DNA NICHE OFFERED DIVERGENCE. "Protein and DNA invention were a prerequisite for the evolution of divergence and the variety of life because all evolutionary inventions could be stored as evolutionary protocols in this stable storage medium. The information content of the human genome is comparable to an archive of 5000 books with 300 pages each." https://lnkd.in/euyhznh View in LinkedIn

CLOCK FACTORS. "The nyctinastic leaf movement is induced by a pair of leaf-movement factors, and one of each pair is a glucoside. There are two key proteins that are involved in the control of nyctinasty. One is β-glucosidase: a biological clock regulates the activity of β-glucosidase, which deactivates the glucoside-type leaf-movement factor, controlling the balance in the concentrations of the leaf-closing and -opening factors. The other is the specific receptor for each leaf-movement factor." https://lnkd.in/bF4kXPr View in LinkedIn

DNA AS NEW ECOLOGICAL NICHE. "The high density of early RNA life led to competing situations in which it was an advantage to escape into DNA informational storage and protein-based cellular life." https://lnkd.in/euyhznh View in LinkedIn

OPPOSED ACTIONS. "Based on our experiments on these bioactive substances, we found that the circadian rhythmic leaf movement of these plants is initiated by the regulated balance of LOSs and LCSs. The balance of concentration between the two leaf-movement factors (LMFs) is inversed during the day. The glycoside-type LMF is hydrolyzed with β-glucosidase, the activity of which is regulated by the biological clock. The circadian rhythm observed in the leaf movement is introduced by activation of β-glucosidase regulated by the biological clock." (LOSs = leaf opening substances; LCSs = leaf closing substances). https://lnkd.in/eHVDKsZ View in LinkedIn

RNA VERSUS DNA. "Early RNA-world is plausible because RNA can reproduce itself autocatalytically, which DNA cannot. Moreover, RNA controls the assemblage of amino acids into protein sequences. Some RNAs are as competent as proteins: it can splice itself, i.e. rearrange its own molecular shape anew – it rearranges and reorganizes genetic material." https://lnkd.in/eDswHmC View in LinkedIn

MOLECULAR ACTIVATORS. "The leaves of Mimosa pudica L. are well known for their rapid movement when touched. Recently, we were able to isolate an excitatory substance in small quantities from this plant, which consists of three different components (potassium L-malate, magnesium trans-aconitate, and dimethylammonium salt)." https://lnkd.in/eHVDKsZ View in LinkedIn

CLOCK PIECES. "Up to now, over 20 components related to the circadian clock in Arabidopsis were identified, and homologous genes in other plants have been observed, indicating that this system is highly preserved in plants. The proteins that belong to the circadian clock act at different times during the night and the day, reciprocally regulating the expression of other genes, on the transcriptional and post transcriptional level." http://www.scielo.br/scielo.php?pid=S0100-83582016000100191&script=sci_arttext View in LinkedIn

PHOTORECEPTORS. "The perception of the luminous sign in plants is made by photoreceptors, which include phytochromes (phy), cryptochromes, phototropins, ZTL/ADO family proteins, in addition to a protein family of photoreceptors responsible for absorbing the ultraviolet light (UV-B). Phytochromes are the main photoreceptors, and they are responsible for absorbing the red (R) and far-red (FR) radiation." http://www.scielo.br/scielo.php?pid=S0100-83582016000100191&script=sci_arttext View in LinkedIn

CLOCK DRIVEN. "Approximately 25% of the Arabidopsis genes that encode proteins with several functions are regulated by the circadian clock. Amongst its functions are the regulation of germination, enzymatic activity, stomatal movements and gas exchanges, photosynthesis, flower blossoming and the emission of fragrances." https://lnkd.in/ecWYRcG View in LinkedIn

OSCILLATING GENES. "Circadian factors affect hormone concentrations. For example, cytokinin, auxin, and ABA concentrations show diurnal patterns. TANDEMZINC KNUCKLE/PLU3 (TZP) affects diurnal growth patterns. Its gene expression oscillates, with a peak in the morning. TZP regulates the expression of auxin-related genes." https://lnkd.in/eTEzGE9 View in LinkedIn
