−
−	* Seed extracts of lpa mutants were subjected to HPLC analysis to determine if the other inositol phosphates were aVected by the mutation. Comparison to wild-type Nipponbare and inositol phosphate standards revealed that N15- 186 seeds are signiWcantly reduced in PA and inositol monophosphate while exhibiting an increase in Pi (Fig. 1). No signiWcant accumulation of other inositol phosphate intermediates (InsP2 to InsP5) was detected under the conditions used. The HPLC elution proWle of N15-375 showed an increase in Pi and a decrease in PA, but no other signiWcant changes were observed (Fig. 1).

−	* The GC–MS analysis revealed that the myo-inositol content, as well as those of other sugars (glucose, fructose and galactose), was increased in the N15-186 mutant compared to the wild-type (Fig. 2). The myo-inositol content of N15-186 seed was ninefold greater than wild-type, while the other sugars examined were 2–3 fold higher. In contrast, the myo-inositol content of N15-375 mutant seeds did not diVer from wild-type.
