	       ABSTRACT
	       In plant cells, the set up of the various microtubule
	       arrays that follow one another during the cell cycle
	       (cortical interphase array, preprophase band, spindle,
	       phragmoplast) is obviously intimately connected with the
	       cell cycle machinery. However, the activities and
	       signals that coordinate and regulate the transitions of
	       the microtubule cytoskeleton are mostly unknown.
	       Our recent results have revealed a large regulatory
	       complex (TTP) composed of at least 5 protein partners.
	       The recruitment of the TTP complex to the cytoskeleton,
	       and its activity at the G2/M transition are necessary
	       for division plane determination and PPB formation in
	       Arabidopsis and moss. This complex also plays a pivotal
	       role in the organization of the interphase array during
	       diffuse growth. Interestingly enough, most proteins
	       involved in the TTP complex have similarities with
	       proteins involved in the centrosome of animal cells,
	       providing the first evidence of an evolutionary link
	       between the animal centrosome and the cortical
	       cytoskeleton of acentrosomal plant cells.
