The xylem vessels are the main route for transporting materials and information from the roots to the shoot. This study elucidated the mechanism controlling the production of a xylem sap protein, XSP30, in cucumber root, and characterized the lecin activity of XSP30. In Part I, the expression of the gene encording XSP30 in roots of cucumber (Cucumis sativus L.) was shown to be dependent on exposure of the aboveground tissues to light, Gene expression of XSP30 was barely detected in the roots of 4-day-old seedlings, but expression increased with subsequent seedling growth. ・・・, 2003, Includes bibliographical references}, school = {筑波大学, University of Tsukuba}, title = {Production and activity of xylem sap lectin in cucumber}, year = {2004} }
