Resumen:
Most organisms adjust their physiology and metabolism in synchronization with the
diurnal and seasonal time by using an endogenous mechanism known as circadian
clock. In plants, light and temperature signals interact with the circadian system to
regulate the circadian rhythmicity of physiological and developmental processes
including flowering time. Recent studies in Arabidopsis thaliana now reveal that the
circadian clock orchestrates not only the expression of protein coding genes but also the
rhythmic oscillation of introns, intergenic regions and non-coding RNAs. Furthermore,
recent evidence showing the existence of different oscillators in separate parts of the
plant have placed the spotlight on the diverse mechanisms and communicating channels
that regulate circadian synchronization in plants.Arabidopsis thaliana now reveal that the
