The developing cotton fiber is considered as a model system for studying the function of microtubules in plant cell elongation and cell wall biosynthesis. It has been shown that microtubules undergo active dynamic changes during fiber development. At the molecular level, Dixon et al demonstrated that two alphatubulin and two beta-tubulin isoforms accumulated preferentially in fibers, and Whittaker and Triplett showed that the accumulation of alpha-tubulin transcripts changed in a gene-specific manner in the developing cotton fibers.

In plants, several cellular processes like celldivision, differentiation, polar growth, and response to pathogen attack depend on rapid reorganization of the actin cytoskeleton. The reconstruction of actin filaments is controlled by a wide variety of actin-binding proteins, of which, profilin is one of the key modulators.

Its kink and anti-kink solutions are presented explicitly. In particular, some exact multi-kink and anti-kink wave solutions are discussed and under some conditions, the kink and anti-kinks look like hat-shape solitons. The dynamic characters of the obtained solutions are investigated by figures. The method used in this paper can be widely applied to looking for the multi-kinks for Camassa–Holm type equations possessing cubic nonlinearity.展开更多
