HORST2 1 Key Laboratory of Crop Genetics and Physiology of Jiangsu Province, Yangzhou University, Yangzhou 225009, China; 2 Institute of Plant Nutrition, Leibniz University of Hannover, 30419 Hannover, Germany Abstract: For enhancement of micronutrient concentrations in edible parts of food crops, element uptake and partition in plants, especially in seeds, should be better understanded. Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is a recently developed technology for examining mineral elements distribution in plant tissues. By using this technique, we quanti- tatively measured distributions of manganese (Mn), copper (Cu), zinc (Zn), and phosphorus (P) in different parts of wheat see
