physiological function | enzyme overexpression leads to higher vacuolar proton currents and vacuolar acidification. After 3 d in salt-untreated conditions, enzyme-overexpressing leaves show a drop in photosynthetic capacity, plasma membrane depolarization and eventual leaf necrosis. Salt, however, rescues enzyme-hyperactive cells from cell death. Under normal growth conditions, plants need to regulate the enzyme activity to avoid hyperactivity and its negative feedback on cell viability | Nicotiana benthamiana |
