Plant growth strategies are remodeled by spaceflight

Abstract: BackgroundArabidopsis plants were grown on the International Space Station within specialized hardware that combined a plant growth habitat with a camera system that can capture images at regular intervals of growth. The Imaging hardware delivers telemetric data from the ISS, specifically images received in real-time from experiments on orbit, providing science without sample return. Comparable Ground Controls were grown in a sister unit that is maintained in the Orbital Environment Simulator at Kennedy Space … Show more

“…However, roots that are agravitropic due to defects in auxin signaling or transport, or due to removal of gravity-sensing tissues, still form LRs on the outside of curves, suggesting that the gravity response is not specifically required (Ditengou et al, 2008;Lucas et al, 2008;Richter et al, 2009). Recent observations of roots grown during spaceflight further indicate that the pattern of LRs and gravitropic responses of the primary root are separable; in the micro-g environment, roots grow more slowly than those of control plants on Earth (at 1 g), but root waving persists and LRs are observed on the outside of curves (Paul et al, 2012). Thus, root waving and the coincidence of LRP with curves occur independently of gravity.…”

“…S4). Long-term (hours to days) morphological responses of plants under hypergravity or mg conditions have been described using plants grown in a centrifuge (Fitzelle and Kiss, 2001;Matsumoto et al, 2010) or aboard the space shuttle/station (Kiss et al, 1999(Kiss et al, , 2012Paul et al, 2012;Roux, 2012), respectively. Such reports indicate that plants can respond with alterations in growth and development to a variety of gravitational accelerations.…”

“…Systems have been incorporated into both temporarily and permanently installed ISS plant growth hardware such as Advanced Astroculture (Link et al, 2003;Zhou, 2005), Biomass Production System (BPS) (Morrow and Crabb, 2000;Stutte et al, 2005), Plant Generic Bioprocessing Apparatus (PGBA) (Hoehn et al, 1996;Evans et al, 2009), Lada (Sychev et al, 2007;Bingham et al, 2003), European Modular Cultivation System (EMCS) (Brinckmann, 2005;Johnsson et al, 2009), Biolab (Brinckmann, 2005) and the Green Fluorescent Protein (GFP) Imaging System (GIS) within the Advanced Biological Research System (ABRS) (Paul et al, 2012;Levine et al, 2009). Visible light imaging has been implemented in the bulk of these plant growth chambers, but monitoring has also been conducted through infrared and fluorescent means.…”
