How plants counteract against the shade of larger neighbors

Plants that "lose the battle" during competitiveness for light because they are shaded by larger neighbours, counteract. They adapt by rapid shoot elongation and stretch their leaves towards the sun. The molecular basis of this so-called shade avoidance syndrome had been unclarified to date. Research scientists from the Utrecht University in the Netherlands and the Ruhr University in Bochum have now been able to unravel a regulation pathway. A specific transport protein (PIN3) enables the accumulation of the plant hormone auxin, which plays an important role during this adaptation process, in the outer cell layers of the plants, thus enhancing the growth process.
