Phytochromes are a class of photoreceptor proteins found in plants, bacteria and fungi. They respond to light in the red and far-red regions of the visible...

under one condition. Phytochrome comes in two forms: Pr and Pfr. Red light (which is present during the day) converts phytochrome to its active form (Pfr)...

of photoreceptors: phytochrome, cryptochrome, a UV-B photoreceptor, and protochlorophyllide a. The first two of these, phytochrome and cryptochrome, are...

(2011-01-25). "Phytochromes inhibit hypocotyl negative gravitropism by regulating the development of endodermal amyloplasts through phytochrome-interacting...

spectrum of chlorophyll, and it is perceived by the plant photoreceptor phytochrome. However, some organisms can use it as a source of energy in photosynthesis...

process from photosynthesis where light is used as a source of energy. Phytochromes, cryptochromes, and phototropins are photochromic sensory receptors that...

PhyA is the phytochrome responsible for causing these architectural changes of the lateral root. Research has also found that phytochrome completes these...

Other examples of chromoproteins include other hemochromes, cytochromes, phytochromes and flavoproteins. In hemoglobin there exists a chromoprotein (tetramer...

combination of responses from phytochromes and cryptochromes allow the plant to respond to various kinds of light. Together phytochromes and cryptochromes inhibit...

(photomorphogenesis). In Arabidopsis, phytochrome B is the predominant photoreceptor that regulates SAS. Phytochromes exist in two forms: PR and PFR. It...
