Perception of gravity by plants.
Physical principles can be used to predict some features about the gravity perception system in plants. The nature of the system has made it rather elusive, so this approach represents an additional source of information to help find it. For a gravitational stimulus to be detected, two masses must move relative to each other in a manner which causes a significant amount of work to be done on ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
A Unified Model of Shoot Tropism in plants: Photo-, Gravi- and Propio-Ception — Supplementary Material
where s is the curvilinear abscissa along the organ, from the base s = 0 to the tip of the organ s = L and t is the time. νA(L, t) is the apical photoceptive term, readily transmitted all along the organ, and γC(s, t) is the proprioceptive term. Let now the initial conditions be a straight but tilted organ and the boundary conditions of a basal perfect clamping, : A(s, 0) = A(0, t) = A0 C(s, 0)...
متن کاملA Unified Model of Shoot Tropism in Plants: Photo-, Gravi- and Propio-ception
Land plants rely mainly on gravitropism and phototropism to control their posture and spatial orientation. In natural conditions, these two major tropisms act concurrently to create a photogravitropic equilibrium in the responsive organ. Recently, a parsimonious model was developed that accurately predicted the complete gravitropic and proprioceptive control over the movement of different organ...
متن کاملGravity Research on Plants: Use of Single-Cell Experimental Models
Future space missions and implementation of permanent bases on Moon and Mars will greatly depend on the availability of ambient air and sustainable food supply. Therefore, understanding the effects of altered gravity conditions on plant metabolism and growth is vital for space missions and extra-terrestrial human existence. In this mini-review we summarize how plant cells are thought to perceiv...
