Although less visible than shoots, leaves and flowers, plant roots are critical to our lives. They provide the crops we eat with water, nutrients, a firm anchor and a place to store food. Roots are complex branching organs and show a wide variation in the way they grow through the soil to exploit the available resources.
The way that new lateral roots are formed and grow is key to this process. Lateral roots originate deep within the parent root and must emerge through intervening layers of tissues before entering the soil. Despite its importance to the integrity and architecture of the root system, little is known about the regulation of lateral root emergence. This question has fascinated, yet frustrated, scientists since the nineteenth century.
A paper appearing in Nature Cell Biology reveals for the very first time how lateral root emergence is achieved. It reports that new lateral roots reprogramme the cells that overlay them, causing them to separate and enabling the new root to emerge. In short, the scientists have discovered how new roots open the door to the world outside.
Professor Malcolm Bennett, Biology Director for the Centre for Plant Integrative Biology and Head of Division of Plant and Crop Sciences, said: ”In addition to providing new biological insight into lateral root emergence, we have a identified a large number of genes that control this process. This is really important because this may enable us to breed crops with improved root architecture in the future.”
The Centre for Plant Integrative Biology (CPIB) is funded by the Systems Biology joint initiative of the Biotechnology and Biological Sciences Research Council (BBSRC) and the Engineering and Physical Sciences Research Council (EPSRC) which has provided £27m for six specialised centres across the UK. The Division of Plant and Crop Sciences is one of the largest communities of plant scientists in the UK. Around 160 people work in the division, which welcomes visiting scientists from all over the world, reinforcing its reputation as a world-renowned centre.
This international collaboration involved more than 20 scientists from laboratories based in Belgium, France, Germany, Spain, Sweden, USA and UK.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
