Aim. A comparative cytological analysis of intra- and intertissue cytomictic interactions in early microsporogenesis of
 mono- and dicotyledonous plants was performed using two cellular systems: microsporocytes and tapetum. Methods.
 Light and fluorescent microscopy. Results.There have been found complex forms of collective «social» cell behavior
 between tapetal cells and microsporocytes. The altruistic behavior prevails among microsporocytes, while competitive
 relationships dominate between microsporocytes and tapetal cells (only monocots). Polyploid tapetum nuclei and
 syncytia as powerful acceptors are able to compete with microsporocytes and guide the chromatin translocation to their
 favor. Conclusions. Intertissue interactions reflect likely the intensification of competition for area in anther between
 the tapetum and microsporocytes. The absence of intertissue interactions in dicots probably reflects a better balance of
 differentiation of anther somatic and generative tissues comparatively to monocots.
