Plants react sensitively to changes in their surroundings and possess the ability to adapt to them. They use the photoreceptor protein phytochrome B to see light and then regulate processes such as seed germination, seedling development, longitudinal growth and flower formation. A team led by Prof. Dr. Andreas Hiltbrunner from the Institute of Biology II at the University of Freiburg has recently conducted a study that shows that both proteins PCH1 and PCHL influence this receptors’ photosensitivity. The researchers recently published their findings in the journal Nature Communications.
