CONTROL BY INHIBITION. "Other grafting experiments suggested that other substances inhibiting flowering may be involved; the appropriate day-length would then lead to removal of an antiflorigen rather than (or in addition to) synthesis of a floral hormone." https://lnkd.in/d_f7kfY View in LinkedIn

LEAF GRAFT EXPERIMENTS. "It was proposed by Chailakhyan (1936) more than half a century ago that the signal passing between leaves and response sites is a specific flowering hormone: florigen. This idea was based on a series of experiments showing that grafting of leaves from one donor species to a separate receptor species could cause flowering. This strongly suggested the participation of common signals in different species." https://lnkd.in/d_f7kfY View in LinkedIn

FLOWERING SIGNALS. "The role of a florigenic signal has also been confirmed and although its exact nature is still unknown, there are prospects of it being discovered in the foreseeable future. We can also soon expect to understand more fully the basis for the different requirements for light quantity and quality in different species." https://lnkd.in/d_f7kfY View in LinkedIn

"DOWNSTREAM of the clock, expression of the floral regulator CO is rhythmic under diurnal light– dark cycles. Light promotes expression of the CO mRNA at the end of a long day through the action of the rhythmically expressed photoreceptor FKF1. In addition, the circadian oscillator mediates light-independent expression of the CO mRNA at night." https://lnkd.in/d_f7kfY View in LinkedIn

"LIGHT RESETS THE CLOCK through at least two mechanisms, including transcriptional induction of LHY and CCA1 expression and light-induced degradation of the TOC1 protein. Effects of light on the clock are dampened at night through the action of the rhythmically expressed protein ELF3." https://lnkd.in/d_f7kfY View in LinkedIn

ERROR TOLERANCE. "Genes apparently can tolerate a higher percentage of errors than computer code or written text. Sixty-one codons code for only twenty amino acids, so many of the codons are synonymous. Also, proteins can tolerate amino acid substitutions at many positions without losing their function." https://lnkd.in/dH9XaVn View in LinkedIn

COUNTERPARTS. "Digital codes in the form of electronic, magnetic or optical strings of 1's and 0's are as omnipresent in information technology as nucleotide codes in the form of DNA strings of A's, C's, G's and T's are in living nature." http://benthamopen.com/contents/pdf/TOEVOLJ/TOEVOLJ-5-1.pdf View in LinkedIn

SO ENDS this fragment from nature on the light-synchronized control of plant flowering. The ordered universe meshes with life on earth in great clocks with elaborate genetic control to ensure that sperm meets egg at the correct time in the correct place, and that the mandate of life — reproduction — carries on in glorious wasteful abundance to ensure the survival of the species. If ever there was a single metaphoric cartoon of life, then this is it. View in LinkedIn

INEVITABLE. "Computer viruses. Viral evolution may not only be possible but inevitable." https://lnkd.in/g5hUBjg View in LinkedIn

PATHWAY INTERACTIONS. "Floral-promotion pathways do not act in isolation but interact with floral-enabling pathways. The photoperiodic pathway promotes flowering through activation of the floral-integrator genes FT and SOC1, but this is not possible when high levels of FLC are present." https://lnkd.in/d_f7kfY View in LinkedIn
