“…Santa-Cruz et al (1997b) showed that free polyamine accumulated in Lycopersicon pennellii during the first 15 min of salt treatment and decreased thereafter. Similarly, Das et al (1995), Santa-Cruz et al (1997a), Tonon et al (2004), and Legocka and Kluk (2005) reported that a short period of stress increased the polyamine levels, whereas, under longer stress duration, only a small change in the polyamine levels was observed, showing that polyamine accumulation takes place primarily at the onset of stress. In this regard, polyamines were suggested as short-term salt-tolerance traits in tomato (Santa-Cruz et al 1998) and, thus, can be considered as a biochemical indicator (Sanchez et al 2005).…”

“…This compound was also found in up to 50-fold higher concentrations in Clipper leaf tips, but only 5-fold in Sahara leaf tips treated with 1,000 mM B compared to the respective treated leaf base (Supplemental Table S7) or 6-fold higher concentrations compared to the control Clipper tip (Supplemental Table S8). Putrescine belongs to the class of aliphatic polyamines shown to be involved in both abiotic and biotic stress responses (Walters, 2003;Capell et al, 2004;Legocka and Kluk, 2005). In tobacco (Nicotiana tabacum), putrescine levels were elevated following B deficiency (Camacho-Cristobal et al, 2005) and the authors proposed a potential link between B and putrescine.…”

An Investigation of Boron Toxicity in Barley Using Metabolomics

Boron (B) is an essential micronutrient that affects plant growth at either deficient or toxic concentrations in soil. The aim of this work was to investigate the adaptation of barley (Hordeum vulgare) plants to toxic B levels and to increase our understanding of B toxicity tolerance mechanisms. We used a metabolomics approach to compare metabolite profiles in root and leaf tissues of an intolerant, commercial cultivar (cv Clipper) and a B-tolerant Algerian landrace (cv Sahara). After exposure to elevated B (200 and 1,000 mM), the number and amplitude of metabolite changes in roots was greater in Clipper than in Sahara. In contrast, leaf metabolites of both cultivars only responded following 1,000 mM treatment, at which B toxicity symptoms (necrosis) were visible. In addition, metabolite levels were dramatically altered in the tips of leaves of the sensitive cultivar Clipper after growth in 1,000 mM B compared to those of Sahara. This correlates with a gradual accumulation of B from leaf base to tip in B-intolerant cultivars. Overall, there were always greater differences between tissue types (roots and leaves) than between the two cultivars. This work has provided insights into metabolic differences of two genetically distinct barley cultivars and information about how they respond metabolically to increasing B levels.Boron (B) is an essential micronutrient for vascular plants. However, when B is present at high concentrations in the soil or ground water, plant growth and reproduction can be affected by B toxicity. B toxicity has been recognized as an important problem limiting crop production in the low rainfall and on highly alkaline and saline soils in regions of Australia, West Asia, and North Africa. Because soil amelioration is impractical, the development of B-tolerant cultivars is a rational solution to the problem.B freely diffuses into the roots as boric acid [B(OH) 3 ; pK a 5 9.25] and accumulates in the cytoplasm as the borate anion [B(OH) 4 2 ] due to pH-dependent interconversion. An inability to exclude B from the roots results in high B concentrations in the tissue. B phytotoxicity manifests itself in a broad range of physiological effects, including decreased shoot and root growth, root cell division and RNA content, reduced leaf chlorophyll, lower photosynthetic rates and stomatal conductance, and reduced levels of lignin and suberin (for review, see Nable et al., 1997). Leaf symptoms of toxicity in barley (Hordeum vulgare) are characterized by interveinal chlorotic and/or necrotic patches, generally at the margins and tips of older leaves. This reflects the accumulation of B at the end of the transpiration stream (Nable et al., 1997). Following long-term exposure to high B concentrations in the soil, overall vegetative plant growth is retarded and this leads to either a reduction in or a complete lack of seed set.B is also an essential nutrient, although its role in plant growth, development, and metabolism remains to be clarified. Originally, B was thought to be essentially immobile in the ...

“…One of the most commonly occurring abiotic stressors is osmotic stress (Yokoi et al 2002;Rao et al 2006). Osmotic stress may be a result of diverse abiotic factors such as drought, salinity, cold, polyethylene glycol, mannitol or sorbitol (Verslues et al 1998;Munnik and Meijer 2001;Legocka and Kluk 2005). Osmotic stress causes many adverse symptoms, which include, among others: plant wilting, impaired growth and development, lower yield or even its absence.…”

Osmotic stress causes many adverse symptoms in plants, which include, for example, growth limitation and decrease or even absence of yield. Proteomic analyses of plant responses to stressors could lead to the introduction of crops with high resistance to osmotic stress. Such plants would be characterized by high yield even under unfavorable environmental conditions. In this article we describe changes in the protein profiles occurring in response to mild and moderate osmotic stress in triticale roots. Analysis of the protein profiles of these roots showed an increased abundance of 14 and a decreased abundance of 11 proteins under mild osmotic stress conditions while a moderate osmotic stress caused an increased abundance of 18 and a decreased abundance of 33 proteins. Twenty-five proteins, whose quantity altered under stress were identified using MALDI-TOF mass spectrometry. The identified proteins were classified into the categories of proteins associated with: defense mechanisms, metabolism, transcription, cell structure, protein synthesis, transport and signal transduction. The functions of identified proteins were discussed in relation to osmotic stress. Some of the identified proteins may be responsible for the adaptation of plants to adverse conditions.
