posted on 2023-05-18, 00:26 authored by Wu, J, Wei, Z, Zhao, H, Li, H, Hu, FThis study focuses on the role of amino acids in xylem sap of tomato grown in hydroponics in a medium supplemented with a series of concentration of La and Y. Eighteen amino acids in xylem saps were identified and measured by reversed-phase highperformance liquid chromatography. The main amino acids in xylem sap samples of the tomato are histidine, tryptophan, aspartic acid, and glutamic acid. The concentration of glutamic acid in xylem sap significantly increased in the La and Y treatment compared to the control. By analyzing the correlation between concentrations of amino acids and concentrations of La and Y in the xylem saps, we considered that the glutamic acid in xylem saps seemed to participate in the long-distance La and Y translocation processes, and histidine did not relate to xylem La and Y transport of tomato. The role of other amino acids which was excreted by tomato has not been demonstrated in the long-distance transport of La and Y in the xylem.
