Circadian rhythms in Lhc gene expression in pharbitis nil chois
… oscillator from those which govern the photoperiodic response rhythm or leaf movement rhythm in P. nil. These results indicate that the Lhc rhythm may, however, share a common underlying oscillator with the transpiration rhythm in P. nil.

Juvenility in three composite genera with ornamental potential: Rudbeckia, Gaillardia and Solidago
… flexicaulis exhibited a complex (combination) photoperiodic response, requiring an extended LO exposure prior to SO initiation. The last treatment, consisting of 12-week-old-plants transferred from LO to SO, flowered most rapidly in 62 days. Other measured characteristics such as stem length, …

The effect of photoperiod on central steroid receptor expression and plasma hormone concentration in the ring dove (Streptopelia Risoria)
… of this study are consistent with an inhibitory photoperiodic response acting upon the anterior pituitary gland and the four hypothalamic brain regions involved in the ring dove breeding cycle.

Studies of in vitro flowering and de novo flowers of Nicotiana tabacum
… of floral promoters and inhibitors. TCLs from photoperiodic species of tobacco did not form flowers de novo , whereas TCLs from day-neutral plants did flower. When TCLs were removed from photoperiodic plants and grafted in vitro to TCLs from day-neutral plants, there was no indication that a …

Flowering Gene Homologs Regulate Seasonal Growth Changes in Poplar
The adaptation of trees to temperate and boreal climates depends on their ability to respond to environmental signals that are markers of seasonal changes in order to survive winter and maximize growth. The genus Populus (poplars) is a model system for identifying the genes and molecular mechanisms …
