Seed longevity: Survival and maintenance of high germination ability of dry seeds

The seed constitutes the main vector of plant propagation and it is a critical development stage with many specificities. Seed longevity is a major challenge for the conservation of plant biodiversity and for crop success. Seeds possess a wide range of systems (protection, detoxification, repair) allowing them to survive in the dry state and to preserve a high germination ability. Therefore, the seed system provides an appropriate model to study longevity and aging. To cite this article: G. Rajjou, I. Debeaujon, C. R. Biologies 331 (2008). (C) 2008 Academie des sciences.
