Phototropism occurs as auxins move laterally across the shoot tip away from light, stimulating growth on the unilluminated side, causing the shoot to grow asymmetrically towards the light.
La phototropisme se produit lorsque les auxines bougent latéralement sur la pointe de la pousse, loin de la lumière, stimulant la croissance du côté non éclairé et faisant ainsi pousser la pousse de manière asymétrique vers la lumière.
