Fresh produce is an essential part of long-term, interspatial nutrition. However, resource constraints including launch mass, system power, and spacecraft cabin volume limit the amount of produce available for crew. Increasing the available oxygen to a plant’s root system stimulates overall growth but typical terrestrial approaches (i.e. sparging) are inappropriate for gas–liquid contacting in a microgravity environment. Terrestrial studies show the use of neutrally buoyant oxygen nanobubbles increases the plant nutritional and edible mass density for a given footprint. Thereby, addressing nutritional gaps in the current food system. This paper briefly evaluates the nutritional requirements for exploration astronauts and assesses the current approach for spaceflight produce provision. Then, presents the perspective opportunity to increase harvest index by implementing nanobubble technologies. Finally, a high-level review of nanobubble integration to enhance spaceflight food production systems and testing necessary to use nanobubbles in spaceflight systems is outlined.

Non-invasive Micro-test Technology (NMT) measures the ions/molecules in and out of the samples in a real-time, three-dimensional and dynamic manner without damaging the biological samples to obtain ions/molecules concentration, flow rate and movement direction, providing evidence for the study of the transport mechanism of biological and external environmental substances. This paper introduces the structure, operation system and technical advantages of NMT, and compares it with other ion testing technologies. Additionally, we conclude that it possesses the following attributes: no damage to biological activity, large range of measurable samples and targets, high sensitivity, and rich data content. Furthermore, its application progress in recent years has been reviewed and prospected from the perspectives of environmental bioremediation and stress physiology, which provides a reference for sustainable biological and environmental research.

In recent years, anthropogenic activities and climate change have significantly increased exposure of plants to environmental stresses (single or multiple) and pollutants, which negatively affect plant growth, survival, and productivity. Plants may activate an armament of defenses against such environmental stresses. Isoprene, the most abundant biogenic volatile organic compound emitted by plants, is supposed to induce stress tolerance directly, by quenching reactive oxygen species, or indirectly by strengthening photosynthetic membranes and reprogramming expression of genes that are involved in antioxidant defense mechanisms. On the other hand, isoprene is also involved in tropospheric chemistry that contributes to the production of air pollutants when mixing with anthropogenic gases. In this review, we summarized current knowledge about the impact of air and soil pollutants on isoprene emission from plants, focusing on possible feedback and feedforward mechanisms that may affect whole ecosystem functioning and evolution of plant species. Despite limited available information, especially about long-term effects of soil pollutants, it may be speculated that isoprene generally improves fitness of plants challenged by air and soil pollutants, and their interaction with other organisms.

Viscum combreticola Engl., an evergreen semi-parasitic mistletoe plant, is utilized in herbal medicines. Herein, a UHPLC-q-TOF-MS profiling and molecular networking approach were used to investigate the chemical interactions between V. combreticola and two of its host plants, Combretum erythrophyllum and Pseudolachnostylis maprouneifolia Pax. Moreover, in vitro grown V. combreticola seedlings were used to explore the host independence of the phytochemistry of these plants. The phytochemistry of V. combreticola was found to be independent and distinct from that of the host plants. Moreover, both mature V. combreticola and in vitro seedlings displayed diverse polyphenolic compounds but exhibited distinct metabolic profiles. Notably, the esterification of phenolic acids (hydroxycinnamic and benzoic acids) to quinic acid was a unique chemistry that was observed in both mature and in vitro grown V. combreticola. Beyond providing metabolic fingerprints of the studied samples, the UHPLC-q-TOF-MS and molecular networking effectively visualized plant-plant chemical relationships at a metabolite level.

This study explores the potential feasibility of cultivating two determinate-type bell peppers, i.e. Hungarian Enigma Hot (HEH) and Hungarian Enigma Sweet (HES), in a ground bioregenerative life-support device. Fruits of the Hugarian Engima Sweet (HES) variety is advantageous for digestion due to it has thin cuticle and collenchyma at the same time the parenchyma of mesocarp of it is thin. β-carotene and caspanthin were the dominant carotenoids in both fruit varieties. Up to 55 tentative phytochemicals were not only in fruits but also in green juice processed from green leafy shoots. The green juice was also a rich source of protein (24–27% w/w) and a source of macro- and microelements. The findings of this study could hold valuable insights for the advancement of sustainable food production and resource utilization in space environments, with potential applications for long-duration space missions and beyond.

Asparagus (Asparagus officinalis) is a crop with medicinal, horticultural, and nutritional uses. The basic leucine zipper (bZIP) family is a transcription factor family distributed throughout eukaryotes, including plants, and whose members participate in various biological processes, including plant growth, development, flowering, and stress responses. However, a few genome-wide studies of the bZIP family members have been reported. Here, 46 Asparagus bZIP members, named AobZIP01–AobZIP46, were identified from the reference genome via PFAM search and could be divided into 14 subgroups which were shown to be similar via motif and gene structure analysis. The molecular evolution, motif, and gene structure comparative analysis between A. officinalis and Arabidopsis indicated the accuracy of AobZIP member identification. Additionally, the cis-acting elements of the AobZIP members revealed that they might be associated with plant hormones and responses to abiotic stress. The collinear analysis predicted that the function of AobZIP members might be comparable to that of other species. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that AobZIP genes were enriched in the abscisic acid (ABA) pathway. Furthermore, the tissue-specific expression at the seedling stage revealed that root tissue could be used as a target tissue because of its high expression level. The expression of AobZIP genes determined by quantitative real-time PCR under abiotic stress at the seeding stage revealed that some AobZIP members could be candidate genes for plant breeding. This study offers insights for future research in improving the abiotic stress resistance of asparagus utilizing the AobZIP genes.

This study explores the role of a biostimulant derived from the seaweed Ascophyllum nodosum (AN) in mitigating salt stress in rice plants. The weekly (S+W) and biweekly (S+B) biostimulant treatments exhibited enhanced shoot and root biomass, maintained ionic balance, and increased pigment content (total chlorophyll increased by 26.35% and 31%, carotenoids by 11.90% and 16.67% in S+W and S+B treatments, respectively) compared to untreated salt-stressed plants (CS). Improved gas exchange parameters and PSII efficiency were observed in S+W and S+B treatments. AN-biostimulant treatments mitigated salt-induced oxidative stress by positively regulating the antioxidant defense system. Notably, a strong negative correlation was observed between antioxidants and oxidative markers. Furthermore, AN-biostimulant treatments induced key metabolites (organic acids, sugars, amino acids, flavonoids), emphasizing the integrated role of multiple pathways in enhancing salt tolerance in rice. These findings highlight the potential of AN biostimulants as eco-friendly tools for crop enhancement in challenging environments.
