Rice is a cereal grain, it is the most important staple food for a large part of the world’s human population, especially in Asia and the West Indies. It is the grain with the second-highest worldwide production, after maize (corn), according to data for 2010. Since a large portion of maize crops are grown for purposes other than human consumption, rice is the most important grain with regard to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by the human species Scientists have now pinpointed a gene that enables rice plants to produce around 20% more grain by increasing uptake of phosphorus, an important, but limited, plant nutrient. The discovery unlocks the potential to improve the food security of rice farmers with the lowest value phosphorus-deficient land allowing them to grow more rice to add to global production, and earn more.
