BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Phytochromes directly perceive ambient light as well as temperature information. Through co-ordination between photoreceptors, they can modulate myriad of plants’ responses including biotic and abiotic stress responses, gravitropism, as well as multiple developmental transitions.

Detailed explanation-2: -Phytochromes are red (R)/far-red (FR) light photoreceptors that play fundamental roles in photoperception of the light environment and the subsequent adaptation of plant growth and development.

Detailed explanation-3: -A key role of phytochromes in natural light environments involves the monitoring of daylength or photoperiod which, together with temperature, provide plants with important seasonal information.

Detailed explanation-4: -Phytochromes are a class of photoreceptor in plants, bacteria and fungi used to detect light. They are sensitive to light in the red and far-red region of the visible spectrum and can be classed as either Type I, which are activated by far-red light, or Type II that are activated by red light.

Detailed explanation-5: -It is widely believed that upon absorbing red light, phytochrome induces plant light responses by regulating the transcription of numerous target genes. In this study, we provide clear evidence that phytochrome controls not only transcription, but also alternative splicing in Arabidopsis.
