Method of analyzing metabolism for plant, method of producing labeled plants, labeled plants, and method of measuring NMR for plants

摘要

The present invention provides a method of analyzing metabolism of a plant in which measurement sensitivity for nuclides such as ¹³C and ¹⁵N having low natural abundance ratios is improved using NMR. A labeled plant uniformly labeled with a stable isotope is produced by providing the plant with a nutrition source labeled with at least one type of stable isotope while growing the plant from a seed or a germinating seedling. The metabolism of a biological substance in the plant is analyzed based on NMR data of a biological substance that contains the stable isotope. The NMR data is acquired by performing NMR measurement on a body of the labeled plant, a portion of the body, or an extract.
