Abstract
Long-term manned space-exploration missions and the permanence of human colonies on orbital stations or planetary habitats will require the regeneration of resources onboard or in-situ. Bioregenerative Life Support Systems (BLSSs) are artificial environments where different compartments, involving both living organisms and physical-chemical processes, are integrated to achieve a safe, self-regulating, and chemically balanced Earth-like environment to support human life. Higher plants are key elements of such systems and Space greenhouses represent the producers' compartment. Growing plants in Space requires the knowledge of their growth responses not only to all environmental factors acting on Earth, but also to specific Space constraints such as altered gravity, ionizing radiations and confined volume. Moreover, cultivation techniques need to be adjusted considering such limitations. The type and intensity of environmental factors to be taken into account depend on the mission scenarios. Here, we summarize constraints and opportunities of cultivating higher plants in Space to regenerate resources and produce fresh food onboard. Both biological and agro-technological issues are considered briefly going through experiments both ground-based on Earth and in Space.

Abstract
Cellulosic secondary walls evolved convergently in coralline red macroalgae, reinforcing tissues against wave-induced breakage, despite differences in cellulose abundance, microfibril orientation, and wall structure. Cellulose-enriched secondary cell walls are the hallmark of woody vascular plants, which develop thickened walls to support upright growth and resist toppling in terrestrial environments. Here we investigate the striking presence and convergent evolution of cellulosic secondary walls in coralline red algae, which reinforce thalli against forces applied by crashing waves. Despite ostensible similarities to secondary wall synthesis in land plants, we note several structural and mechanical differences. In coralline red algae, secondary walls contain three-times more cellulose (~ 22% w/w) than primary walls (~ 8% w/w), and their presence nearly doubles the total thickness of cell walls (~ 1.2 µm thick). Field emission scanning electron microscopy revealed that cellulose bundles are cylindrical and lack any predominant orientation in both primary and secondary walls. His-tagged recombinant carbohydrate-binding module differentiated crystalline and amorphous cellulose in planta, noting elevated levels of crystalline cellulose in secondary walls. With the addition of secondary cell walls, Calliarthron genicular tissues become significantly stronger and tougher, yet remain remarkably extensible, more than doubling in length before breaking under tension. Thus, the development of secondary walls contributes to the strong-yet-flexible genicular tissues that enable coralline red algae to survive along wave-battered coastlines throughout the NE Pacific. This study provides an important evolutionary perspective on the development and biomechanical significance of secondary cell walls in a non-model, non-vascular plant.

PLANT BIOLOGY (STUTTGART, GERMANY) 2014; 16 Suppl 1:31-8.

Abstract
Human inhabitation of Space requires the efficient realisation of crop cultivation in bioregenerative life-support systems (BLSS). It is well known that plants can grow under Space conditions; however, perturbations of many biological phenomena have been highlighted due to the effect of altered gravity and its possible interactions with other factors. The mechanisms priming plant responses to Space factors, as well as the consequences of such alterations on crop productivity, have not been completely elucidated. These perturbations can occur at different stages of plant life and are potentially responsible for failure of the completion of the seed-to-seed cycle. After brief consideration of the main constraints found in the most recent experiments aiming to produce seeds in Space, we focus on two developmental phases in which the plant life cycle can be interrupted more easily than in others also on Earth. The first regards seedling development and establishment; we discuss reasons for slow development at the seedling stage that often occurs under microgravity conditions and can reduce successful establishment. The second stage comprises gametogenesis and pollination; we focus on male gamete formation, also identifying potential constraints to subsequent fertilisation. We finally highlight how similar alterations at cytological level can not only be common to different processes occurring at different life stages, but can be primed by different stress factors; such alterations can be interpreted within the model of 'stress-induced morphogenic response' (SIMR). We conclude by suggesting that a systematic analysis of all growth and reproductive phases during the plant life cycle is needed to optimise resource use in plant-based BLSS.

Abstract
In the cell walls of higher plants, cellulose chains are present in crystalline microfibril, with an amorphous part at the surface, or present as amorphous material. To assess the distribution and relative occurrence of the two forms of cellulose in the inflorescence stem of Arabidopsis, we used two carbohydrate-binding modules, CBM3a and CBM28, specific for crystalline and amorphous cellulose, respectively, with immunogold detection in TEM. The binding of the two CBMs displayed specific patterns suggesting that the synthesis of cellulose leads to variable nanodomains of cellulose structures according to cell type. In developing cell walls, only CBM3a bound significantly to the incipient primary walls, indicating that at the onset of its deposition cellulose is in a crystalline structure. As the secondary wall develops, the labeling with both CBMs becomes more intense. The variation of the labeling pattern by CBM3a between transverse and longitudinal sections appeared related to microfibril orientation and differed between fibers and vessels. Although the two CBMs do not allow the description of the complete status of cellulose microstructures, they revealed the dynamics of the deposition of crystalline and amorphous forms of cellulose during wall formation and between cell types adapting cellulose microstructures to the cell function.
