SIGNAL STORAGE. "A more complex form of memory requires information storage of previous signalling, with the ability to retrieve the information at a much later time. Both forms occur in plants." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

ACTIONABLE ACCESS. "All these forms of memory can be recognized by the ability to interact with, and modify, the transduction pathways to new signals. The only requirement is merely that the memory can be accessed and can influence the response to the current signal." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

CALCIUM. "It is also clear that the history of stimulation modifies subsequent transduction and, in plants, intepretation through [Ca2+] is likewise modified by previous signalling, ensuring another form of memory is present." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

TYPES OF MEMORY. "There are different types of memory, among which are priming memory, store/recall memory (STO/RCL), where both the storage and the recall function as well as their combination have ecophysiological significance, and epigenetic memory. Timing is important. Therefore, ultradian, circadian and annual rhythms are underlying memory functions, where the circadian clock may represent a prominent component." http://link.springer.com/chapter/10.1007/978-3-319-25688-7_2 View in LinkedIn

SINGLE TRIGGER. "Memory of developmental status. The effects of blue or red light signals are good examples, having different effects dependent on the stage of development. Thus, red light can affect leaf movement, stem elongation or germination." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

TENDRIL MEMORY. "In this case the mechanical stimulation is remembered for several hours and is a meaningful memory in terms of the response of the tendril that also takes several hours to coil. Plant memory can last seconds, minutes, days, weeks and months according to the time frame of the signal and the developmental response examined." http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

DURATION OF MEMORY. "A number of plant developmental changes require two signals for completion. By giving one signal without the other, the length of time the memory of that one signal lasts, can be easily established. Thus, for example tendrils require both a mechanical stimulus and blue light to coil. By separating the time of application of the two signals the length of the memory of one signal can be determined.' http://link.springer.com/article/10.1007/s00114-005-0014-9 View in LinkedIn

LEARNING. "There can be no doubt that the developmental history of a plant can determine the outcome of many subsequent sensing events. More accurately, the developmental history of many organs (or cells) can determine the response that results from subsequent stimulation." http://aob.oxfordjournals.org/content/93/4/345.full View in LinkedIn
