Photobiology: Plants Respond to LightNo Abstract available for this article.doi:10.1038/222119b0NoneNature Publishing Group UKNature
Light serves as the energy source for plants as well as a signal for growth and development during their whole life cycle. Seedling de-etiolation is the most dramatic manifestation of light-regulated plant development processes, as massive reprogramming of the plant transcriptome occurs at this time...
Calculation of dose-response curves from various experiments.aResponse of plants to light, as observed for a given trait Y, expressed in absolute units. In this case, results of 7 independent experiments with 2–9 light levels are shown. For one of the orange experiments the Y-level at the...
Many plants respond to external light intensity by altering leaf angle. Under low-light conditions, leaves move toward the light source, forming a perpendicular angle to the incident light, which maximizes light energy absorption. Under high-light conditions, plants adjust the position and angle of ...

Plants also respond to light stimuli by the production of secondary metabolites such as phenolics (such as flavonoids). In Silene littorea, variation of flavoinoid production was enregistred in petals, leaves, calyces and stems. Plant exposure to sunlight enhanced the accumulation of anthocyanins ...
They respond when touched by insects and turn toward sources of light. “Plants are not just roboticstimulus-response devices," said Frantisek Balusk a of the University of Bonn in Germany. “They're livingorganisms which have their own problems.Actually making their suffering hearable, however,...

concerning the ways ornamental plants respond to the daily light integral (DLI) at different times of the year in various areas of the country. It notes that increasing the DLI, along with the supplemental lighting can have a strong effect on the time it takes cuttings to roots and plugs ...
Plants are known to respond to odour cues emitted by other plants that may indicate impending environmental stress. These responses are now understood to extend belowground, where root exudates condition rhizosphere soil bacteria communities in ways that enhance future plant growth and defence. ...
