IPR037766 is a Protein FAR-RED ELONGATED HYPOCOTYL 1.
<p>This entry represents a group of plant proteins, including FHY1 (At2g37678) from Arabidopsis. Phytochrome A (phyA) is the photoreceptor in Arabidopsis that mediates the far-red light high radiance response. AtFHY1 is a key regulator of far red/red (FR/R) spectrum-specific responses by regulating phyA shuttling from the cytoplasm to the nucleus and by directly regulating the expression of some target genes. AtFHY1 phosphorylation is induced by the R signal, is part of the FR/R spectrum sensing mechanism that ensures its optimal response to specific light quality [[cite:PUB00087580]]. AtFHY1 also has an independent role in gene modulation and plant development under far-red light [[cite:PUB00087581]].</p> <p>This entry also includes FHL (FHY1 Like). FHL is essential for light-regulated PHYA nuclear accumulation and subsequent PHYA phototropic signaling processes [[cite:PUB00087583], [cite:PUB00087584], [cite:PUB00087585]]. The transcription of FHY1 and FHL are controlled by FHY3 (Far-red elongated HYpocotyl 3) and FAR1 (FAr-red impaired Response 1), a related pair of transcription factors [[cite:PUB00087582]].</p>

| Biological process | Response to red or far red light | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a red or far red light stimulus. Red light is electromagnetic radiation of wavelength of 580-700nm. Far red light is electromagnetic radiation of wavelength 700-800nm. An example of this response is seen at the beginning of many plant species developmental stages. These include germination, and the point when cotyledon expansion is triggered. In certain species these processes take place in response to absorption of red light by the pigment molecule phytochrome, but the signal can be reversed by exposure to far red light. During the initial phase the phytochrome molecule is only present in the red light absorbing form, but on absorption of red light it changes to a far red light absorbing form, triggering progress through development. An immediate short period of exposure to far red light entirely returns the pigment to its initial state and prevents triggering of the developmental process. A thirty minute break between red and subsequent far red light exposure renders the red light effect irreversible, and development then occurs regardless of whether far red light exposure subsequently occurs. |
