Gravity and developmental plasticity.
Abstract
Living organisms, especially plants, show some plasticity in their overall development, usually as a response to the external environment. Plasticity may apply not only to the external form of organisms but also to their physiology as well as to the detailed structure of their genome. A further example of plasticity may be developmental instability, where anomalous development seems to appear spontaneously, probably as a result of some transient environmental perturbation. Whether the absence of gravity would have sufficient impact on any living process to evoke a specific course of plastic development is unknown, though it is possible that in certain circumstances special forms, or 'agravimorphs', could be produced. Through such new forms, it should be possible to identify processes required for development in which 1 x g gravity is a necessary participant.
