Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals. The findings could help current efforts to improve existing crop varieties.
Technology Strategy Board: Engineering solutions to enhance agri-food production
COMPETITION FOR COLLABORATIVE R&D FUNDING JULY 2013
The Technology Strategy Board, together with the Department for Environment, Food and Rural Affairs (Defra), the Biotechnology and Biological Sciences Research Council (BBSRC), and Scottish Government, is offering up to £13m for businesses to develop engineering solutions across the agri-food supply chain.
New research published in Nature by Dan Bebber, Mark Ramotowski and Sarah Gurr (a past member of our Food Research Network) shows a shift towards the poles in observations of hundreds of pests and pathogens, which supports the hypothesis of global warming-driven pest movement.

Science will be publishing an article by the authors on sustainable intensification on July 5th 2013. If you are interested in reading it, please check back here then, or sign up to our newsletters (FCRN and Future of Food).
Fertilisation of grasslands significantly reduces their ability to cope with changing conditions even when they contain a diverse mix of plants, finds a global study involving Oxford University. The research, published this week in Nature, showed that diverse grasslands were more stable over time but that this effect was weakened when the plots were artificially fertilised.
"More diverse areas are generally more stable because different plants will benefit from different things at different times," said Professor Andrew Hector of Oxford University's Department of Plant Sciences, senior author of the study. "To take a simple example, if you have plants that thrive in heavy rain and plants that prefer lighter rain in the same field, then the total amount of plant matter in the field in a given year will be less dependent on rainfall as both types will balance each other out."
Fertilisers are known to drive down grassland diversity over time, but this study found that fertilised plots were less stable even before their diversity decreased. This effect was not expected based on previous results. As fertilisation boosts total yields, it was expected to increase short-term stability by making small variations less significant. However, the study found that fertilisation disproportionately increased yearly variations in yield, particularly in the most diverse grasslands.
In March 2015, Securing Water for Food announced its third call for innovations. This $12.5 million call for proposals focuses on identifying market-driven, low-cost, and scalable solutions that will enable us to improve water efficiency and wastewater reuse; enhance water capture and storage; and reduce the impacts of salinity on aquifers and food production.
