The activity of uridine diphosphate-d-glucose-4-epimerase in cambial tissue and differentiating xylem isolated from sycamore (Acer pseudoplatanus) trees

摘要

It is demonstrated that, contrary to another report, UDPGlc-4-epimerase is present in both sycamore (Acer pseudoplantanus) cambium and xylem tissue. It is suggested that the enzyme may be localised in the non-lignifying primary-walled cells common to both tissue fractions.
