title: [Plant adaptation to nitrogen availability].
abstract: Nitrogen is an essential macronutrient for plant development and productivity. The adaptation toward changes in nitrogen availability in the soil is crucial for the immobile plant. Nitrate is the primary nitrogen source in temperate climate. Nitrate transport and assimilation are discussed with emphasis on the adaptation to nitrogen starvation. The integration of nitrogen metabolism with primary and secondary metabolism and the homeostasis with other nutrients are discussed. However, nitrate is not only a nutrient, but also a signaling molecule acting on multiple levels. The molecular players involved in the regulatory network are discussed.
