SO ENDS this string on the political squashing of astrobiology. The question of whether we are alone in the universe is one of the most important open questions today. Imagine waking tomorrow to news that the Little Green Men had landed on Earth. The recent UFO footage release by the Pentagon of footage taken by US Navy pilots has sparked a mainstream resurgence in the topic. Its suppression for so long smells like clumsy governments sitting on certain knowledge that it deems will panic the stupid populous. https://lnkd.in/dpXfjhZ View in LinkedIn

LIVING GYROSCOPE. “Interactions between circadian clocks and photosynthesis for the temporal and spatial coordination of metabolism. A number of recent studies have demonstrated that the circadian clock is integrated very closely with photosynthesis and its metabolic products. We describe how this might provide adaptations to optimize plant performance in an environment that varies both predictably upon a daily and seasonal basis, and unpredictably due to the weather.” https://lnkd.in/dwMRFri View in LinkedIn

STILL UNRESOLVED. “Although endogenous control of rhythmic growth was described in oaks more than a century ago, the mechanisms involved have not yet been elucidated.” http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

NEW PERSPECTIVE. “Interactions with mycorrhizal fungi should be considered in studies on the rhythmic growth of trees, because this ecologically obligatory symbiosis of roots not only enhances the acquisition of soil nutrients and stimulates photosynthesis of trees, but also changes their allocation among plant parts.” http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

RHYTHMIC GROWTH IN TREES. “The growth of many trees is not continuous, but is interrupted by episodic rest phases. Pedunculate oak (Quercus robur L.), a major forest tree species in European forests, displays rhythmic growth with successive growth/rest phases of fixed periods of 18–22 d under constant culture conditions, which reflects the endogenic character of this trait." http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

INTERNAL CLOCK OF TREES. "Endogenous rhythmic growth in oak trees is regulated by internal clocks rather than resource availability. The results indicate that rhythmic growth involves dramatic oscillations in plant metabolism and gene regulation between below- and above-ground parts. Ectomycorrhizal symbiosis may play a previously unsuspected role in smoothing these oscillations without modifying the rhythmic growth pattern." https://lnkd.in/ds4PhA9 View in LinkedIn

CONTROL LOOPS. “The clock appears thus far to be considerably conserved with the rest of the plant kingdom. Thanks to molecular studies, and the use of circadian reporter systems, we know that the central oscillator consists of three interlocking auto-regulatory transcriptional feedback loops.” https://lnkd.in/dyrdvNg View in LinkedIn
