Sentences with word «phytochrome»

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.

Using a special method of spectroscopy, the researchers showed that the dark reversion of phytochrome B is almost completely suppressed when the amount of PCH1 or PCHL is increased, while the process is accelerated when PCH1 and PCHL are missing.

One protein called Phytochrome Interacting Factor 4 (PIF4) is crucial to coordinating a plant's response to elevated temperature by activating the genes that help the plant deal with heat stress.

The protein works like a kind of switch: the bright red light of sunlight activates phytochrome B, while it is inactivated by far - red light which is abundant in canopy shade.

Mammalian Expression of Infrared Fluorescent Proteins Engineered from a Bacterial Phytochrome

A union of independent proteins — red - sensing phytochrome and blue - sensing phototropin — the super-protein combines two already - great pieces into one fantastic whole that helps plants grow toward dim, filtered light.

Brassinosteroid, gibberellin and phytochrome impinge on a common transcription module in Arabidopsis

Rick (Washington University, St. Louis) is an outstanding scholar and mentor who has made distinguished and sustained contributions to three broad areas of plant biology: the ubiquitin - proteasome system, autophagy, and phytochrome structure and signaling.

Here we report the room temperature crystal structure of the chromophore - binding domains of the Deinococcus radiodurans phytochrome at 2.1 Å resolution.

Plants see red light using receptors in their leaves called phytochromes.

Phytochrome B measures the light spectrum, which varies depending on the surroundings.

Their theory is that the phytochrome protein in peppers and other plants is a biological light sensor that responds to red light, particularly far - red, which is beyond the range of human vision.

A phytochrome is a sort of light - activated switch: when irradiated with red light, it changes its conformation so that it is primed to detect far - red light, and when irradiated by far red it changes back to the form that is sensitive to red light.

In their study, the scientists have now found out that there are two proteins in the thale cress plant, PCH1 and PCHL, which bind to phytochrome B and influence the activity of the receptor.

By allowing the plants to regulate the change from the active to the inactive state, they can adapt the photosensitivity of the phytochrome B photoreceptor to different conditions.

The investigated proteins are called «phytochromes».

Nearly all his independent research relates to understanding light perception and signal transduction by the phytochrome superfamily of light absorbing molecules in plants and, more recently, in microbes.
