question 58

Multiple Choice

One way to improve crop productivity is to modify flowering time.This can allow for multiple growing seasons in one year,and can also increase grain production because a smaller plant has lower resource needs.You are approached by an agricultural company that wants to create an early-flowering transgenic plant.Using your knowledge of Arabidopsis genetics,which genetic modifications would you suggest?

• A)Inhibition of the embryonic flower (EMF)gene or overexpression of the LEAFY (LFY)gene would work.
• B)Inhibition of the LEAFY (LFY)gene or overexpression of the embryonic flower (emf)gene would work.
• C)Inhibition of either the embryonic flower (emf)gene or the LEAFY (LFY)gene would work.
• D)Early flowering is not possible in Arabidopsis,and is not likely to be possible in other plants.
