Phosphorus remobilisation during grain filling in rice

摘要

P hosphorus (P) is applied to crops to ensure high yields but adds to costs and contributes to water eutrophication. Most P in cereals is in harvested grain removed from fields. Improving plant P recycling and/ or reducing the P in grains may overcome this; however, the physiology and molecular mechanisms of P remobilisation from veg- etative tissues to developing grains must be better understood.
