How plants stabilize their water pipes

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while simultaneously providing stability. The so-called xylem, also known as wood, is a network of hollow cells with extremely strong cell walls that reinforce the cells against the mechanical conflicts arising from growing tall. These walls wrap around the cells in filigree band and spiral patterns. So far, it is only partly known, how these patterns are created. Scientists from the Max Planck Institute for Molecular Plant Physiology in Golm/Potsdam and from Wageningen University and their colleagues study the formation of such reinforced and patterned cell walls. ....

Wood formation can now be followed in real-time - and possibly serve the climate and builders of tomorrow

A genetic engineering method makes it possible to observe how woody cell walls are built in plants. The new research in wood formation, conducted by the University of Copenhagen and others, opens up the possibility of developing sturdier construction materials and perhaps more climate efficient trees.

The ability of certain tree species to grow taller than 100 meters is due to complex biological engineering. Besides needing the right amounts of water and light to do so, this incredible ability is also a result of cell walls built sturdily enough to keep a tree both upright and able to withstand the tremendous pressure created as water is sucked up from its roots and into its leaves. ....
