Sample Questions Q1) Give two reasons that relatively few plants thrive in bogs. Q2) Iron shortage is the most common human nutritional deficiency in the world.Plants are the major source of iron in most diets,so researchers are interested in understanding their mechanism of iron intake and in developing iron-rich crops.Recently,researchers showed (Vert et al.,IRT1,an Arabidopsis transporter essential for iron uptake from the soil and for plant growth.Plant Cell 14 [2002]:1223-33)that under iron-deficient conditions,the IRT1 gene is responsible for most of the iron uptake activity in roots.To demonstrate the importance of IRT1 for iron accumulation,researchers measured leaf iron content in irt1-1 mutants containing deactivated IRT1.Mutant plants were grown in iron-poor soil (irt1-1 in graph)and soil rich with iron (irt1-1 +Fe in graph).Wild-type (WT)plants grown in iron-poor soil were used as a control.Which of the graphs represent the data researchers might have received in their experiment?

Sample Questions Q1) Figure 39.3 is a Northern blot showing the expression of Myb mRNA in cultured aleurone layer cells that were treated with gibberellin versus control cells that were not treated with gibberellin.Only the gibberellin-treated cells expressed the Myb mRNA,but the Myb mRNA was not detectable until 6-12 hours after gibberellin application.Why did it take so long? A)Gibberellin had to bind to a receptor and initiate a signal transduction cascade that,in turn,had to activate a transcription factor that triggered the transcription of the Myb gene. B)Gibberellin had to diffuse into the aleurone layer cells and be metabolized in order to trigger activation of a transcription factor that triggered transcription of the Myb gene. C)Gibberellin had to enter the cells and find the Myb gene among the large plant genome. Q2) Why would the researchers study the association between cell death,nitric oxide,and reactive oxygen intermediates?
