Review: Stem cells of the vascular cambium
Plant Science Research WeeklyVascular cambium cells are meristematic cells responsible for secondary growth. Lineage tracing studies in Arabidopsis and poplar show the presence of single bifacial stem cells in each radial cell file that produce xylem inwards and phloem cells outwards. In a recent review, Wybouw et al. discuss the…
