Mass spectrometric and microscopic analyses are fundamental analytical technology in plant science and sustainable resource science. Our unit develops and executes the analyses based on mass spectrometry for the study of plant metabolome and hormonome and on microscopy for the ultrastructural observation of the plant cells.
