About the Cover
On the Cover: The cover of this Focus Issue on Light Signaling illustrates the potent effect light can have on plants. The dramatic developmental responses of plants to light have long attracted the interests of plant researchers. For example, Darwin's seminal work in the late 1800s on phototropism showed that a signal (now known to be auxin), was transmitted between the site of light perception and the region of differential growth, and his contemporary, Julius von Sachs, showed that blue light was the most critical for eliciting phototropic curvature. However, detailed mechanistic understanding of light signaling remained elusive until photobiologists adopted molecular and genetic approaches, and Arabidopsis as a model system. The collection of papers in this Focus Issue exemplify the versatility of modern research on how light signals influence the physiology and development of plants. The cover image of phototropism in corn seedlings was provided by Roger Hangarter (Indiana University).
