Root physiological and transcriptional response to single and combined S and Fe deficiency in durum wheat
No full textA number of connections and insights are emerging regarding the molecular and physiological basis of Fe and S interplay response of combined Fe and S starvation of durum wheat roots are here presented. Microarray analysis revealed that 128 transcripts were commonly modulated by both single and combined deficiencies, thus representing the “core” set of transcripts involved in the responses both to S and Fe shortage, whereas a total of 509 transcripts were modulated only by the simultaneous deficiency of S and Fe. Interestingly, among these latter, most of the genes of nitrate uptake and assimilation were down-regulated, while those involved into ammonium uptake were up-regulated as confirmed by the decrease in nitrate reductase enzyme activity. Transcripts playing a role into phosphate uptake were down-regulated in agreement with the observed lower P accumulation in roots. Combined deficiency mainly up-regulated transcripts involved with oxidative stress response although the related enzyme activities did not appear to differ significantly. Results allowed the identification of transcripts that are specific as well as those that are shared among single and combined deficiency responses, thus providing a starting point for detailed studies on candidate genes to improve the understanding of the molecular basis of nutrient acquisition
Combined Heat and Power Plant and District Heating and Cooling Network: A Test-Case in Italy with Integration of Renewable Energy
No full textThe 2012 European energy efficiency directive supported the development of cogeneration combined heat and power (CHP) and district heating and cooling (DHC) networks, stressing the benefits of a more efficient energy supply, the exploitation of recovered heat, and renewable resources, in terms of fuel consumption and avoided costs/emissions. Policy decisions play a crucial role: technical and environmental feasibility of CHP is clear and well demonstrated, whereas economic issues (fuel prices, incentives, etc.) may influence its actual application. In this framework, the introduction of low-carbon technologies and the exploitation of renewable energies are profitable interventions to be applied on existing plants. This work focuses on a small CHP plant, installed in the 90 s and located within a research facility in Italy, designed to supply electricity and heat/cool through a district network. On the basis of monitored consumption of electricity, heating, and cooling, energy fluxes have been analyzed and an assessment was performed to get a management profile enhancing both operational and economic parameters. The integration of renewable energies, i.e., solar-powered systems for supporting the existing devices, has been evaluated, thus resulting in a hybrid trigeneration plant. Results demonstrate how the useful synergy between CHP and DHC can not only be profitable from the economic point of view, but it can also create conditions to considerably boost the integral deployment of primary energy sources, improving fuel diversity and then facing the challenge of climate change toward sustainable energy networks in the future
Multiple linear regression and linear mixed models identify novel traits of salinity tolerance in Olea europaea L
No full text: Olive can be considered as moderately tolerant to salinity, with marked differences among cultivars. In the present study, two olive cultivars with different salt tolerance, 'Leccino' (sensitive) and 'Frantoio' (tolerant), were treated with 120 mM of NaCl for 30 days. We measured the expression of genes involved in the management of sodium in the leaves, such as NHX, SOS1 and H+ ATPase, and the concentration of Na+, K+, Mn2+, Mg2+ and Ca2+ in the roots, bark, xylem and leaves of the olive plants. The results were analyzed with multiple linear models and mixed models. Furthermore, we utilized the analysis of covariance to find significant relationships in our data. Both cultivars significantly reduced net photosynthesis and increased water-use efficiency after 30 days of treatment. Sodium accumulated significantly in the roots of both cultivars, and 'Leccino' plants were also able to translocate it to the leaves and the bark. The NHX and vacuolar ATPase subunit E genes were significantly overexpressed in both the cultivars treated with NaCl. The SOS1, ATPase11 and ATPase8 genes were overexpressed in 'Frantoio'. The covariance between gene expression and element concentrations data was analyzed to identify significant interactions between cultivars and treatments. Na+ accumulation in the roots of 'Frantoio' was positively related to the accumulation of K+, Mn2+, Mg2+ and Ca2+ in the xylem, bark and leaves. 'Frantoio' capability to mobilize elements, especially Ca2+, together with the overexpression of key genes for sodium management, could be crucial for salt tolerance

A Human Rights Approach to Environmental Health
No full textThis chapter explores the interface between health and the environment through the human rights prism, focusing on the environmental dimension of the right to health and on the now widely recognized right to a healthy, safe and clean environment. To this end, the chapter intends to offers a comprehensive analysis of the relevant provisions contained in human rights treaties and the obligations stemming therefrom. The review of these legal sources is completed by a critical assessment of the case law produced by regional human rights bodies and their evolutive interpretation of individual rights and corresponding State obligations in this field, with a special focus on the case law of the European Court of Human Rights. The aim of this legal analysis is to evaluate the added value of a human rights approach to environmental health litigation, with a view to best achieving the overarching goal of public health protection from environmental harm. The author highlights that human rights can be used in court as effective tools to protect public health against the adverse effects of environmental degradation and severe pollution. She also stresses that the potential of human rights bodies in the field of environmental health is yet fully unexpressed, but further positive developments towards the protection of collective and intergenerational rights related to the environment and human health can be achieved thanks to the dynamic and evolutive approach adopted by these bodies and through the virtuous circle created by judicial cross-fertilization
Interaction Between Sulfur and Iron in Plants
No full textIt is well known that S interacts with some macronutrients, such as N, P, and K, as well as with some micronutrients, such as Fe, Mo, Cu, Zn, and B. From our current understanding, such interactions could be related to the fact that: (i) S shares similar chemical properties with other elements (e.g., Mo and Se) determining competition for the acquisition/transport process (SULTR transporter family proteins); (ii) S-requiring metabolic processes need the presence of other nutrients or regulate plant responses to other nutritional deficiencies (S-containing metabolites are the precursor for the synthesis of ethylene and phytosiderophores); (iii) S directly interacts with other elements (e.g., Fe) by forming complexes and chemical bonds, such as Fe-S clusters; and (iv) S is a constituent of organic molecules, which play crucial roles in plants (glutathione, transporters, etc.). This review summarizes the current state of knowledge of the interplay between Fe and S in plants. It has been demonstrated that plant capability to take up and accumulate Fe strongly depends on S availability in the growth medium in both monocots and dicot plants. Moreover, providing S above the average nutritional need enhances the Fe content in wheat grains, this beneficial effect being particularly pronounced under severe Fe limitation. On the other hand, Fe shortage induces a significant increase in the demand for S, resulting in enhanced S uptake and assimilation rate, similar to what happens under S deficiency. The critical evaluation of the recent studies on the modulation of Fe/S interaction by integrating old and new insights gained on this topic will help to identify the main knowledge gaps. Indeed, it remains a challenge to determine how the interplay between S and Fe is regulated and how plants are able to sense environmental nutrient fluctuations and then to adapt their uptake, translocation, assimilation, and signaling. A better knowledge of the mechanisms of Fe/S interaction might considerably help in improving crop performance within a context of limited nutrient resources and a more sustainable agriculture
