Sensing the light 🌱💡 📚 Phototropism - the ability of the plant to re-orient the shoot growth towards a direction of the light source. 🌿 Phototropism underlies the ability of plants to optimize their photosynthetic capacity. 🔬 Phototropism responses in higher plants is mediated by phototropins - a specific class of photoreceptor proteins (flavoproteins). Phototropins are blue light (390–500 nm)-activated kinases that regulate also other biological processes, such as stomatal opening, and lig
