The nervous system controls conscious and unconscious motor and sensory as well as emotional and intellectual functions. It is divided in the central nervous system (CNS) and the peripheral nervous system (PNS) (Figure 13.1). The CNS consists of the brain and spinal cord.
1 sie 2006 · Despite the repeated demonstrations of electrical long-distance signals in plants, the concept of a plant nervous-analog system lost popularity in the scientific community in favor of a chemical diffusion mechanism of signaling coinciding with the discovery and effects of plant hormones.
8 sty 2020 · By approaching the study of plant signaling and behavior in information-processing terms, and not simply in terms of the underlying physiology, we may generate a number of predictions at the levels of: (i) plant anatomy and connectivity, and (ii) electrophysiology.
12 cze 2021 · The plant nervous system is fundamentally dedicated to transmitting information, and it carries out a low level of information processing, even in carnivorous plants (e.g., the Venus flytrap) – this is true even if plants can process information in the root apex transition zone.
6 maj 2020 · The present review focuses on the recent developments of various NTs signaling mechanisms in plants. Moreover, it summarizes the role of NTs in plant growth and development, stress tolerance and ecophysiological behaviors. Table 1. Effects of melatonin and serotonin on plant growth and development.
Among the metabolic neurotransmitters, acetylcholine, catecholamines, histamines, serotonin, dopamine, melatonin, GABA (γ-aminobutyric acid) and glutamate are the most common in the animal nervous system, playing roles in sensing, locomotion, vision, information processing and development.
A big challenge facing plant neurobiologists is connecting this molecular information obtained at the cellular level to understanding long-dis-tance electrical signaling and systemic responses in plants. Plants can propagate two principal types of electrical signals (Box 2).
