GENE OSCILLATORS. “Higher plant circadian rhythms arise from a gene network termed the circadian oscillator. This incorporates autoregulatory and interlocked transcription-translation feedback loops. The nature and interconnectivity of the network produces under constant environmental conditions 24 h cycles of transcription of genes encoding oscillator components.” https://lnkd.in/dAX4kdh View in LinkedIn

MAJOR REGULATOR. “In the model plant Arabidopsis thaliana, biomass accumulation, photosynthesis, seed number and seed viability are increased by correct circadian regulation.” https://lnkd.in/dUkZXhu View in LinkedIn

CIRCADIAN PHOTOSYNTHESIS. “A number of recent studies have demonstrated that the circadian clock is integrated very closely with photosynthesis and its metabolic products. We consider the coupling of the circadian oscillator with carbohydrate biochemistry and the connections between the nuclear-encoded circadian clock and processes within chloroplasts.” https://lnkd.in/dwMRFri View in LinkedIn

PLANT COMMUNICATION is a subject I have delved into a few times already in this blog, including volatile organics such as jasmonate, root exudates, and the mycorrhizal infrastructure connecting plant roots. This section continues that thread in a bit more detail. View in LinkedIn

TIME ZONES. “Plant circadian oscillators may be coupled between organs. Circadian rhythms occur in roots that are isolated from light.” https://lnkd.in/dAX4kdh View in LinkedIn

COORDINATED OSCILLATORS. “Around 70% of chloroplast transcripts can be circadian regulated. In plants, until recently the prevailing view was that circadian oscillators are locally-autonomous with a degree of cell type specialization. However, recent advances demonstrate that interactions occur between the circadian clocks of cells of individual tissues, different tissues, and different organs.” https://lnkd.in/dAX4kdh View in LinkedIn
