| This is the opposite of the situation in higher plants, where red light activates and far-red light inactivates phytochrome. |
|
| This macroscopically observable reaction was identified to be coupled with light-induced processes of the photoreceptor phytochrome. |
|
| The plant photoreceptor phytochrome exhibits remarkable structural and functional variabilities in the plant cell. |
|
| Light signalling pathways from both phytochrome and cryptochrome photoreceptors regulate clock components to achieve entrainment in plants. |
|
| As in other cryptogam species, the effect of polarized red light implies that phytochrome acts at the cell periphery. |
|
| Those genes included one for a light-sensitive plant protein called a phytochrome, which changes shape upon absorbing certain wavelengths of red light. |
|
| What they actually perceive is the length of the night, using their phytochrome system, which employs blue pigments in photoperiodic processes. |
|
| Moreover, it has been suggested that some of the reported blue-UV effects may have resulted from phytochrome instead of blue-UV photoreceptor action. |
|
| Also of interest is whether variation observed at the phytochrome loci in domesticated sorghum, or in particular races, is a result of human selection. |
|
| Green plants possess small amounts of a pigment called phytochrome that can exist in two forms. |
|
| These adaptative responses are known to be governed by reactions in which the light-sensitive pigment phytochrome plays a part. |
|
| The light stimulus is mediated by a sophisticated photoreceptor in plants known as phytochrome that is extremely sensitive to fluctuations in light intensity and light quality. |
|
| A single chromoprotein with triple chromophores acts as both a phytochrome and a phototropin. |
|
| One ancestor is the gene for a red receptor called a phytochrome. |
|
| Another example is phytochrome, a bilichrome pigment of blue colour, which, although present in very minute quantities in green plants, is indispensable in various photoperiodic processes. |
|
| Even very brief exposures to light absorbed by P660 delays flowering in some short-day plants otherwise geared to flower by previous exposure to light of such wavelength that only the P730 phytochrome is involved. |
|
| This pigment, called phytochrome, serves as a clock and calendar for the plant. |
|
| The plant photoreceptor phytochrome can sense the ratio of red and far-red light in its environment. |
|
| These levels may not have been sufficient to activate the phytochrome response and entirely inhibit etiolation. |

| Interaction between the effects of phytochrome and gibberellic acid on the senescence of Alstroemeria pelegrina leaves. |
|
|
|
| In the 1950s, BARC scientists discover phytochrome, a dual form plant protein that determines when a plant will start, or put off, flowering. |
|
| Natural bacterial phytochrome photoreceptors utilize low molecular weight biliverdin as a chromophore and provide many advantages over other chromophore binding proteins. |
