Summary: In the future, space telescopes will investigate the Galaxy to search for evidence of life, with a focus on rocky planets and M dwarf-hosted super-Earths. Recent studies have found cyanobacteria capable of utilizing far-red light for photosynthesis, indicating the potential for exotic photosynthesis on planets around M dwarfs. Evaluating the photosynthetic performances of oxygenic organisms under such conditions highlights the importance of simulating both visible and far-red light components of an M dwarf spectrum.

Summary: Eukaryotic algae, including red algae, have the ability to use sunlight to fix carbon dioxide into biomass. Despite the diversity of algae metabolism, information on red algae is relatively scarce. This study focuses on the photosynthetic properties of a recently isolated mesophilic red algae and found that these cells are capable of acclimating, regulating chlorophyll content, and reorganizing thylakoid membranes under different light conditions.

Summary: The therapeutic thermal mud from the Euganean Thermal District in Italy is used for treating arthro-rheumatic diseases. The mud contains microbial polysaccharides (M-PS) that have anti-inflammatory and antioxidant activities, aiding in recovery from inflammation and regulating gene expression.

Summary: The study suggests that stem photosynthesis plays an adaptive role in woody plants that thrive in hot and dry ecosystems, aiding in their resistance to water shortage. The efficiency of stem photosynthesis was found to be higher in drought-tolerant species compared to drought-sensitive species, potentially leading to prolonged stomatal closure and cessation of carbon gain at the leaf level.

Summary: This study simulated photosynthesis under M-dwarf star light conditions using cyanobacteria and found that the biological oxygen production is similar to that under solar light. This suggests the possibility of detecting atmospheric biosignatures on exoplanets with M-dwarf stars if other conditions are met.

Summary: This study aimed to evaluate the palatability of gradually increasing amounts of Spirulina tablets in client-owned dogs and cats for a 6-week trial, as well as the owners' perception of the supplementation. The animals showed a high acceptance of Spirulina supplementation with no significant side effects. Owners, especially those of senior dogs, expressed willingness to continue using dietary Spirulina supplementation for their pets.

Summary: Oxygenic photosynthetic organisms (OPOs) are important targets in the search for life on exoplanets. After testing both cyanobacteria and microalgae under a simulated M-dwarf star spectrum, it was found that the growth of these organisms was not significantly affected. However, the growth of the moss Physcomitrium patens and the plant Arabidopsis thaliana showed some variation under different light conditions.

Summary: Leaves are the primary photosynthetic organs for most woody plants, but chloroplasts are also present in organs optimized for other functions. The efficiency of these chloroplasts is still unclear. In this study, we analyzed the chloroplasts in bark and wood of Fraxinus ornus saplings and found that despite receiving less light, wood chloroplasts were still capable of photosynthesis. The stem photosynthetic apparatus showed adaptations to low-light environments.

Summary: A new coil-shaped filamentous cyanobacterium, Thermospirulina andreolii, was isolated and characterized, belonging to the new genus Thermospirulina. This cyanobacterium has the potential to have antioxidant and anti-inflammatory activities, suggesting its potential contribution to the healing properties of the Euganean muds.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: This study cloned the full-length cDNA sequence of TaSPX3 gene in wheat and found that TaSPX3 responds to low phosphorus stress in multiple wheat genotypes. Overexpressing TaSPX3 can alleviate phosphorus deficiency symptoms and promote plant growth in Arabidopsis. The study also revealed the interaction of TaSPX3 with other genes related to the phosphorus starvation signaling pathway.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.

Summary: This study identified a cell number regulator gene called SlCNR8 in willow, which enhances resistance to trace metals in transgenic poplar seedlings. SlCNR8 reduces Cd uptake and accumulation, and can be used as a candidate gene for genetic improvement of phytostabilisation of trace metals.
