Plant Biology and Food Security

Increasing the yield of crop plants is a major facet of increasing food security, and one way to do this is from understanding plant biology. Once we understand the underlying biology, we can optimise those inputs key to plant growth, and minimise disruptive factors, as well as ensuring plants are resilient to potential climate changes. Within the Initiative, this is approached from the study of several aspects of plant biology: from the study of insect pests, and how they spread diseases; of efficient forms of photosynthesis, and of how epigenetically encoded variation can be exploited in breeding, as well as how RNA silencing can act in development. This theme also encapsulates work on optimising the extraction of lignocellulosic biofuels from plant waste, in order to relieve the food vs fuel dilemma, as well as work on archaeobotany and archaeogenetics, in the context of the broader archaeology of food.

Plant scientists call for rethink of GM crop regulation

19 Mar 2014 

In a report to the Council for Science and Technology, which advises the Prime Minister on science policy, the scientists warn that unless GM crops are regulated at national, rather than at EU level, European agriculture could suffer because it will be unable to adopt GM crops.
