The management of phosphorus (P) in agricultural production represents an important issue for the twenty-first century and beyond (Sharpley et al., 1994; Brinch-Pedersen et al., 2002). Adequate soil available P is essential to optimal crop yields. After nitrogen, P is the second most common component of fertilizer, but both the production and use of P fertilizers, and application of P-rich manures, can have a negative impact on the environment and on water quality. A large fraction of the P taken up by plants during vegetative growth is translocated to developing seed. Therefore it is not surprising that the total amount of P annually stored in mature seeds of grain and legume crops is estimated to represent a sum equivalent to ~60% of the fertilizer P applied worldwide (Lott et al., 2000). Thus seed P represents an important bottleneck in the flux of P through the agricultural ecosystem. However, while fertilizer and manure P is applied to insure optimal yields, its...
