1. The phytochrome molecule is the photoreceptor used by plants to sense environmental red and far-red light changes, which are vital to direct growth and development.

2. Interactions within a network of UV-B, cryptochrome and phytochrome signaling pathways regulate CHS expression.

3. Relation between phytochrome action modes and possible multiple pathways for phototropic signal transduction was analyzed based on the experiment results.

4. Here, we revealed multiple action points for each phytochrome in the critical daylength response of florigen expression by using single and double phytochrome mutant lines of rice.

5. Day length is sensed by phytochrome in the young leaves, suggesting that a hormone is involved in transmitting the signal to the meristem.

6. While the expression amount for phytochrome genes were consistent among different transformants of transgenic rice.

7. Therefore, each phytochrome gene of rice has distinct roles,[sentencedict.com] and all of the phytochrome actions coordinately control the critical daylength response of florigen expression in rice.

8. It was indicated that phytochrome is the photoreceptor of female photoperiod-sensitive sterility in PFSR.

9. The study of phytochrome and its signal transduction pathway is a topic of central issue in cytobiology, developed biology and molecular biology.

10. To adapt to the surrounding environment, plants constantly monitor and respond to changes in the red and far-red regions of the light spectrum through the phytochrome family of photoreceptors.

11. Although people have hardly studied effects on alfalfa fall dormancy of phytochrome and plant hormone so far, this paper brought forward prospects of research at this aspect.

12. In this article, the molecular properties, the physiological functions and the signal transduction pathways of phytochrome were introduced.

13. Because infrared light can penetrate the skull, it can reach the phytochrome and remotely switch the gene on, resulting in observable changes in the mouse's behavior.

14. They are involved in phototropism, and in PHOTOPERIODISM , where they are thought to affect phytochrome by transferring light energy from blue to red wavelengths.

15. This method should eventually help to identify substances that phytochrome reacts with inside the cell.
