Characterization of GhRac1 GTPase expressed in developing cotton (Gossypium hirsutum L.) fibers.

Abstract

Cytoskeleton assembly plays an important role in determining cotton fiber cell length and morphology and is developmentally regulated. As in other plant cells, it is not clear how cytoskeletal assembly in fibers is regulated. Recently, several Rac/Rop GTPases in Arabidopsis were shown to regulate isotropic and polar cell growth of root hairs and pollen… (More)
