Figure Lengend Snippet: FIG. 6. Functional characterization of AtOPT3. A, hybridization of an 600-bp AtOPT3 cDNA probe, corresponding to the 3-terminal exon, to RNA extracted from Arabidopsis roots of plants grown in control conditions (Ctl), copper (-Cu), manganese (-Mn), zinc (-Zn), and iron (-Fe) deficiency. The ethidium bromide-stained RNA gel is shown for quantification. B, growth of ctr1 expressing AtOPT3 on YPG-Ura plates supplemented with 10 M CuSO4 compared with the mutant transformed with the vector alone. C, growth of smf1 expressing AtOPT3 on manganese-limited medium, with and without 1 mM EGTA compared with the growth of the mutant transformed with the vector alone.
