Auxins (plural of auxin / ˈ ɔː k s ɪ n /) are a class of plant hormones (or plant-growth regulators) with some morphogen-like characteristics.Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development.
Plant (control theory) A plant in control theory is the combination of process and actuator. A plant is often referred to with a transfer function (commonly in the s-domain) which indicates the relation between an input signal and the output signal of a system without feedback, commonly determined by physical properties of the system. An ...
Book cover. “The Nervous Mechanism of Plants”, published in 1926, is a botany book by Sir Jagadish Chandra Bose which summarises his most recent findings in the area of plant physiology. Bose had previously investigated this topic in books such as Plant response as a means of physiological investigation from 1906, or The physiology of ...
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Plant hormone. Lack of the plant hormone auxin can cause abnormal growth (right) Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, [ 1 ] the regulation of organ size, pathogen ...
Plant communication. Plants are exposed to many stress factors such as disease, temperature changes, herbivory, injury and more. [1] Therefore, in order to respond or be ready for any kind of physiological state, they need to develop some sort of system for their survival in the moment and/or for the future.
Plant pathogens tend to spread via spores or are carried by animal vectors. One of the most important advances in the control of plant disease was the discovery of Bordeaux mixture in the nineteenth century. The mixture is the first known fungicide and is a combination of copper sulfate and lime.
Plant cognition. Plant cognition or plant gnosophysiology[1] is the study of the learning and memory of plants, exploring the idea it is not only animals that are capable of detecting, responding to and learning from internal and external stimuli in order to choose and make decisions that are most appropriate to ensure survival.
