PHLOEM TRANSPORT IN TREES

Zero-calorie sugar delivery to roots

Nature Plants volume 3, pages 922–923 (2017)Cite this article

Subjects

Resistance to moving sugars from foliage to roots is high in trees, suggesting that the transport mechanism found in herbs might not work in trees. Now with new measurements of phloem structure and leaf turgor pressure, it has been shown that the Münch pressure-flow hypothesis can also explain sugar transport in tall trees.
