Possible effects of organelle charge and density on cell metabolism
Abstract
To respond to gravity a biological system must: First, perceive the stimulus; and, second transduce the stimulus into an appropriate response. This laboratory has studied a system of perception and transduction involving the gravity-induced asymmetric distribution of a plant growth hormone. From these studies we have developed a working theory which states as its postulates that: a) The perception of the gravitational stimulus involved a perturbation of the plant's bio-electric field; and b) that the transduction of the stimulus involved voltage-gating of hormone movement from the plant's vascular tissue into the hormone responsive growing tissue. These studies may provide the simplest system for studing the mechanism whereby the gravity signal is translated into a biological response.
