Title: Memory and Learning in Seeds, Plants, Flowers, and Fruits: Memristors

Principal Investigator: Dr. Alexandre George Volkov

Abstract

Plants have different forms of memory, such as sensory, short, and long-term memory. Memory is the ability to store the state of a system at a given time and access this information at a later time. Possible candidates for memory in seeds, plants, flowers, and fruits are memristors, which are resistors with memory. Memristors are memory circuit elements whose properties depend on the history and state of the system. Memristors can participate in electrical signal transduction between phytosensors and phytoactuators. Recently, memristors were found as components of plasma membranes in many plants, flowers, fruits and seeds. The analysis of presence of memristors in a bio-tissue is based on cyclic voltammetric characteristics where the memristor, a resistor with memory, should manifest itself. The discovery of memristors in the plant kingdom creates a new direction in the modeling and understanding of electrical phenomena in plant membrane structures. It can be a starting point for understanding mechanisms of memory, learning, circadian rhythms and biological clocks. The conduction of electrochemical signals must be regarded as one of the most universal properties of living organisms. It arose in connection with a need for the transmission of a signal about an external influence from one part of a biological system to another. The study of the nature of regulatory relations of the plant organism with the environment is a basic bioelectrochemical problem. Ion transport is essential to the generation of membrane potentials, signal transduction, and other biological processes. Ion channels are nanodevices in the engineering sense: they have signal inputs, power supplies, and signal outputs. Voltage gated K+-channels, which have memristive properties, play important role in circadian rhythms. It is more probable that plant memory and electrical properties of circadian rhythms depend on memristors and memcapacitors. Plants have biological clocks and circadian rhythms, which involve electrical elements of memory. Many plants are able to memorize daytime and nighttime. The biological clock in plants is sensitive to light and reducing chemicals, which can reset the phase of the rhythm.
