9. The cambium retains its normal position between xylem and phloem throughout the development of the knot, except opposite the broad rays. 10. Wedge-shaped masses of xylem are produced by the cambium ...

The center of a tree or shrub stem (from roots to trunk, branches, and twigs) is woody, composed of xylem cells that conduct water from the roots to the upper parts of the tree. That woody section is ...

Vascular cambium produces xylem (wood) and phloem, and together with the cork cambium, which produces a protective layer at the surface called phellem (cork), they provide thickness to plant organs.

We study genes that contribute to cell division activity in vascular cambium, the meristem between xylem (wood) and phloem. Understanding the regulation of the cambium activity enhancing factors might ...
