Researcher grows roots on upper part of plant

31.10.2008
The molecular cell biologist Pankaj Dhonukshe from Utrecht University has succeeded in growing roots on plants at places where normally leaves would grow.

This important step in plant modification can be highly beneficial for improving crop yields and efficiency in the agricultural sector. This research was largely carried out in collaboration between Utrecht University (The Netherlands) and Ghent University (Belgium) with help from scientists in Japan, USA and Switzerland. The results of this research appeared as an advance online publication of the weekly science journal Nature on 26 October 2008.

The plant hormone auxin plays a crucial role in coordination of stem cells and organ formation in plants. It promotes the formation of roots from stem cells and coordinates the growth of leaves and fruits. Auxin is produced mainly in young leaves, or shoots, and is then transported from one cell to the next towards the basal region of plant ultimately leading towards root formation.

Roots above ground
Pankaj Dhonukshe discovered a molecular switch to alter the auxin transport. By turning on the switch, Dhonukshe was able to reduce the extent of auxin transport towards the roots. The hormone then began to accumulate at the places in the young leaves where it is produced and roots began to emerge here where normally leaves would grow.
Increased yields
These results are an important step in our understanding of the way plants grow and create novel future possibilities to modify the positioning of various plant organs such as roots, fruits and leaves. This specific manipulation of plant architecture promises to enhance yield-traits and crop harvesting. Molecular switches are particularly interesting for influencing plant forms, because utilization of traditional plant refinement approaches has certain limitations. The Utrecht research group is currently examining further interesting possibilities in this area.
Collaborative Research
Dhonukshe carried out the developmental biology research at Utrecht University, and the cellular biology research in cooperation with Ghent University.
Life Sciences and Biocomplexity
Utrecht University has organised its top-level research into fifteen focus areas, which are intended to promote high-quality research and contribute to solving major problems in society. The study described above falls under the category ‘Life Sciences and Biocomplexity’, in which research is being carried out into all the processes in the cell from the molecular scale to the creation of multi-celled organisms and the interaction among cells. Genomics and proteomics form an important part of this area.

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
