Description

As the agency reported it.

Characterizing plant gravity perception systems plant growith is characterized by plasticity, allowing environmental cues like light and gravity to play a significant role in determining the overall form of the plant body. Statolith sedimentation in specialized cells represents one way that plants percieve gravity. Plants lacking functional statolith show reduced but consistent gravity responses, suggesting the presence of a non-statolith sensory system. This proposal seeks to investigate the gravity perception machinery in roots of several genotypes of the higher plant arabidopsis thaliana by taking advantage of the unique microgravity ENVIRON1NENT of earth orbit on the LSS. One thrust of the work described here is to characterize the physiological properties of the putative non-statolith sensory system, including the threshold acceleration force required to activate IT, and its capacity to modulate downstream growth regulation machinery. The second thrust is to deremine whether the two gravity sensory systems control a single or multiple output systems. Addressing this question requires the microgravity environment in order to quantify the kinetics of gravitropism in roots having or lacking functional statolith under fractional g conditions. The overall outcome of the work proposed here will be an improved understanding of how higher plants perceive gravity and transduce this physical CUE into directional growth, a fundamental requirement for improving plants for production on earth and in long-term spaceflight missions.
