Inhalt
- Results
- Growth response of maize seedlings to low night temperature, low N and low P stress
- Effects of low temperature, low N and low P stress on photosynthetic gas exchange
- Ion balance of low temperature, low N and low P stressed leaves
- Metabolite profiles of low temperature, low N and low P stressed leaves
- Transcript profiles of low temperature, low N and low P stressed leaves
- Effects of low temperature, low N and low P stress on transcripts of primary C, N and P metabolism of source leaves
- Discussion
- General impact of low temperature, low N and low P stress on metabolite and transcript profiles
- Ion balance of stressed leaves is regulated in a nutrient specific manner
- Phosphorus deficiency causes very distinct disturbances in carbon assimilation and energy metabolism
- C partitioning is characterized by a shift towards starch under cold and low N stress, but a preference for sucrose under low P stress
- Nitrate and amino acid metabolism adjust to demand under low temperature, low N and low P stress
- Control of phosphate homeostasis under stress depends on transcriptional regulation of a specific set of genes
