Description: Das Projekt "Molecular physiology of the regulatory interaction between above- and below-ground nitrogen nutrition of carnivorous model plants" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Institut für Forstbotanik und Baumphysiologie, Professur für Baumphysiologie durchgeführt. Carnivorous plants have evolved in environments where light and water are abundant, but soil-macro-nutrients such as nitrogen, phosphorus, and potassium are severely limiting. As a consequence, nutrient levels in carnivorous plants are low and, despite their herbaceous habit, carnivorous plants are more similar to evergreen shrubs and tree with respect to their leaf nutrient contents. A meta analysis of studies that tested if carnivory improved the growth of carnivorous plants indicates a significant positive effect of prey addition on plant growth, but also showed that the additional nutrient gain from carnivory is less valuable in a relatively nutrient-rich environment. This observation resembles the interaction of atmospheric and pedospheric nitrogen sources in conifer seedlings and suggests a regulatory interaction between above- and below-ground nitrogen sources of carnivorous plants.
