| The expression of 28 high light (HL)-responsive genes of Arabidopsis was analysed in response to environmental and physiological factors known to influence the expression of the HL-responsive gene, ASCORBATE PEROXIDASE2 (APX2). Most (81%) of the HL-responsive genes, including APX2, required photosynthetic electron transport for their expression, and were responsive to abscisic acid (ABA; 68%), strengthening the impression that these two signals are crucial in the expression of HL-responsive genes. Further, from the use of mutants altered in reactive oxygen species (ROS) metabolism, it was shown that 61% of these genes, including APX2, may be responsive to chloroplast-sourced ROS. In contrast, apoplastic/plasma membrane-sourced H2O2, in part directed by the... |

| The network named REMONOR (REseau MOllusqueNORmandie) aims to assess mortality, growth and tissue quality of the Pacific oyster, Crassostrea gigas, cultivated in Normandy over an annual cycle. This local network relies on the same material and methods as the national one named REMORA (REseau Mollusques Ressources Aquacoles). The study was carried out in 17 sites, which were distributed in the four basins where oyster rearing occurs in Normandy (West and East coast of Cotentin, Baie des Veys and Meuvaines). In 2003, a new site was added, which was located in the area of Ver-Sur-Mer (Calvados). The results obtained in 2003 showed a low annual mortality for adults (8%) as well as for juveniles (10%). Growth was also low for the two age classes of oyster... |
