Summary— Microtubule‐associated proteins (MAPs) are one of the factors which regulate the different properties of microtubules during cell cycle and differentiation. They have been characterized as proteins which promote tubulin assembly in a concentration‐dependent manner and bind to the outer surface of the polymers in vitro . Most of our knowledge comes from studies of neural microtubule‐associated proteins and recent results highlight their implication in neuronal morphogenesis. In contrast, until recently, few data are available about the proteins that associate with plant tubulins. This is due principally to the fact that plant microtubule‐associated proteins cannot be purified by the standard procedures used for neural microtubule‐associated proteins. First, we will describe methods which have been used to isolate these proteins in plant cells. We will then discuss the biochemical and immunological properties of the plant microtubule‐associated proteins which have been isolated. From these results, putative functions can be proposed for these proteins n the particular plant cytoskeleton activities.
