élevés, plus de quatre millions de producteurs et de consommateurs verraient une baisse sensible de leurs niveaux de pauvreté d'ici 2016 ", a déclaré Roberto La Rovere, socio-économiste au CIMMYT et principal auteur de l'étude. Menée dans le cadre du projet maïs tolérant à la sécheresse pour l'Afrique (Drought Tolerant Maize for Africa Initiative - DTMA), l'étude a été financée par la Fondation Bill & Melinda Gates et la Fondation Howard G. Buffett, toutes deux aux Etats-Unis. Selon le communiqué de presse, les conditions climatiques pour la culture de maïs devraient empirer, du moins dans certaines parties de l'Afrique, au cours des prochaines décennies - augmentant ainsi le besoin de maïs tolérant à la sécheresse. Une étude réalisée par l'Institut international de recherche sur l'élevage (International Livestock Research Institute - ILRI), par exemple, a constaté que le simple fait de ne pas passer au maïs tolérant à la sécheresse pourrait réduire les rendements à travers la région de près d'une tonne à l'hectare.

Journal: International Association of Agricultural Economists>2009 Conference, August 16-22, 2009, Beijing, China Label: Detection Dispersion Socioeconomic Keywords: Co-existence Traceability Food production Abstract: In contrast to the increasing use of GM plants in world-wide agriculture, the acceptance of GM food is still low in the European Union (EU). In order to ensure freedom of choice for consumers and users of GM and non-GM products, GM food and feed products have to be labeled in case a tolerance threshold of 0.9 % is exceeded for EU authorized GMOs. This paper aims to quantify the cost of traceability and co-existence systems for GM food from the seed to the food level for sugar, wheat starch and rapeseed oil for human consumption in Germany respecting the 0.9 % threshold for labelling of GM food. The cost calculation for traceability and co-existence measures follows the principle of aggregating all incurred cost on the different levels of the value chain and to increase the price of the final product at each level. Altogether the measures to ensure co-existence and traceability lead to 5 % to 13 % higher price for GMO-free rapeseed oil, to 2 % to 5 % higher prices of GM-free sugar and to 8 % price increase for GMO-free wheat starch.

Journal: The Plant Journal 63, 6, 1054-1062.

Label: Physiol Keywords: AtALMT12 malate R-type guard cell anion channel Arabidopsis Abstract: Stomatal pores formed by a pair of guard cells in the leaf epidermis control gas exchange and transpirational water loss. Stomatal closure is mediated by the release of potassium and anions from guard cells.

Anion efflux from guard cells involves slow (S-type) and rapid (R-type) anion channels. Recently the SLAC1 gene has been shown to encode the slow, voltage-independent anion channel component in guard cells. In contrast, the R-type channel still awaits identification. Here, we show that AtALMT12, a member of the
