“…Although lack of gravity was shown to affect cell wall composition, xylem development, cell shape, cytoskeleton, cell proliferation and leaf morphology (Hoson et al 2003(Hoson et al , 2004Stutte et al 2005Stutte et al , 2006Sieberer et al 2009;Mat ıa et al 2010), the early reproductive development occurs quite normally. Despite indications for some considerable microgravity-specific changes, such as reduced cell cycle, enhanced proliferation rates, gene expression changes and many more (see also De Micco et al 2014a;Herranz & Medina 2014;Hoson et al 2014;Kiss 2014;Kordyum 2014), it is possible to grow healthy plants from seeds and produce viable seeds in optimised growth chambers in orbit, a result judged as a major milestone some years ago, especially in the context of BLSS.

Gravity has shaped the evolution of life since its origin. However, experiments in the absence of this overriding force, necessary to precisely analyse its role, e.g. for growth, development, and orientation of plants and single cells, only became possible with the advent of spaceflight. Consequently, this research has been supported especially by space agencies around the world for decades, mainly for two reasons: first, to enable fundamental research on gravity perception and transduction during growth and development of plants; and second, to successfully grow plants under microgravity conditions with the goal of establishing a bioregenerative life support system providing oxygen and food for astronauts in long-term exploratory missions. For the second time, the International Space Life Sciences Working Group (ISLSWG), comprised of space agencies with substantial life sciences programmes in the world, organised a workshop on plant biology research in space. The present contribution summarises the outcome of this workshop. In the first part, an analysis is undertaken, if and how the recommendations of the first workshop held in Bad Honnef, Germany, in 1996 have been implemented. A chapter summarising major scientific breakthroughs obtained in the last 15 years from plant research in space concludes this first part. In the second part, recommendations for future research in plant biology in space are put together that have been elaborated in the various discussion sessions during the workshop, as well as provided in written statements from the session chairs. The present paper clearly shows that plant biology in space has contributed significantly to progress in plant gravity perception, transduction and responses - processes also relevant for general plant biology, including agricultural aspects. In addition, the interplay between light and gravity effects has increasingly received attention. It also became evident that plants will play a major role as components of bioregenerative life support and energy systems that are necessary to complement physico-chemical systems in upcoming long-term exploratory missions. In order to achieve major progress in the future, however, standardised experimental conditions and more advanced analytical tools, such as state-of-the-art onboard analysis, are required.

“…Kordyum () provides a short overview on the effects of real and simulated microgravity on cell components, including statolith positioning, mitochondria, tubulin and the endoplasmic reticulum. Although significant progress has been made in identifying stimulus‐responsive elements, the nature of the sensors remains elusive.…”

Palme, K.Wiley-blackwellHoboken1Si[début du texte]In August 2012, more than 60 invited scientists and representatives of space agencies from different continents, nationalitiesand disciplines attended the international workshop on ‘Plant Biology Research in Space’, held at the University of Freiburg, Germany. This workshop – jointly organised by the French and German space agencies, CNES and DLR – was embedded as satellite symposium into the Plant Biology Congress 2012, held by FESPB and EPSO, the two leading European organisations involved in plant research. Using this setup, it was also hoped that scientists from the so-called nonspace community would be attracted to the specific topic of plant biology in space. This idea proved very successful: more than 600 participants attended – for instance – the plenary lecture from Stan Roux on ‘New insights in plant biology gained from space research’

“…(2) Significant redistribution (sedimentation) of amyloplasts occurs in statocytes under gravistimulation in comparison with the displacement of other cell organelles. (3) Roots, shoots, pulvini, and gynophores are less able to react to gravity when there is no starch in the amyloplasts, starchless Arabidopsis thaliana (e.g., pgm1), tobacco, or rice (Oryza sativa, agpl1) mutants are weakly gravitropic Fitzelle and Kiss 2001;Fujihira et al 2000;Kiss and Sack 1990;Kordyum 2014;Kuznetsov and Hasenstein 1996;Moctezuma and Feldman 1999;Okamura et al 2015;Rioux et al 2015;Vitha et al 2007;Weise and Kiss 1999). Normal moss protonemata gravitropism in surrounding media with high-density also suggests the role of sedimenting amyloplasts as statoliths in gravitropism (Schwuchow et al 2002).…”

Molecular mechanisms of gravity perception and signal transduction in plants

Gravity is one of the environmental cues that direct plant growth and development. Recent investigations of different gravity signalling pathways have added complexity to how we think gravity is perceived. Particular cells within specific organs or tissues perceive gravity stimulus. Many downstream signalling events transmit the perceived information into subcellular, biochemical, and genomic responses. They are rapid, non-genomic, regulatory, and cell-specific. The chain of events may pass by signalling lipids, the cytoskeleton, intracellular calcium levels, protein phosphorylation-dependent pathways, proteome changes, membrane transport, vacuolar biogenesis mechanisms, or nuclear events. These events culminate in changes in gene expression and auxin lateral redistribution in gravity response sites. The possible integration of these signalling events with amyloplast movements or with other perception mechanisms is discussed. Further investigation is needed to understand how plants coordinate mechanisms and signals to sense this important physical factor.
