16 p, 1.3 MB A Functional Connection between the Circadian Clock and Hormonal Timing in Arabidopsis / Singh, Manjul (Centre de Recerca en Agrigenòmica) ; Mas, Paloma (Consejo Superior de Investigaciones Científicas)
The rotation of the Earth entails changes in environmental conditions that pervasively influence an organism's physiology and metabolism. An internal cellular mechanism known as the circadian clock acts as an internal timekeeper that is able to perceive the changes in environmental cues to generate 24-h rhythms in synchronization with daily and seasonal fluctuations.

Functional insight on the post-translational modifier SUMO and its biochemical pathway in plants has steadily increased over the past decade. In contrast to the low number of core components that catalytically control SUMO attachment to targets, the enzymes that control deconjugation and SUMO maturation seem to have diversified in terms of both gene number and biological function.
