International units, μmol PO43− released min−1 mg−1 total protein. Data are means ± SEMs for replicate reactions from three independent assays. Different letters within columns indicate that the means differ significantly (P < 0.05).

b

Fold increase between pTD003 (rPhyA+)- and pTD882 (empty-vector)-transformed cultures. Data are means ± SEMs for replicate reactions from three independent assays. Different letters within columns indicate that the means differ significantly (P < 0.05).
