RNA DRIVEN. "It appears that all the detailed steps of evolution stored in DNA that are read, transcribed, and translated in every developmental and growth process of each individual cell depend on RNA-mediated processes, in most cases interconnected with other RNAs and their associated protein complexes and functions in a strict hierarchy of temporal and spatial steps." https://lnkd.in/euyhznh View in LinkedIn

CIRCADIAN MOVEMENT. Tribulus cistoides. "Its bright yellow flowers come to life at sunrise and face into the sun. During the day, as the sun appears to move across the sky, the flowers of Tribulus track the sun like little satellite dishes, reorienting themselves so that they always face into the sun. When the sun drops below the horizon, the flowers close. Some species of day-flowering plants can open and close their flowers for several days in succession." https://lnkd.in/bgcAj66 View in LinkedIn

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
