Two photon-linked biodiversity (1)

Excerpt: Photochromic photoreceptors, called phytochromes, perceive changes in the ratio of red and far-red light. The perceived changes help to control light-activated microRNA biogenesis in the context of the shade avoidance reaction of plants. If plants avoid the shade, they grow in the amount of light that is readily available. Convergent evolution of SWS2 opsin Two photon-linked biodiversity (1)
