The IRT1 gene is responsible for most of the iron uptake activity in roots (Vert et al., Plant Cell 14 [2002]:1223-33). To determine the specificity of the IRT1 transporter in Arabidopsis plants, researchers measured the concentration of manganese, zinc, copper, and cobalt contained in wild-type and irt1-1 mutant plants. What conclusions about IRT1 specificity can you draw from the above data?
A) Under iron-deficient conditions, IRT1 is highly specific for Fe.
B) Under iron-deficient conditions, IRT1 is important for the transport of iron and copper.
C) IRT1 is important for the transport of iron and copper independent of iron concentration.
D) Under iron-deficient conditions, IRT1 is necessary for the transport of iron, zinc, manganese, and cobalt.
E) IRT1 participates in the transport of iron, zinc, manganese, and cobalt independent of iron concentration.
