WAVING AND COILING OF ARABIDOPSIS ROOTS AT DIFFERENT G-LEVELS (WAICO AND WAICO-
2), TWO INVESTIGATIONS
Research Area: Plant Biology
Expedition(s): 16
Principal Investigator(s): ● Günter Scherer, PhD, Leibniz Universitat Hannover,
Hannover, Germany
RESEARCH OBJECTIVES
Waving and Coiling of
Arabidopsis Roots at Different
g-levels (WAICO) has been
studying the interaction of
circumnutation (the successive
bowing or bending in different
directions of the growing tip of
the stems and roots) and
gravitropism (a tendency to
grow toward or away from
gravity) in microgravity and 1 g
of Arabidopsis thaliana
(commonly known as thale
cress). One aim specifically is to
verify that circumnutation of
Arabidoposis roots is driven by an endogenous mechanism that is independent of gravity as a
cue.
RESULTS
Postflight analysis is complete, and publication of results is imminent.
This investigation is complete; however additional results are pending publication.
