英文摘要	A light-rare-earth-element (LREE)-binding peptide was isolated from LREE hyperaccumulator Dicranopteris dichotoma leaves and characterized in terms of molecular weight and ultraviolet absorption spectrum. The molecular weight of the LREE-binding peptide was determined to be 2208 Da by matrix-assisted laser-desorption ionization-time of flight mass spectrometry (MALDI-TOFMS). The characteristic ultraviolet absorption spectrum of the peptide was observed at 220-300 nm, suggesting that the peptide chain contained aromatic amino acids. Compared to the unique features of the phytochelatins with a low absorption at 280 nm, the LREE-binding peptide is unlikely to be a typical phytochelatin. The present study suggests that the LREE-binding peptide is probably a natural peptide in D. dichotoma, and it may play an important role in hyperaccumulation of LREEs.
