    Leading experts in organic solar cells say the field is being damaged by questionable reports about ever bigger efficiency claims, leading the community into an endless and dangerous tendency to outbid the last report. In reality these solar cells still show low efficiencies that will need to improve significantly before they become a success. To counter the hype, scientists call on the community to press for independent verification of claimed efficiencies. Biopact sees a similar trend in the field of biofuels from algae, in which press releases containing unrealistic yield projections and 'breakthroughs' are released almost monthly. Eurekalert - October 16, 2007.

    According to Tarja Halonen, the Finnish president, one third of the value of all of Finland's exports consists of environmentally friendly technologies. Finland has invested in climate and energy technologies, particularly in combined heat and power production from biomass, bioenergy and wind power, the president said at the UN secretary-general's high-level event on climate change. Newroom Finland - September 25, 2007.

    Spanish engineering and energy company Abengoa says it had suspended bioethanol production at the biggest of its three Spanish plants because it was unprofitable. It cited high grain prices and uncertainty about the national market for ethanol. Earlier this year, the plant, located in Salamanca, ceased production for similar reasons. To Biopact this is yet another indication that biofuel production in the EU/US does not make sense and must be relocated to the Global South, where the biofuel can be produced competitively and sustainably, without relying on food crops.

IHB Network - September 21, 2007.

    Analysts fear that record oil prices will fuel general inflation in Kenya, particularly hitting the poorest hard. They call for the development of new policies and strategies to cope with sustained high oil prices. Such policies include alternative fuels like biofuels, conservation measures, and more investments in oil and gas exploration. The poor in Kenya are hit hardest by the sharp increase, because they spend most of their budget on fuel and transport. Furthermore, in oil intensive economies like Kenya, high oil prices push up prices for food and most other basic goods. All Africa - September 20, 2007.

    Finland's Metso Power has won an order to supply Kalmar Energi Värme AB with a biomass-fired power boiler for the company’s new combined heat and power plant in Kalmar on the east coast of Sweden. Start-up for the plant is scheduled for the end of 2009. The value of the order is approximately EUR 55 million. The power boiler (90 MWth) will utilize bubbling fluidized bed technology and will burn biomass replacing old district heating boilers and reducing the consumption of oil. The delivery will also include a flue gas condensing system to increase plant's district heat production. Metso Corporation - September 19, 2007.

Bacteria use plant defence for genetic modification - new perspective in GMO debate

Genetically modified organisms (GMOs) are set to play an important role in future food and fuel production (previous post). The father of the technique of genetically modifying crops, Marc Van Montagu, for example, is a staunch supporter of such plants, because they can improve yields, end hunger in developing countries and unlock a vast potential for the production of sustainable biofuels and bioproducts that allow us to fight climate change (more here). But transgenic crops and GMOs used for bioconversion remain highly controversial, especially in Europe. Scientists from the continent now describe an entirely natural process occuring in plant cells that is similar to how genomes are artificially modified in engineered crops. Their findings, published today in Science, may offer a new perspective in the debate over GMOs.

Bacteria that cause tumours in plants modify plant genomes by skilfully exploiting the plants' first line of defence. Utilising the plant's own proteins, bacterial genes infiltrate first the nucleus then the plant genome, where they reprogramme the plant's metabolism to suit their own needs. This process was recently discovered as part of an Austrian Science Fund FWF project.

The genetic manipulation of plants is both a subject of great controversy in Europe and a tactic already practiced by certain bacteria. The soil bacterium known as crown-gall bacterium (Agrobacterium) manipulates the genetic make-up of plants by inserting its own DNA into the nuclei and, consequently, into the genetic material of the plant cells. The genetically modified plants are then reprogrammed to ensure uninhibited cell division and produce nutrients to feed the bacteria. What was not previously understood is exactly how bacteria genes infiltrate the cell's nucleus - particularly as the defence mechanisms of plant cells react so rapidly to bacterial invasion.

A surprising detail of this process has now been uncovered by the team of Prof. Heribert Hirt working at the Max F. Perutz Laboratories at the University of Vienna and the URGV Plant Genomics Institute near Paris which Hirt joined as future director earlier this year. VIP1, a plant cell protein, is at the heart of their research. It was already known that this protein supports the transport of bacterial DNA known as T-DNA into the nucleus, and yet the exact role of VIP1 was unclear.

Prof. Hirt explains: "We were able to show that VIP1 is a protein that regulates various genes designed to defend against bacterial invasion. However, VIP1 only occurs initially in the cytoplasm of cells and - in order to fulfil its role as a regulator - it then needs to migrate into the nucleus. It is precisely this movement that the bacterium exploits in order to inject its T-DNA into the nucleus." Hirt compares this strategy, which inevitably means that the plants own defences cause its downfall, to the famous Trojan Horse:
:: :: :: :: :: :: :: ::

The scientist explains further that plants have an immune defence mechanism that is triggered when the plant detects certain molecules of the invader and works by activating genes in the nucleus. Once the invader has been detected, specific protein kinases in the cytoplasm are activated. These are enzymes that regulate the activity of other proteins by adding phosphate groups to them. One of the proteins phosphorylated by these protein kinases is VIP1, which is only granted access to the nucleus after this phosphorylation, so that it can activate the relevant defence genes there.

The following model illustrates the early processes in an infected plant cell. The invasion of T-DNA and the identification of the bacterium as an invader occur simultaneously. While protein kinases phosphorylate VIP1 in the cytoplasm, the bacterial T-DNA adheres to VIP1, thereby enabling it to infiltrate the nucleus unnoticed. The result is the joint infiltration of both friend and foe. Once inside the nucleus, the T-DNA is inserted into the plant genome and the process of tumour formation begins while the activated defence genes simultaneously organise the plant cell's defence mechanisms. It is too late though - the cell has already been transformed.

The fact that genetic modifications occur continuously in nature in this way offers a new angle to look at the controversies over transgenic crops.
