Photoreceptor is the key for plants to perceive changes in the external environment. In the light reaction of plants, the most important photoreceptor is phytochrome, which absorbs red light and far-red light. phytochrome is a kind of pigment protein that have a reversal effect on the absorption...
Small RNAs are also an essential factor in plants where they play a role in regulating the activation of functional genes and transposons [3]. The results of our analysis show that R/FR conditions have a large effect on gene expression levels in agarwood. RNA-seq data revealed an array of...
When 5 minutes of red light were given in the middle of the 16-hour dark period to which whole plants were exposed daily for 14 days before making cuttings, the percentage of tuberization on cuttings decreased. The effect of red light was significantly reversed by 2 minutes of far-red ...
plants get from their photoreceptors sometimes cause significant reactions.And many plants are seasonal.And one way they know when winter is ending and spring is beginning is by sensing the change in light.The time when an adult plant flowers is based on the amount of light the plant senses....
(ii) Does the absence of far-red have any negative effects on plants grown in LED systems? To answer these questions, it is important to mention the physiological roles of far-red light. In general, this part of the nonvisible spectra has two major roles: photoreceptor-mediated environmental...
To investigate the effects of red light and blue light on leaf senescence and active oxygen metabolism,the two grape variety Vitis vinifera'Italia'and V. vinifera'Centenial Seedless' with different senescence-types cultured in protected and delayed cultivation were studied.'Italia'and'Centenial Seedless...
There was no significant effect of treatments on time to first flower in Impatiens. However, Petunia plants under low PAR transmission films took longer to flower. Plastic films which filter out FR light to increase the R:FR ratio, combined with high PAR transmission, can therefore be used as...
synthesis of anthocyanins55,56. The joint cross-response of multiple environmental factors is the general trend of future research on plant growth and development and quality formation. Light and temperature often act on plants together, and PIF4, as an important transcription factor of light and ...
