text: 'Plants are sessile organisms that are permanently restricted to their site
of germination. To compensate for their lack of mobility, plants evolved unique
mechanisms enabling them to rapidly react to ever changing environmental conditions
and flexibly adapt their postembryonic developmental program. A prominent demonstration
of this developmental plasticity is their ability to bend organs in order to reach
the position most optimal for growth and utilization of light, nutrients, and
other resources. Shortly after germination, dicotyledonous seedlings form a bended
structure, the so-called apical hook, to protect the delicate shoot meristem and
cotyledons from damage when penetrating through the soil. Upon perception of a
light stimulus, the apical hook rapidly opens and the photomorphogenic developmental
program is activated. After germination, plant organs are able to align their
growth with the light source and adopt the most favorable orientation through
bending, in a process named phototropism. On the other hand, when roots and shoots
are diverted from their upright orientation, they immediately detect a change
in the gravity vector and bend to maintain a vertical growth direction. Noteworthy,
despite the diversity of external stimuli perceived by different plant organs,
all plant tropic movements share a common mechanistic basis: differential cell
growth. In our review, we will discuss the molecular principles underlying various
tropic responses with the focus on mechanisms mediating the perception of external
signals, transduction cascades and downstream responses that regulate differential
cell growth and consequently, organ bending. In particular, we highlight common
and specific features of regulatory pathways in control of the bending of organs
and a role for the plant hormone auxin as a key regulatory component.'
