Understanding radial growth in plants
Today’s Video of the Day from the University of Cambridge describes how researchers are gaining a better understanding of radial growth in plants.
The vascular cambium is a thin, microscopic layer underneath tree bark that is responsible for all of the outward growth of wood and trees.
Despite the important role of the vascular cambium, very little was known about how it worked. To investigate, the scientists focused on stem cells.
The study revealed that early stage young phloem cells, which transport nutrients, initiate and organize the primary stage of radial growth.
