  • One type, called phytochromes, are sensitive to red and far-red light and play a major role in the making of chloroplasts and the growth of the stem, said Chen, who is the first author on the study.

  • Plants use phytochromes, a group of protein photoreceptors to sense different wavelengths.

  • But when phytochromes are activated by light, they destroy the PIFs, clearing the way for chloroplast development.

  • One of the first things that happens when the plant detects light is that these phytochromes move from the cell's cytoplasm to its nucleus, where the genes are kept.

  • Steve Kay got his start in plant phytochromes and is the Mister Big Science of chronobiology - always the first one to introduce new molecular techniques into the field (e.g., the first one to use DNA-chips some years ago).

  • Although the phycocyanobilin (PCB) chromophore is attached to Cys-259 as expected, paralleling the situation in plant phytochromes but contrasting to that in bacteriophytochromes, the

  • In any case, the new structure gives new insights into how phytochromes are constructed and how they might work, information which help us to understand how phytochromes regulate plant development.

  • Unfortunately, how exactly phytochromes work is still only partly understood, even though numerous laboratories worldwide devote their energies towards the question.

  • It might be that phytochromes are connected to related signalling systems.

  • Up to 1996 it had been thought that phytochromes only existed in plants, but at that time Jon Hughes - then a postdoc at the Free University of Berlin and now Professor of Plant Physiology at Giessen - and colleagues discovered the first prokaryotic phytochrome in the photosynthetic cyanobacterium Synechocystis 6803.
