Plants have better vision than humans, even without eyes
Like people, plants also have a cycle of dream-vigilia that we call circadian rhythm. Cryptochromes are the proteins in crops and animals that help regulate sleep cycles. Now a recent study has found that Plants, thanks to these specific receptors, can react to bluish tones, making them perceive all wavelengths of light and even have better vision than humans themselves.
“The plants they can see much better than us, “says Itzan Shabek of the Department of Plant Biology of the Faculty of Biological Sciences, co-author of the work published in the journal Nature Communications Biology.
As you can see”?
Plants do not have organs dedicated to detecting light, like our eyesBut they do have a wide variety of dedicated receivers that can detect almost all wavelengths. One of them are blue light photoreceptors called cryptochromes, responsible for key processes such as seed germination, flowering time or circadian clock. When cryptochrome detects an incoming photon, it reacts in a way that triggers a unique physiological response.
Scientists studied the specimen Arabidopsis thaliana, considered a model plant. It has a small genome, grows rapidly and produces many seeds, characteristics that make it a good example for study and analysis.
Thus, using the advanced light source x-ray at the Lawrence Berkeley National Laboratory, managed to identify the construction structure of the cryptochrome-2.
