DAYLENGTH SYNCHRONICITY. "Photoperiodic plants are common, even in tropical latitudes where the seasonal daylength changes are small, and daylength is used to synchronize reproductive or other activities with seasonal events such as dry or rainy periods. Coincident flowering in members of a population increases the chances of outbreeding and hence genetic recombination." https://lnkd.in/d_f7kfY View in LinkedIn

RANGE. "The seasonal range and rate of change of daylength is lower in the tropics than at higher latitudes and photoperiodic mechanisms need to be sufficiently precise and flexible to operate across the entire range of daylengths." https://lnkd.in/d_f7kfY View in LinkedIn

SEASONAL CUE. "Photoperiod alone is not an unambiguous signal as any particular daylength occurs twice in an annual cycle. Progressive changes in daylength, which are at their greatest around the equinoxes in spring and autumn, do, however, provide a certain environmental signal for the passage of the seasons." https://lnkd.in/d_f7kfY View in LinkedIn

THE PLANT CLOCK. "In order to locate the time of year accurately, a timekeeping mechanism operates with precision as part of the plant’s photoperiodic sensing mechanism in a way that is insensitive to less predictable variations in the environment such as temperature." https://lnkd.in/d_f7kfY View in LinkedIn

PLANT VASCULAR SYSTEM. "Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants." https://lnkd.in/dAvJk2A View in LinkedIn

FRAGMENT FROM NATURE deals with plants ability to detect photoperiods and circadian clocks that are driven by photoperiods. The ability for clocks to respond to seasons and to day time is critical for the coordination of flowering and reproduction for each plant species; without a coordinated response, reproduction would quickly fail, and all plants in a species must be on the same schedule. The cues and molecular mechanisms for these plant clocks are beginning to be successfully unravelled. View in LinkedIn

VASCULARIZED LEAVES. "When leaves taken from an induced plant are grafted on to a receptor plant, promotion of flowering or other responses occurs only when a graft union has developed." https://lnkd.in/d_f7kfY View in LinkedIn

COMPLEXITY FROM SIMPLICITY. "The Game of Life, created in the 1970s by mathematician John Conway has garnered a cult following. It consists of an infinite grid of square cells that can either be live or dead. It might not sound like much but such humble beginnings can give rise to a zoo of astoundingly complex patterns and processes, which now include self-replicating organisms." https://lnkd.in/d-ckTpQ View in LinkedIn

LEAF GRAFTS. "From grafting experiments, it is known that in some species, induced leaves are independently capable of generating a flowering stimulus over many days or even weeks while in others, favourable cycles must be continued until the apex has become recognizably floral, indicating the need for a continual supply of a floral stimulus (presumably from the leaf) if flower development is to be sustained." https://lnkd.in/d_f7kfY View in LinkedIn

THE GAME OF LIFE was invented by the mathematical genius and rare polymath, John Conway, it became a cult following, and spawned the first code that could create a copy of itself, the replicator. View in LinkedIn
