Fusarium graminearum causes head blight disease in wheat, and to help understand the infection process we studied global gene expression of F. graminearum in a time series of 24 to 196 hours after inoculation, compared to a water control. The infection is rapid and already after 48h over 4000 genes is expressed. The number of genes expressed increased over time up to 96h (>8000 genes), and went down again 144h and 192h post inoculation. After subtraction of genes found expressed on complete media, during C and N starvation, and on barley, only 355 were found exclusively expressed in wheat, mostly ones with unknown function (72,6%). These were mainly found in SNP enriched islands on the chromosomes, suggesting a higher evolutionary selection pressure of wheat specific genes. The annotated genes found were enriched in functional groups involved in allantoin and allantoate transport, detoxification, nitrogen, sulfur and selenium metabolism, secondary metabolism, carbohydrate metabolism and degradation of polysaccharides and ester compounds. Several putative secreted virulence factors were also found expressed in wheat.

Oil transportation from the Russian part of the Barents Region along the Norwegian coast had insignificant volumes before 2002. However, in 2002 there was a dramatic increase in oil shipment, when 4 million tons was delivered westwards by the Barents Sea. In 2003, the volume reached 8 million tons. The trend continued in 2004, and about 12 million tons of export oil and refined products were transported from the Russian part of the Barents Region to the western market along the Norwegian coast. From 2005 to 2008, the annual shipment volumes were on the levels between 9.5 and 11.5 million tons. In 2009, Russian oil-and-gas export cargoes carried by the Barents Sea rose to 13 million tons, and in 2010, exceeded the level of 15 million tons. Norwegian Snøhvit, the first offshore production in the Barents Sea, added to these volumes 5 million cubic metres of liquefied gases (LNG and LPG) each of two recent years. The terminals loading oil for export in the Russian Western Arctic seas have been continuously developed, and the overall shipping capacity has been enlarged. The changes in oil volumes carried for export through the Barents Sea during the recent years were not so much dependent on the terminals‟ capacities and logistic schemes as on the external factors. The changes in the export taxes by the State and rates for cargo transportation by Russian railways, development of new trunk pipelines and sea terminals in the Baltic Sea and Far East by Transneft, bankruptcy of Volgotanker were a few examples that induced oil transport operators to develop new terminals in the Kola Bay and to focus more on petroleum products than crude oil. The big oil export challenges that occurred in the recent years due to conflicts between Russia and neighbouring transit countries made the Russian Government and Transneft to reorient the Russian oil export routes and increase the capacities of the Baltic Pipeline System (BPS) to 75 million tons in 2007, with the prospects to reach 150 million tons in 2015. Construction of Eastern Siberia-Pacific Ocean pipeline (ESPO) was launched, the first phase with a branch to China was put on stream in 2010, and a new terminal in the Far East started to ship oil for export. In the south, the project of Burgas-Alexandropoulis pipeline was developed. In the north, Kharyaga-Indiga pipeline project was frozen because a new Varandey terminal came on full scale. The year of 2009 started with an export gas transit conflict between Russia and Ukraine. The Government of Russia and Gazprom highlighted the importance of constructing Nord Stream and South Stream gas pipelines through the Baltic and the Black seas to let Russia export natural gas to Western Europe bypassing its neighbouring countries, the former Soviet sister-republics. In 2009, Russia launched its first LNG plant in Far East in Sakhalin. Three more LNGs are planned in the Arctic, in the Kola Peninsula, in Nenets region, and in Yamal. Those plants can start shipping liquefied gas in 2016-2017. The first oil from offshore production in the Russian Barents should come from Prirazlomnoye oil field. Prirazlomnaya platform left Severodvinsk and came to Murmansk for completion in the fall of 2010. The plan is to deliver the platform on its production destination and put the oil field on stream in 2011. The Prirazlomnaya platform will be the second big offshore installation in the Pechora Sea. The first one, 12 million tons Varandey terminal, was launched in 2008, and already in 2009 sent more than 7 million tons of crude oil for export. Lukoil plans to increase the terminal oil offloading volumes building 8 million tons pipeline from Kharyaga to Varandey. In the present report on oil transportation in the Barents Region, we have given special attention to the description of the existing and prospective offshore and onshore oil and gas terminals in the northern regions of Russia and Norway, and their connection to hydrocarbon reserves on one hand and to the export routes on the other. We demonstrate that even without a Russian oil trunk pipeline to the Barents Sea coast, that was discussed a few years ago, the overall capacity of the terminals shipping oil and gas for export along the northern coast of Russian and Norway can reach 100 million tons in five years perspective. In Russia, about 50 million tons of crude oil and petroleum products can be delivered by railway to the Murmansk port terminals in the Barents Sea, and Kandalaksha and Arkhangelsk in the White Sea. In addition, up to 20 million tons of oil will come from the northern Timano-Pechora oil fields - 12.5 million via the new Varandey terminal, and 7.5 million from Prirazlomnoye field. Dolginskoye oil field, which is estimated to be three times as big as Prirazlomnoye, will be the next large offshore field in the Pechora Sea put on stream. With port infrastructure developed on Yamal, the terminals in the Kara Sea can ship 3 million tons of Western Siberia crude oil for export. Shtokman in the Barents Sea and Tambey in Yamal gas fields can offload 12.5 million tons of liquefied gas in 2017, when the first phases of both LNG plants are completed. In Norway, in addition to 5 million tons of liquefied gas shipped from Snøhvit, Goliat oil field in the Barents Sea should be put on stream in 2013 and produce 5 million tons of oil in 2014. In 2010, there were made a number of historic voyages by the Northern Sea Route. We will see more cargo vessel passages through this Arctic shipping lane in 2011. In a long term perspective, the Northern Sea Route will give the way for huge Yamal and Kara Sea oil-and-gas resources to the western markets via the Barents Sea; and it will also open possibilities for transit cargo transportation from Europe to Asia Pacific along the Arctic coast. In the European part of Russia there are three possibilities for shipping oil for export - through the Black Sea, the Baltic Sea, and the Barents Sea. Out of these three options, only the northern way can provide the stable cargo shipping directly to major European and North American harbours, avoiding transit challenges through neighbouring countries or heavy traffic in the sea straits. Oil pollution prevention should be the central issue during oil transportation in the Barents Sea. The year 2010 was marked with the Mexican Gulf accident, the largest oil spill ever happened in the sea that put issues of marine environmental protection against oil pollution to a high international political agenda. In this report, we pay attention to the environmental safety matters in oil transportation and Norwegian-Russian co-operation in the oil pollution prevention. We see more advanced and safer terminals and vessels operating in the region. However, the number of accidents with sea vessels was increasing worldwide the last 10 years due to human errors. Traffic control and monitoring are developed both in Norway and Russia. Establishment of an early warning and notification system between two countries should be the next step. The Treaty on a delimitation line in the Barents Sea, that was signed between Norway and Russia in 2010 and ratified in 2011, should put relations between two countries on a new level opening wider possibilities for oil-and-gas, maritime shipping and environmental cooperation.

In 2004, WWF, the international conservation organization opened an office in Murmansk, and the Barents Ecoregion Program was officially re-launched. The funding for the program comes from mainly two sources, WWF UK and WWF-Norway, granted from the Norwegian Ministry of Environment and the Ministry of Foreign Affairs. This report aims to evaluate the effectiveness of the Barents program The methodology is mainly based on interviews with cooperating institutions in Murmansk and staff from WWF in Murmansk and Oslo. The WWF conservation strategy for the Barents Sea has been reviewed, together with the yearly reports from the program. Comments from donors are to some extent included. The main conclusion from the interviews and review confirms the author"s impression that WWF has a strong position and contribute considerably to the overall conservation in the Barents region.WWF has regular meetings with the governor environmental administration, deliver documentation to different conservation processes and appear in the media as a critical voice when necessary and a supporter when good decisions are made.

Ved dyrking av jordbær og bringebær i plasttunnelar unngår ein direkte nedbør på planter og bær og kan på den måten lettare takle soppsjukdommar i økologisk dyrking. Tunneldyrking gir samtidig stabile leveransar og kan gi større avling og betre kvalitetet. På den andre sida er plasttunnelar meir kostnads- og arbeidskrevjande. Dyrking av bær i plasttunnel er blitt ein utbredt dyrkingsmåte i enkelte land. I Norge har vi ein liten produksjon av bær i tunnel.
