During salt stress condition in Arabidopsis, which of the following antiport proteins are used?

(a) AvPI and AtNHX

(b) AvPI and AtDBF

(c) AvPI and AvPII

(d) None of the mentioned

This question was posed to me in an international level competition.

I would like to ask this question from Movement of Substances Across Cell Membranes topic in portion Cellular Membranes of Cell Biology

Best answer
Right choice is (a) AvPI and AtNHX

The best I can explain: AvPI (Arabidopsis vacuola protein I) and AtNHX (Arabidosis transporting H^+ ion) are the antiport proteins present on the membrane of vacuole. During salt stress condition, there is an increase in Na+ ion in the cell, which leads to acidity in cell and may be harmful to plants. These antiport transport Na^+ ion into the vacuole from cytoplasm coupled with the transport of H^+ ion from vacuole to cytoplasm. This result in reduction of Na+ concentration in cytoplasm and reduction of acidity in salt-stress condition.
