Global Perspectives On First Generation Liquid Biofuel Production, Rok Fink, Saso Medved
Turkish Journal of Agriculture and Forestry
Transport today is mostly sustained by liquid fossil fuels, despite the fact that the invention of the combustion engine started with biofuels. However, known environmental impacts and the instability of the fossil-fuel market have revived the status of biofuels. Some concerns have appeared regarding how emerging global climate changes will affect biofuels' feedstock production, since agriculture is strongly dependent on climate variables. Therefore, numerical models were introduced to calculate how temperature and precipitation could affect crop production for biodiesel and bioethanol production. Furthermore, 4 scenarios projected by the Intergovernmental Panel on Climate Change were put into the calculations. The results …

Na^+/H^+ antiporters have been suggested to play important roles in salt tolerance in plants. English cordgrass (Spartina anglica) is a gramineous halophyte with very strong salt tolerance. It possesses salt glands in its stems and leaves, through which excess salt can be excreted. In this study, a vacuolar Na^+/H^+ antiporter homologous gene (temporarily named SaNHX1) was isolated from Spartina anglica by RT-PCR and rapid amplification of cDNA ends (RACE). Southern blot analysis suggested that there might be 2 or 3 copies of the vacuolar Na^+/H^+ antiporter genes in the English cordgrass genome. Northern blot analysis showed that the expression of …
