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