Growth of wild-type (Wt) versus transgenic plants expressing psNTP9 in the presence of exogenous nucleoside phosphates. A, Representative 3-week-old Arabidopsis plants grown with three different treatments compared with Murashige and Skoog medium (MS) alone. B, Plants from the treatments were grown for 17 d and then weighed. All treatments were cross-analyzed for significance in a Student's t test. Bars marked by an asterisk differ significantly from those without an asterisk (n > 20 for all groups; P < 0.05; error bars = se).
