Definition of phytochrome in English:

phytochrome

noun ˈfʌɪtəkrəʊmˈfīdōˌkrōm

mass nounBiochemistry

A blue-green pigment found in many plants, in which it regulates various developmental processes.
〔生化〕植物光敏素，光敏色素
Example sentencesExamples
- The plant photoreceptor phytochrome exhibits remarkable structural and functional variabilities in the plant cell.
- Moreover, it has been suggested that some of the reported blue-UV effects may have resulted from phytochrome instead of blue-UV photoreceptor action.
- Light signalling pathways from both phytochrome and cryptochrome photoreceptors regulate clock components to achieve entrainment in plants.
- This macroscopically observable reaction was identified to be coupled with light-induced processes of the photoreceptor phytochrome.
- This is the opposite of the situation in higher plants, where red light activates and far-red light inactivates phytochrome.

Origin

Late 19th century: from phyto- 'relating to plants' + Greek khrōma 'colour'.
