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 ...
Response of the Living and Non-Living’ published in 1902, revealed that every plant and every plant organ is excitable and responds to stimulus by electric response. [3] Furthermore, ‘Plant Response as a means of physiological investigation’ published in 1906, proved, through the use of a method of mechanical response, that the conduction ...
Once the plant perceives a mechanical stimulus via mechanoreceptor cells or mechanoreceptor proteins within the plasma membrane of a cell, the resulting ion flux is integrated through signaling pathways resulting in a response. The signaling cascade (integration) and response is dependent on the type of stimulus and the particular species.
In general, cellular response to stimuli is defined as a change in state or activity of a cell in terms of movement, secretion, enzyme production, or gene expression. [9] Receptors on cell surfaces are sensing components that monitor stimuli and respond to changes in the environment by relaying the signal to a control center for further ...
The third aspect of plant memory is epigenetics, where the plant, in response to a stimulus, undergoes histone and chromatin modification leading to changes in gene expression. These changes lead to a subsequent change in what proteins are made by the plant and establish a way for the plant to respond or be affected by stimuli from past ...
In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi. This behavior occurs due to unilateral growth inhibition. [1]
The integration of the stimuli in plant cells is not fully understood, but the movement of the cell nucleus provides one example of a cellular process that underlies plant behavior, and highlights the importance of the cytoskeleton in solving spatial problems within the plant cell.
Upon stressful events, there is variation in a plant's response. That is to say, it is not always the case that a plant responds with an action potential or variation potential. [42] However, when a plant does generate either an action potential or variation potential, one of the direct effects can be an upregulation of a certain gene's ...
