WebSep 1, 2005 · Circadian clocks are cellular oscillators that organize temporal expression of large numbers of genes in many organisms. They are synchronized to the 24-h cycle of earth rotation, and changes in light and ambient temperature are major natural cues (zeitgebers) for entrainment.Without zeitgebers, circadian clocks oscillate with their endogenous free … Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods. They are classified under three groups according to the photoperiods: short-day plants, long-day plants, and day-neutral plants.
WebPlant cells have sites dedicated to both respiration and photosynthesis. The mitochondria are for respiration, while the chloroplast are for photosynthesis. Both processes produce the materials needed for the other to function.

We create a real-time photoperiod reporter, using the PP2-A13 promoter driving luciferase, and show that photoperiodic regulation is independent of the canonical CO/FT mechanism for photoperiodic flowering.
