Growing crops to cope with climate change

20.01.2006


Scientists at the UK’s leading plant science centre have uncovered a gene that could help to develop new varieties of crop that will be able to cope with the changing world climate. Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the John Innes Centre in Norwich have identified the gene in barley that controls how the plant responds to seasonal changes in the length of the day. This is key to understanding how plants have adapted their flowering behaviour to different environments.



The John Innes Centre researchers have discovered that the Ppd-H1 gene in barley controls the timing of the activity of another gene called CO. When the length of the day is long enough CO activates one of the key genes that triggers flowering. Naturally occurring variation in Ppd-H1 affects the time of day when CO is activated. This shifts the time of year that the plant flowers.

Dr David Laurie, the research leader at the John Innes Centre, said, "Growing crops will become more difficult as the global climate changes. The varieties of crops grown in the UK are suited to the soil, seasons and traditional cool, wet summers. Later flowering in barley means it has a longer growing period to amass yield. If British summers get hotter and drier we will need types of wheat, barley and other crops that flower earlier, like Mediterranean varieties, to beat summer droughts. However, new varieties will need to be adapted in all other ways to UK conditions. "


With the new knowledge about the workings of barley researchers and plant breeders will find it easier to select variations that will thrive in the UK environment but will also flower earlier, coping with hotter summers.

Dr Laurie commented, "Although our research has been on barley we know from observation that other crops show similar variation in the way they respond to the lengthening of the day in springtime. We are confident that we will find equivalent genes in other key crops."

Professor Julia Goodfellow, BBSRC Chief Executive, said, "Climate change presents a huge challenge for the world. Although every effort must be concentrated on reducing the impact of human activity on the environment, science should also be answering questions about how we can live in an altered climate. Research such as this helps to present answers to some of these problems."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
