Histo-differentiation and molecular biology of developing cereal endosperm

Abstract

AbstractTo elucidate the molecular aspects of cereal endosperm development, a good understanding of the histo-differentiation process is necessary. Reviewing the extensive history of lightand electron-microscopic investigations has revealed similarities between cereals with respect to cell ontogeny. Thus, using barley as a model and taking into account many developmental mutants in this and other species, a model for endosperm differentiation is proposed. Based on this model, molecular studies on endosperm gene-regulation are discussed and the available techniques for further investigations are considered.
