摘要: Organisms acclimate to a continually fluctuating nutrient environment. Acclimation involves responses specific for the limiting as well that are more general and occur when an organism experiences different stress conditions. Specific enable organisms efficiently scavenge may involve induction of high-affinity transport systems synthesis hydrolytic enzymes facilitate release from extracellular organic molecules or internal reserves. General include changes in cell division rates global alterations metabolic activities. In photosynthetic there must be precise regulation activity since severe limitation prevents continued growth, excitation pigments could result formation reactive oxygen species, which can severely damage structural functional features cell. This review focuses on ways eukaryotes assimilate macronutrients nitrogen, sulfur, phosphorus, mechanisms govern assimilatory Also discussed molecular macronutrient elicitation those through integration environmental cellular cues.
