| Research Abstract |
Effects of nutrient deficiency and aluminum toxicity stresses on plant ionome, all the mineral nutrient and trace elements found in an organism, were investigated. Nitrogen, phosphorus, and potassium deficiencies greatly changed ionome profile in plant. Among analyzed elements, changes in concentration of molybdenum and cesium were noticeable. It was expected that increase in molybdenum concentration under nitrogen deficient conditions could be related to nitrogen-fixing microorganisms. Aluminum stress also affected ionome profile in plant
