  1. a The treatments are described in 'Materials and Methods'.
  2. b Radioactivity transfers to the distal organs were detected after 90 min of incubation. Values are expressed as % of total radioactivity. Average ± SD (n = 4) was determined in three independent experiments.
  3. * Statistical analysis performed by ANOVA reveals significant difference with wild-type -Pi treatment (P < 0.005).
  4. Statistical analysis was performed using JMP 7 software.
