The use of genetic engineering to increase productivity in rice

As global demand for food increases, plant geneticists are working to increase the productivity of rice by investigating gene switches which control development of vascular tissue. The work is at an early stage, and involves difficult extraction of the meristems from the young plants in order to look at the gene expression in the developing tissues. The work is important because populations are increasing, fertilisers are increasingly expensive and rainfall is increasingly unpredictable.
