	       ABSTRACT
	       Plant development is characterized by a continuous
	       growth and flexible adjustments of the plant
	       architecture in response to the environment. Plants are
	       able to maintain permanent stem cell populations,
	       dedifferentiate already committed cells and, not least,
	       to regenerate or form organs de novo. These
	       developmental processes are governed and coordinated by
	       signalling substances called plant hormones. Typically,
	       in certain developmental processes more than one hormone
	       is involved and, thus, coordination of their overlapping
	       activities is crucial for correct plant development.
	       Multiple hormones including cytokinin and auxin have
	       been implicated in the regulation of root development
	       however, molecular mechanisms underlying the hormonal
	       cross-talk are only poorly understood. The main aim of
	       our studies is to reveal the molecular components and
	       mechanisms balancing the output of auxin and cytokinin
	       pathways in order to regulate plant organogenesis. We
	       use lateral root organogenesis in Arabidopsis as an
	       ideally suited model system for these questions, because
	       it encompasses fundamental aspects of plant development,
	       such as dedifferentiation, re-entry into the cell cycle,
	       coordinated cell divisions and differentiation, and is
	       in antagonistic manner regulated by  auxin and
	       cytokinin. Recent insights into mechanisms of auxin and
	       cytokinin cross-talk during lateral root organogenesis
	       will be discussed.
