Flourishing faster: How to make trees grow bigger and quicker

16.04.2015

Scientists at The University of Manchester have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the effects of climate change.

In the study, published in Current Biology, the team successfully manipulated two genes in poplar trees in order to make them grow larger and more quickly than usual.

Professor Simon Turner from the Faculty of Life Sciences led the research: "The rate at which trees grow is determined by the rate of cell division in the stem. We have identified two genes that are able to drive cell division in the stem and so override the normal growth pattern.

"Although, this needs be tested in the field, this discovery paves the way for generating trees that grow more quickly and so will contribute to meeting the needs for increased plant biomass as a renewable source of biofuels, chemicals and materials while minimising further CO2 release into the atmosphere."

The genes, called PXY and CLE, control the growth of a tree trunk. When overexpressed, making them more active than in their normal state, the trees grew twice as fast as normal and were taller, wider and had more leaves.

As well as the potential to increase biomass supplies for the growing biofuel and industrial biotechnology sectors, the discovery could help plants deal with the environmental consequences of climate change.

Professor Turner adds: "Our work offers the possibility we may be able to maintain a fast growth rate even in the face of adverse and changeable environmental conditions that all plants are likely to be faced with.

"Most plants, including crops, respond to adverse environmental conditions with lower growth rates that result in correspondingly lower yields. Understanding how the plants respond to environmental signals and to what extent we are able to manipulate them to override these signals is likely to be very important for continued improvements to crop performance. In future it may be possible that manipulating the expression of the PXY and CLE genes can override environmental signals that normally alter plant growth.

"This is something that needs to be tested in the field, but offers a potential way forward for what is one of the most pressing challenges of the day."

The team now plans to work with a forest products company to test their findings in the field.

The work builds on a previous study from 2010 in which the team identified the role of the genes involved, in the plant Arabidopsis.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
