DATA RECALL AND EVALUATION. "Developmental decisions, such as vernalization, flowering induction, photomorphogenesis or breaking of seed dormancy depend on long-term integration and evaluation of light or temperature inputs, sometimes recorded and recalled after a time far exceeding the normal duration of the plant's life cycle." https://lnkd.in/dfsCv77 View in LinkedIn

WHOLE PLANT MEMORY. "But can it be found also on the whole plant level? One promising example is the developmental memory represented by reaction of axillar buds of Scrophularia cuttings to leaf removal, demonstrated by classical experiments of R. Dostál from the 1960s, or later experiments demonstrating specific response of Bidens axillar buds to cotyledon injury in decapitated plants. later experiments demonstrating specific response of Bidens axillar buds to cotyledon injury in decapitated plants.” http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn

MEMORY CANDIDATE. "One promising candidate, as long as we attribute individuality also to cells, would be auxin canalization, i.e., gradual tuning of auxin transport across cells and tissues, based on their previous experience and resulting in increased auxin flow in cells that already have transported auxin. This phenomenon, which has been proposed as a major factor determining e.g., the topology of leaf venation." http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn

PRESENT AND FUTURE ASSESSMENT. "Thus, at each setting of the environment, the individual plant can access information that it can use to construct a response and to ensure that overall, maximal fitness will be achieved. The implication is that the difference between the optimal niche/phenotype and the present environment and present phenotype can be measured." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

NEIGHBOR EFFECTS. "The response of an individual along a resource gradient is very strongly influenced by its neighbours. While negative interactions through competition for the basic resources of space, light, minerals and water, and interactions through allelopathy, are well established." (Allelopathy is the production of chemicals to influence the growth of nearby plants.) http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

VAST DATA INPUT. "If there are about 15 environmental factors acting in differing degrees and affecting the perception of each other then the combination of possible environments in which any individual can find itself and to which it must respond is enormous. Thus, the necessity for learning rather than rote behaviour. Moreover, long‐ and short‐term responses to environmental variables will be different." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

PLASTICITY AND FITNESS. "Individual plants that express plasticity will more nearly approach the fitness objective than individuals that do not. But the error‐correcting mechanism must involve complex negative feedback mechanisms with versions of trial and error; that is, learning." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

ANTICIPATED NEED. "Most interestingly, starch mobilization at the night is essentially linear, resulting in nearly complete consumption of the starch reserve during every night. Thus, the plant is apparently able to measure the amount of starch at the end of the day and “anticipate” the length of night." http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn
