The idea of addressing the problem of the genetic specificity of mineral nutrition at an international level arose four years ago in a proposal for this topic to be included in the program of the II Congress of the Federation of European Societies for Plant Physiology (FESPP) as a separate section. The Organising Committee of the II Congress of FESPP which was held in Santiago de Compostella in 1980 arranged a special session and it was clearly successful. A special scientific meeting where the genetic aspects of plant nutrition in their widest sense could be presented and discussed comprehensively appeared to be necessary and that is how this Symposium came to be organized by the Serbian Academy of Sciences and Arts. Much progress has already been achieved in this field, and bearing in mind the importance of this problem, particularly at the present moment, it is necessary for us both to acquaint ourselves with what has been achieved so far, and even more to direct attention and effort to the fundamental problems for the future.

The 2nd International Symposium on Structure and Function of Roots or- ganised by the Slovak Academy of Sciences was held in Bratislava in early September 1980 and continued the theme ofits 1971 predecessor at Tatranska Lomnica. The symposium started with 'structural characteristics of roots in relation to the process of growth'. The approach was notable for the way in which it brought together cytologists, electron microscopists and physiologists to discuss pro- blems of common interest and set the scene for a muItidisciplinary approach to the remainder of the Symposium. Metabolie aspects of roots under normal conditions and after being exposed to stress received considerable attention, together with interesting contributions concerned with responses of roots to gravity. The session on water movement provided a useful balance between theoretical papers on the one hand and the resuIts ofthe use ofnew experimental approaches to the problem on the other. The Symposium continued with the examination of factors affecting the transport 01' ions into and across roots, particular attention focussing on metabolie aspects concerned with delivery ofions to the shoot.The problems associated with coordinating the separate functions 01' the root were introduced by a group ofpapers, again supported by contributions in which new experimental methods were described.

This volume presents the proceedings of the Second International Sym posium on Genetic Aspects ofPlant Minerai Nutrition, held in Madison, Wisconsin in 1985. The mechanisms by which plants acquire, transport and utilize essential minerai nutrients are highly complex. The means by which plants either exclude or tolerate ions of metals toxic to plants are equally complex. The first symposium attempted to convene research scientists con cerned with minerai nutrition for the purpose of exploring the kinds of minerai nutrition phenomena identified as being under genetic contro!. The first symposium also placed much emphasis on research to which genetic intervention might be applied. At the second symposium more papers were presented on genetic and breeding research, a long-term objective of the first symposium. The second symposium also included biotic interactions under genetic con trol that either enhanced or impeded ion uptake, e.g. mycorrhizae and nitrogen fixing bacteria. This continuing dialogue is essential for a research area the complexity of which is due to its interdisciplinary nature.
