Kuznetsov et al 2006;Tkachenko & Fedotova 2007;Chattopadhyay et al 2009). …”

Proteomic response of Trichoderma aggressivum f. europaeum to Agaricus bisporus tissue and mushroom compost

a b s t r a c tA cellular proteomic analysis was performed on Trichoderma aggressivum f. europaeum.Thirty-four individual protein spots were excised from 2-D electropherograms and analysed by ESI-Trap Liquid Chromatography Mass Spectrometry (LC/MS). Searches of the NCBInr and SwissProt protein databases identified functions for 31 of these proteins based on sequence homology. A differential expression study was performed on the intracellular fraction of T. aggressivum f. europaeum grown in media containing Agaricus bisporus tissue and Phase 3 mushroom compost compared to a control medium. Differential expression was observed for seven proteins, three of which were upregulated in both treatments, two were down regulated in both treatments and two showed qualitatively different regulation under the two treatments. No proteins directly relating to fungal cell wall degradation or other mycoparasitic activity were observed. Functions of differentially produced intracellular proteins included oxidative stress tolerance, cytoskeletal structure, and cell longevity. Differential production of these proteins may contribute to the growth of T. aggressivum in mushroom compost and its virulence toward A. bisporus.

“…Proline also serves a conspicuous role in the alleviation of water and salt stress in plants (Larcher, 2003;di Toppi and Pawlik-Skowronska, 2003). Many species of plants, faced with drought or an excess of salt in the external environment, induce the synthesis of proline in the root system, and this serves as a protectant against negative hydric changes in the external environment (Kuznetsov and Shevyakova, 1999;de Ronde et al, 2000;Ramanjulu and Sudhakar, 2000).…”

Abstract-Most snakes and lizards produce eggs with flexible shells that interact with the environment to maintain water balance. Geckos produce rigid eggshells that are independent of an external source of water and can be oviposited in more open, dryer locations. In this study, we analyzed and compared the amino acid composition of 24 lizard species, six snake species, and four outgroups (including avian and reptilian elastin and chicken eggshell). Rigid Gecko eggshells had significantly lower levels of seven of the 17 amino acids evaluated. Multivariate analysis showed that proline was the most important amino acid in distinguishing between these two groups of eggshells, occurring at significantly higher levels in flexible eggshells. High levels of proline have also been observed in the eggshells of other species. Proline and other amino acids are associated with the alleviation of water and salt stress in plants.
