Fig. 4From: OsProT1 and OsProT3 Function to Mediate Proline- and γ-aminobutyric acid-specific Transport in Yeast and are Differentially Expressed in Rice (Oryza sativa L.)Uptake of 15N-labeled Pro by yeast 22△10α cells. Yeast cells expressing OsProT1 or OsProT3 were incubated with 1.5 mM 15N-Pro for 15 min and 30 min, and the 15N retained in the cells was subsequently measured. Values are means ± SD, n = 4Back to article page
