The sixth International Symposium on Genetics and Molecular Biology of Plant Nutriti9n was held in Elsinore, Denmark from August 17-21, 1998 and organised by th RiS0 National Laboratory in the year of its 40 anniversary. The 98 participants represented 23 countries and 80 scientific contributions with 43 oral and 37 poster presentations. The symposium addressed the molecular mechanisms, physiology and genetic regulation of plant nutrition. The Symposium brought together scientists from a range of different disciplines to exchange information and ideas on the molecular biology of mineral nutrition of plants. The symposium emphasised: • Bridging the gab between molecular biology, applied genetics, plant nutrition and plant breeding. • The development of methodologies to improve the efficiency and effectiveness of nutrition of plants • Quality of plant products. With sessions on: Nitrogen; Phosphorous; Micronutrients; Symbiosis; Membranes; Stress; Heavy Metals and Plant Breeding. In comparison with the previous conferences in this series more emphasis was placed on use of molecular techniques to clarify physiological mechanisms and processes, gene expression and regulation, as well as genetic marker assisted analysis. Significant of molecular genetic markers and other progress was reported in exploitation biotechnologies in breeding programmes.
