Details: " Auxin - cytokinin interaction shaping root
architecture"
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.
