A researcher discovers a pea plant mutant having PIN proteins that are located on the apical (not basal) sides of cells in the shoot apical meristem. What processes would this affect?

Question

Quizplus · Accepted Answer

PIN proteins are crucial for the polar transport of auxin, which influences various developmental processes in plants, including the development of xylem and phloem, as well as the establishment of procambial cells. If PIN proteins are mislocalized, all these processes could be affected due to disrupted auxin distribution.
