  abstract = {Tabony and co-workers [C. Papaseit, N. Pochon, and J. Tabony, Proc.
	Natl. Acad. Sci. U.S.A. 97, 8364 (2000)] showed that the self-organization
	of microtubules from purified tubulin solutions is sensitive to gravitational
	conditions. In this paper, we propose two models of spatial and orientational
	self-organization of microtubules in a gravitational field. First,
	the spatial model is based on the dominant chemical kinetics. The
	pattern formation of microtubule concentration is obtained (1) in
	terms of a moving kink in the limit when the disassembly rate is
	negligible, and (2) for the case of no free tubulin and only assembled
	microtubules present. Second, the orientational pattern of striped
	microtubule domains is consistent with predictions from a phenomenological
	Landau-Ginzburg free energy expansion in terms of an orientational
	order parameter.},
